00:08
Hi everyone.
00:09
My name is Raja Prasath and I'm a designated support specialist
00:12
at Autodesk.
00:14
And I have 10 plus years of experience
00:16
in the design and execution of AEC projects,
00:19
and my areas of expertise include virtual design
00:22
and construction, building information modeling
00:24
and project management.
00:26
And I'm based in Bangalore, India.
00:28
And in today's session, I'll be teaching
00:31
about how you can review models and identify coordination
00:35
issues with Navisworks.
00:37
So before getting into the presentation,
00:39
the slide talks about the safe harbor statement.
00:42
And during the course of this presentation,
00:45
we may make statements regarding future events,
00:47
or statements regarding planned or future development
00:50
efforts for our existing or new products and services.
00:54
Hence the purchasing decision should not
00:56
be made based upon reliance on the statements.
00:59
The statements made in these presentations
01:01
are being made as of time and date of its presentation.
01:06
So today's learning objective is understanding
01:08
of how to utilize Navisworks for the design review
01:12
and coordination.
01:13
And the topics that we will be covering in today's session
01:17
are creating a federated model, navigating a model,
01:21
controlling the visibility, creating viewpoints
01:25
and markups, and running the clash
01:27
detective between the trades.
01:29
So overview of Navisworks, so what can Navisworks do?
01:35
So Navisworks helps you reduce potential clashes
01:38
and interference problems before the actual construction,
01:41
so that you can identify the clashes upfront virtually.
01:46
So that you can minimize the expensive delays due to error
01:50
and rework that may happen in the site later on,
01:54
so you can avoid all of that.
01:55
And also helps you aggregate the design and other team models
01:60
with different file formats.
02:01
You can aggregate them into one model
02:04
to effectively coordinate between different rates.
02:07
And Navisworks support a variety of file formats,
02:10
whether it is IFC or DWG, so all of these file
02:13
formats you'll be able to bring inside the Navisworks
02:16
and do the clash coordination.
02:19
And also you'll be able to visually interrogate
02:21
the model with advanced navigation tool sets, which
02:24
are available to you in Navisworks
02:26
and you can save viewpoints to share with the other team
02:29
members.
02:31
OK, so creating a federated model.
02:34
So a federated model is a combined building information
02:37
model, that is compiled from several BIM models
02:40
from different disciplines into one.
02:43
So why use Navisworks for a federated model?
02:47
So the first item is you can merge
02:49
models created from different design tools and disciplines.
02:53
Autodesk Navisworks is compatible with more than 80
02:56
file formats.
02:57
So you will be able to merge
03:01
is being supported by Navisworks,
03:03
and you'll be able to merge them into a single model
03:06
in Navisworks for clash coordination.
03:09
And it includes the 2D and 3D geometry as well as
03:13
the metadata.
03:14
The federated model can be used for coordination,
03:17
bidding or reviewing workflows.
03:19
And it contains all the tools and the 3D information,
03:23
so whatever is there in the authoring tool
03:25
you will be able to get it in the Navisworks as well.
03:29
And the federated model can be shared as read-only,
03:33
so that you have a control--
03:35
so that the model is not being changed and different
03:37
stakeholders can review and coordinate without making
03:41
any changes to the model.
03:43
And also Navisworks allows us to set up password and expiry
03:47
date, so which is an extra security for your models
03:50
and expiration date in case it's not the final model.
03:55
And the last one is file compaction.
03:58
So Navisworks models are lighter compared
03:60
to that of viewing in the authoring tools
04:02
so, you'll be able to navigate the model faster,
04:06
and you'll be able to bring in a large file sizes
04:10
inside Navisworks.
04:12
So the next item before we get into the depth
04:15
of the Navisworks, the preliminary items
04:17
that you will need to be familiar with
04:19
is the different types of Navisworks files.
04:23
So basically, there are three different Navisworks files.
04:27
The first one is an NWC file, the second one is an NWF,
04:32
and the third one is an NWD file.
04:35
So NWC stands for Navisworks Cache File,
04:38
and NWF stands for Navisworks File,
04:41
and NWD stands for Navisworks Document.
04:44
By default, when you open or append any native CAD or laser
04:49
scaned files in Autodesk Navisworks,
04:51
a cache file is created in the same directory and with
04:54
the same name as the original file,
04:56
but within an .nwc file extension.
04:59
So when you bring native file or a CAD file
05:03
automatically an NWC file is created,
05:06
so that's a cache file which the Navisworks use
05:09
to load it inside the software.
05:11
And the next one is NWF.
05:13
And NWF file contains links to the original native files
05:18
together with the Autodesk Navisworks-specific
05:20
data, such as review markups.
05:23
And no model geometry is saved with this file format,
05:26
this makes an NWF considerably smaller in size than an NWD.
05:31
So a Navisworks file is a working document,
05:34
and you can link all the NWC's.
05:36
So when you bring in an NWC into a Navisworks file
05:40
and then you save it for the first time,
05:42
it can be saved as an NWF or NWD.
05:46
So when you bring in a few NWC's, the option
05:49
that you can save is NWF or NWD.
05:51
The difference between them is that with, NWF it's
05:54
a work in progress file, and you can continue to work on it.
05:59
Whereas when you save it as an NWD,
06:01
it becomes a detached document, and this
06:04
can be used for sharing the document at a particular point
06:09
of time with different stakeholders with all
06:11
the viewpoints on the clashes.
06:14
So Navisworks document contains all the model geometry
06:17
together with the Navisworks-specific data
06:20
such as review markups.
06:22
And you can think of an NWD file as a snapshot
06:26
of the current state of the model.
06:28
NWD files are comparatively smaller
06:30
as they compress the CAD data up to 80% of the original size,
06:35
and these are detached models.
06:37
And NWD files can be shared with different stakeholders for them
06:42
to review the clashes.
06:45
Appending models in Navisworks works.
06:48
So once you open Navisworks, you will
06:51
be able to append models inside the Navisworks.
06:54
So you need to go to the Home tab
06:56
and click on append, when you click
06:58
on append you will get the screen and in the files of type
07:03
you will be able to select multiple file types as you can
07:06
see in the picture B over here.
07:08
It supports a variety of file formats,
07:11
so you'll be able to select that and append that
07:14
into your model.
07:16
So when you append a file into the model,
07:19
the selection tree allows you to select any part
07:22
of the appended models.
07:24
So in the Home tab, you will see selection tree
07:27
you will need to click on that and you
07:29
will get the panel, which is shown
07:30
on the left side of the screen.
07:32
And you will be able to see the model tree, which you have
07:37
brought inside the Navisworks.
07:39
And you will be able to drill down and select
07:42
the specific components within the file.
07:44
So you can drill down as much as it is available as
07:47
per the authoring tool.
07:49
So you will be able to click that
07:50
and you'll be able to drill inside the model.
07:53
And in this snapshot, we have selected the generic 12 inch
07:57
roof from the Architecture.nwc file.
08:01
And once you have selected that on the viewer
08:03
you will see that it has been highlighted with blue.
08:07
So selection tree helps you to drill down inside the model
08:10
and click on really the specific items of that particular file.
08:16
The next one is assigning colors to objects,
08:19
and you will be able to assign colors to objects
08:22
using the appearance profiler.
08:24
So in the Home tab that you have the appearance profiler,
08:27
you will need to click on that and you can select objects
08:31
by property or set.
08:33
So once you have selected that, you
08:35
will be able to choose specific colors
08:38
and you will be able to assign colors
08:39
to those specific models.
08:42
And once you have assigned colors to specific models
08:45
in a certain way, you will be able to save that as a .dat
08:49
file.
08:50
And you'll be able to take it across multiple projects,
08:53
so that you don't have to repeat it across multiple projects.
08:56
And you have to set it up one time
08:58
and then you can take it across multiple projects.
09:01
So in this slide, you'll be looking
09:03
at how to create a federated model, it's a demo video.
09:09
So you click on the structure, NWC you click on append
09:13
and then you append the structure file.
09:17
And then, you click on the append again
09:21
and then you append the MEP file as well.
09:24
And once you have appended that, you
09:28
will be able to click on that specific file
09:31
and then the file gets highlighted in the Navisworks.
09:35
And you will be able to drill down the model
09:40
and then select the different floors that are available.
09:48
So selection tree is very helpful in this way
09:50
that you are able to select individual elements
09:54
from the model that is coming in.
09:60
When you select a particular element on the right side
10:03
you can see that it is getting highlighted.
10:06
And if it is by shared coordinates, all of the models
10:08
or by internal origin all of the models
10:11
get aligned at the right position.
10:14
However, if you need to do some units and transform
10:17
you will still be able to do that
10:19
and you'll be able to rotate the model as well.
10:22
Now, let's say you want to move the model by Z axis,
10:25
you provide the certain--
10:27
by how much you want to move the model, you provide the units
10:31
and then you can see the model is
10:35
moved by 40 feet in the Z axis.
10:39
However, you need to use this with caution
10:41
and shared coordinates are recommended
10:45
as the models are aligned as soon as you append it.
10:48
And not you're not doing the transformation
10:51
in the Navisworks unless, it is needed.
10:56
The next one will be looking at is navigating a model.
11:00
So there is a variety of navigation tool sets
11:03
that are available in Navisworks for you to review the model.
11:08
So you have the navigation tool set and mouse wheel control,
11:12
gizmos are available and also global control interface
11:16
options are also available, where
11:18
you can change the options on the settings on how you want
11:22
to navigate inside the model.
11:25
So the navigation bar is very helpful in terms
11:28
of how you are reviewing the model
11:31
and it has a full navigation wheel, a pan, a zoom window,
11:35
orbit you can look around inside the model,
11:38
you can walk inside the model and you
11:40
can select any specific element of the model
11:43
once you are navigating inside.
11:46
So let's look at the demo of how you can do this one
11:49
and this in Navisworks.
11:52
So I am inside the model, so I'm in Navisworks 2020
11:58
and I have my files over here.
12:01
So on the right side, you will see these navigation toolbars
12:05
over here.
12:06
You can do a shortcut of shift and W
12:10
and you will get the navigation wheel.
12:14
So with this navigation wheel you
12:17
will be able to perform a variety of operations.
12:21
So as you can see over here, there
12:23
are quite a few options that are provided to you.
12:26
So the first one, let's look at the orbit.
12:28
So when you click on orbit, you just
12:30
need to hold the left mouse button
12:32
and then you will be able to orbit the model.
12:38
So that is used for orbit, and you
12:43
will be able to use pan to go up and down the model.
12:47
And you can use walk to walk inside the model.
12:53
So you can just go inside here, let's say,
12:56
if you want to go inside a specific floor.
13:02
I can just click here and then click on walk again.
13:07
So, I'm walking inside the model.
13:10
You can reduce the speed by slowing the mouse
13:15
and then you can see an arrow, which shows how
13:18
you can walk inside the model.
13:20
And you can use the pan even over here,
13:23
you can just go between different floors
13:25
to check the different items you can go up and down.
13:29
And you can as well click on look
13:31
to just stay in the same position
13:34
and then look around that particular location
13:36
to see how the connections are being made.
13:43
And you can zoom and rewind as well.
13:47
These are some of the other features that are available.
13:50
So you can use these features to review the models.
13:59
And once you have done when you want to come back always you
14:03
can come and click on the Home button over here,
14:06
it will take you to the overall home view.
14:09
This is your home view and you can close this one,
14:13
once it is done.
14:15
In the navigation tool sets, that's
14:17
another important feature, are the gizmos.
14:20
So you do get move gizmos, rotate and the scale gizmos.
14:24
This is very helpful for creating sections and also
14:28
creating any school boxes for you to view the model.
14:32
Let's go back to the software again,
14:36
for understanding the gizmos and how you can
14:38
work with it in the software.
14:41
So in the Home tab, you have the model and in the view
14:46
point just click on the viewpoint,
14:48
and you will see something called as enable sectioning.
14:50
So you click on enabled sectioning
14:52
and you will get the options over here,
14:55
you will be taken to the sectioning tools in which you
14:59
can click on the move.
15:01
So I'm going to use the orbit again to orbit the model.
15:05
So when I click on the move I have got a plane over here
15:09
and then I have got three handles over here,
15:12
so green, blue and red.
15:14
So I can use the blue arrow to actually slice the model,
15:19
so I can slice a model at a specific location
15:22
and then I can use this wheel over here
15:24
to actually see that in the front view
15:29
and again, I can orbit it as well.
15:34
You can use this for sectioning.
15:39
And let's say, you want to use the plane
15:44
for viewing in a plan view.
15:47
So what you can do is you can click on rotate,
15:49
and when you click on rotate, you
15:51
will be able to rotate that plane
15:54
and then you'll be able to see the model from the top view.
15:57
So if you want to give the exact 90 degrees,
15:60
so you can come here and then say, how much of rotation
16:03
you want to provide.
16:05
So I'm going to make this 90 exactly and then
16:08
make the other axis zero.
16:10
So in this case now what happens is again, I go to the move
16:13
and then I'm going to pull from the bottom up
16:16
and as I'm pulling it, you will be able to view that
16:23
from the top view.
16:25
So this is very helpful for you to look at the plan
16:29
overall and then check the plan and if there
16:32
is anything that needs to be changed
16:35
or any markups that needs to be done.
16:37
So you can just keep looking at--
16:41
you can stop at a certain location.
16:44
And if you want to look at the different MEP items,
16:49
that are running in the model, so you
16:52
will be able to view them using this tool.
16:57
And once you are done, you can remove anable sectioning,
17:01
so when you click on remove anable sectioning,
17:05
It will take you back to the original model and then
17:08
when you click on enabled sectioning
17:10
and then it brings you back along with the section.
17:14
And you do have an option to switch
17:16
between the planes and the box.
17:18
So instead of a plane if you would
17:20
like to see a particular item, you can create box as well.
17:25
And box has an option of scaling,
17:28
so you can click on scale as well,
17:31
and then you can just make it smaller at a particular level
17:38
or detail.
17:43
So you can use the box let's say,
17:45
for example you want to view a particular level
17:49
both from the top and the bottom,
17:52
so you will be able to use this scale option to do that.
17:58
Let me go back to the plains and then I'm
18:00
going to remove the enabled sectioning.
18:03
So this is what I wanted to show you in the gizmos option, where
18:08
you can use the sectioning tools and leverage these features
18:11
that are available for you to effectively view
18:14
the model from the plan view or from the section
18:18
by slicing and dicing.
18:20
The next topic that we will be discussing
18:22
is controlling the visibility.
18:24
There are a couple of features and tools
18:26
that are available in Navisworks for you to hide selected
18:30
objects, and it is very helpful when
18:32
you want to view certain elements that are being hidden
18:36
by the architectural and you want
18:38
to see the skeleton of the model,
18:40
you will be able to do that.
18:42
So you can hide the objects in the current selection,
18:44
so that they are not drawn in the scene view this is useful
18:47
when you want to remove specific parts of the model.
18:51
And you can click on the Home tab and visibility panel
18:55
and hide or you can also use a command entry,
18:58
which is Control plus H which will
19:00
hide that particular object.
19:02
Let's say, for example, you select a particular object
19:05
and you press Control H and it will
19:07
be hidden so that you can see what is behind that.
19:11
So you will be able to do that using hide option,
19:15
and you can unhide the objects as well.
19:17
So let's say you have hidden it and then you want to unhide it,
19:20
you'll be able to do that.
19:22
You can hide all items except those currently selected,
19:26
so that they are not drawn in the scene view,
19:28
this is useful when you only want
19:29
to see specific parts of the model.
19:32
In the selection tree the items appear gray
19:34
when marked as hidden, so from the selection tree
19:37
you will be able to hide a few objects.
19:40
Let's say, for example, you want to hide the architecture
19:43
and structure and then you want to see just the MEP,
19:46
you will be able to do hide unselected option, which
19:50
is available in the Navisworks Home tab, Home tab, visibility
19:54
panel, hide unselected.
19:55
Whatever is not selected will be completely hidden in the view,
19:59
so you do have a good view of what are the elements that you
20:02
want to see.
20:04
Reveal selected objects, you can reveal a selection of objects
20:07
that are hidden, because you can select the objects
20:10
in the scene view you need to select them
20:12
in the selection tree.
20:13
Let's say, few of the objects that are hidden
20:15
and then you want to bring them back
20:17
you will be able to reveal those objects, which are selected
20:21
in the selection tree.
20:22
And then reveal all hidden objects,
20:24
so that is an option in Navisworks visibility
20:27
panel, which says unhide all.
20:30
When you unhide all and nothing is hidden everything
20:32
comes back to its previous view, so no objects will be hidden.
20:37
And sectioning plane and box, so click viewpoint tab,
20:43
sectioning panel and enable sectioning.
20:45
So we saw this in the demo as well,
20:47
that you can click on sectioning and then you
20:50
can click on the different gizmos that are available.
20:53
And Autodesk Navisworks opens the sectioning tools
20:56
tab on the ribbon and draws a section plane
20:58
through the model in the scene view.
21:00
And you will be able to leverage and view the section
21:05
and as mentioned, you will be able to choose
21:07
between plane and a box.
21:09
And so the box is now officially present on the screen in the B
21:14
image and with the move gizmo enabled by default.
21:18
So you can use both of these options.
21:22
So let's look at a demo video of controlling the visibility,
21:26
so you go to the selection tree you can just click it
21:29
and then you can say hide, which is available in the item tools,
21:32
so it's hidden then you can see the inside of the model.
21:39
And you can also say hide unselected,
21:40
since only that wall is selected when you did
21:43
hide unselected it unselected--
21:46
they just hidden whatever is unselected, right?
21:49
And then you click on unhide all and then
21:51
it brought back everything.
21:53
And then there is a couple of ways to do this one,
21:56
so we did that directly using the item tools
21:59
or in the selection tree you can just
22:00
click on it and right click and then say hide.
22:03
So there is quite a few ways you can hide and unhide
22:06
objects in Navisworks.
22:08
So as you've seen here, either you
22:10
want to do it in the selection tree it's possible,
22:12
or either you want to just right click that element
22:15
and say hide, even that is possible as well.
22:18
The next important feature that we will be talking about
22:21
is creating viewpoints and markups.
22:25
So in Navisworks you will be able to create viewpoints,
22:29
which enables you to add annotations to the viewpoints
22:34
and clash detection results.
22:36
So when you say viewpoints, you can
22:38
create folders as well as shown in the image B,
22:41
you can have like architectural structure and maybe folders.
22:44
And you can create these viewpoints
22:46
and place them under the folders.
22:48
The benefit of the viewpoints is that, let's say, you
22:51
have created a couple of viewpoints,
22:53
then it'll be easier for you to just directly go
22:55
to that particular viewpoint when
22:57
you want to share your findings with the other users,
22:60
instead of scrolling down to that particular point
23:02
every time.
23:03
So viewpoints helps in that way that you
23:06
have a snapshot of the different issues,
23:10
that you want to review with the team members
23:11
and you will be able to save those viewpoints in Navisworks.
23:16
So you click on viewpoint tab and then
23:18
you can save those viewpoints, and then
23:21
either directly over there or right-click
23:24
in the same viewpoints and then again you
23:26
can click on save your point.
23:27
So there are two ways that you will be able to do that.
23:30
As you can see over here, along the save viewpoint,
23:34
there are a few more options that are available in,
23:37
let's say, for example, if you want
23:38
to create a new folder within this one with a specific date
23:41
you will still be able to do that.
23:44
Let's look at the viewpoints demo in this video.
23:48
So let's say you can create--
23:50
so I have created a viewpoint over here,
23:52
which is let's say, door view one
23:55
and then you scroll the model and then
23:58
you create another viewpoint, let's say door view two.
24:03
So in this case, there are two viewpoints, right?
24:05
So it has created a snapshot and then
24:09
you can switch between these two views, view one and view two,
24:13
then you will be able to look at from that particular angle.
24:17
And again you can go inside and start
24:19
orbiting from that specific view,
24:22
but this snapshot itself doesn't change as soon as you
24:26
create that viewpoint.
24:27
It just stays at that particular location
24:30
looking at the certain way that you have decided when
24:33
you have created the viewpoint.
24:35
So with the viewpoints, you will be
24:37
able to use the review features that are
24:39
available in the Navisworks.
24:42
So when you go to review there are
24:43
a couple of options that is being provided to you.
24:46
So the first one is measurements,
24:48
you will be able to measure between the two
24:51
elements in Navisworks.
24:52
And you red line it and then highlight it.
24:57
And you can add tags over there, and also you
25:00
can add comments as well.
25:02
So if the viewpoint was not saved it,
25:05
a new viewpoint will be created.
25:08
So if there is no viewpoints that you have saved,
25:11
a new viewpoint will be created when
25:14
you do the reviews and markups, so they can stay on a viewpoint
25:19
only.
25:20
So when using the lock, select None
25:22
to reset the reference plane.
25:24
Over here in this picture, as you can see the red line
25:28
markings are done and the measurement is shown.
25:31
And then you can also do a couple of notes over here
25:35
let's say, for example, if you want to say I conveyed this
25:38
to the team members to add a column here,
25:39
and column missing that you'll be
25:41
able to do that using the reviews.
25:44
And you can tag and comments will
25:46
provide additional information to manage that review process.
25:49
So in that particular view, you'll be able to tag.
25:52
You can add the date, author, comment ID and status.
25:56
You will be able to do that and also
25:58
use the find comments window or to set up and run
26:00
a search for tags and comments based on the metadata.
26:05
So from the comments section find and you can run reports
26:10
on what are the items that are modified between a certain date
26:13
to a certain date, that you will be able to get
26:15
that list from there.
26:17
And use the controls on the Tags panel
26:20
to navigate through the tags, so you
26:23
can navigate through the tags using this tags
26:26
option over here.
26:27
So let's look at the markups demo, so I click on review
26:31
and then when you click on review,
26:32
you have a couple of options such as line or a revision
26:35
cloud, so you'll be able to do that.
26:38
You can start drawing directly in that particular view.
26:43
And then you can click on measure
26:45
and you can lock the access as well, so
26:47
that the access doesn't move.
26:49
So you can click on perpendicular
26:52
and then check, OK, what is the distance between those two
26:56
columns?
26:56
And it would be highlighted.
26:58
First it highlights unless you click it
27:00
on convert to red line, then it gets converted to the red line.
27:05
Again you can convert it to red line
27:06
and it shows the dimensions between that,
27:10
and then you can put a revision cloud
27:13
or add further comments to that particular view.
27:23
So you can add the text over there,
27:27
and then you can add an arrow pointing
27:29
to that particular location.
27:34
So once you have done you can rename that as per you
27:40
want to rename it and even you can move it
27:42
inside the different folders, depending
27:44
on who needs to take action based on the comments that
27:48
is provided.
27:49
You click on that, you can further
27:51
add more description rather than just adding all the description
27:56
directly in the view, you'll be able to further add
27:59
more description on when the stakeholders looking at it,
28:03
they will be able to look at this comment
28:05
and then make the changes accordingly.
28:07
So you can add those comments you click on view comments
28:09
and you will be able to see those comments that
28:13
has been provided for that particular viewpoint.
28:17
And you will be able to search between the different dates
28:21
on the different review items that has been created,
28:29
and you'll be able to also click on tags to go over item
28:34
by item.
28:35
So this is very useful, when you want
28:37
to communicate more information to the different stakeholders
28:41
in your coordination meeting.
28:42
Other than just a viewpoint, you can further
28:44
add more of these reviews and convey those information
28:49
to them, so that you'll be able to come
28:51
to an effective resolution.
28:54
The last part that we'll be covering in this lecture
28:57
is running the clash detector between the trades, which
29:01
is one of the powerful feature of Navisworks.
29:05
So running the clash directive between trades and Navisworks
29:08
provides more options and control over your clash test
29:12
in comparison to Glue, and under the Home tab select clash
29:16
detective, so you can go in the Home tab
29:19
and you will see a particular button, which
29:22
is called the clash detector.
29:24
When you click on that, then you will get the items
29:28
B and C pop up in your screen.
29:30
So you will get the screen and if you
29:32
have dual monitors it is even better
29:35
you can take these clash detector screens
29:38
instead of overlaying to a different screen.
29:41
So once you have done that, you will need to add the tests,
29:45
so in item C it shows all the tests that are there,
29:48
when you see the B, right?
29:50
In image B there is something called as add test.
29:53
So you'll be able to keep adding tests over there.
29:56
So let's say you want to test or check between architecture
30:00
and structure, so you click on add test,
30:02
let's say you want to check between the structure
30:04
and the mechanical you click on add test.
30:06
So you keep adding these tests let's
30:09
say, for example as per your record
30:10
I recommend maybe you have 10 to 12 tests.
30:13
So you will see the entire list in the C image, which
30:17
is shown over there, so you clicked on a test
30:19
and you will see all of that.
30:20
And also you will see two columns
30:23
over there one is selection A and selection B,
30:26
and in selection A it shows all of the models and WC's that
30:31
are appended to the file and same it is shown
30:35
and the selection B as well.
30:38
Now, you'll be able to select, let's say architecture
30:41
in selection A and structure in selection B
30:44
and then you will be able to run a test between those.
30:47
Or you can select MEP in selection A and structure
30:51
in selection B and you will be able to run the test.
30:55
So whatever you are selecting, you
30:56
can give the specific name in the test.
30:60
Let's say if you want to clash between MEP
31:02
and structure for that particular test
31:05
you have the name as MEP versus structure or MEP
31:08
underscore structure, so that you are clear on what
31:11
is clashing between the two whenever you come back
31:14
to the work in progress model.
31:16
To choose the elements to test, so you
31:19
can choose between the different elements,
31:22
let's say, for example you want to clash
31:23
between the first floor architecture
31:26
versus the first floor structure,
31:27
so you will be able to select that.
31:29
And you can also provide a tolerance in the settings,
31:33
let's say you want Navisworks to ignore
31:37
the clash for that particular MM, you can mention that.
31:41
And once you have mentioned that,
31:42
Navisworks will ignore that based on the tolerance.
31:46
For example, if there is an insulation in the pipe and then
31:50
you want to ignore it, so you'll be
31:51
able to set those tolerance in this case.
31:53
And there are different clash types
31:55
that you will be able to select, hard, hard conservative,
31:59
clearance, and duplicates.
32:01
So you'll be able to choose between these different types.
32:05
Hard shows all the hard clashes, hard conservative
32:08
shows even a slightest touch of any triangulations
32:12
that happen in the software.
32:13
Even if elements are running parallel and even the slightest
32:16
touch will be highlighted in hard conservative,
32:20
and clearance for if you want to check any clearance.
32:23
And if you want to check for any duplicates in the model,
32:26
so you'll be able to choose their duplicates clash type.
32:29
And once you have selected that, then you
32:31
will be able to run the test.
32:33
So once you have run the test, so be there in the select tab.
32:38
So we were in the select Tab over here.
32:40
So when you click on Run test only after that the Results
32:45
tab get populated, and then when you click on the results tab
32:49
you will see this interface of all the clashes
32:51
that you can see.
32:52
So once that test has been run you
32:55
will find a significant number of clashes,
32:57
so this can now be grouped up and distributed via Glue
32:60
to allow other team members to view and rectify.
33:03
And if you're using BIM 360 Glue you
33:05
will be able to connect to BIM 360 Glue.
33:07
And Navisworks you will be able to group these clashes
33:11
and assign it to the right team members using viewpoints,
33:16
so that is possible as well.
33:17
So you can group clashes either by selecting
33:20
multiple related clashes or clicking on New group.
33:23
So either you can say click on New group
33:26
or multiple related clashes.
33:28
You can select those clashes and then click on create group.
33:31
So the reason we are grouping the clashes is because you
33:35
may have a lot of clashes, but then when you are looking
33:38
at the issues, so a couple of clashes
33:40
can be combined to a single issue.
33:42
This way you can make it like each group
33:45
is an issue that needs to be addressed,
33:47
rather than going into each clash
33:49
and assigning it to different users.
33:51
So it's always better if a group of these clashes
33:55
can be bundled up as a single issue.
33:57
You will need to do that in Navisworks,
33:60
so that they can be bundled and looked at as a single issue
34:03
to be actioned upon.
34:04
And the most common way of grouping clashes is by item.
34:07
The item windows at the bottom shows
34:09
what elements are clashing, select group
34:11
clashes involving item.
34:13
So in the item you will also see further details, as well
34:18
on what is clashing with what.
34:20
And similarly you will be able to see that in the view
34:23
as well, so you can go looking at the view
34:26
and then grouping the clashes as well.
34:28
So if you want to create views that
34:30
track the progress of coordination in an area,
34:32
set the highlighting to use status color each time
34:35
you run this report.
34:37
And repeat this step until you're done grouping clashes.
34:41
And also there are few options that are available where you
34:45
can dim other or hide other .
34:46
So let's say you have selected clash five,
34:49
when you click on Dim other, the other elements
34:52
will be in a ghosted mode.
34:53
However, when you click on hide other,
34:55
you will see only these two elements clash
34:58
of what is clashing with what.
35:00
So once you have grouped that, you
35:02
do have an option in the tab of the reports tab,
35:06
you will be able to create reports.
35:08
There are quite a few options that you can do,
35:11
whether it is group headers only or individual clashes
35:14
or everything.
35:15
And then as well can filter it based
35:17
on, whether you want to create the report just
35:20
for the new clashes, active clashes
35:22
or reviewed, approved or resolved,
35:24
you'll be able to further filter down
35:26
depending on how you want to get that report.
35:29
And then the report format, so you can either
35:33
have an HTML format or you can have it as a viewpoints.
35:37
So whatever clashes that you have identified
35:39
can be saved as a viewpoint in a report format,
35:43
so you click on write a report and they will
35:45
be saved as the viewpoints.
35:49
So let's look at the clash detection demo video.
35:52
So you click on the clash detective tab,
35:55
and then this particular tab opens up and you can pin it
35:60
and that's called test one.
36:03
So you can change it to the name of your choice, which
36:08
makes more sense for you to understand
36:11
what is clashing with what.
36:12
So we have selected MEP first-floor and the structure
36:15
first-floor.
36:17
So that the next is a hard clash, so run report then
36:21
it is going to show you like all of these clashes.
36:25
And since it is Dim other, it is actually
36:28
making the other elements transparent
36:29
and you can review all of these clashes over here.
36:36
And you can select a few clashes and then
36:42
you put them under the single group.
36:48
You can work on a resolution for that particular issue
36:53
and you can give a specific name to that.
37:00
And then you can choose the colors between that,
37:04
so when you select item colors it
37:07
will highlight between red and green.
37:10
So you will be aware of these two elements, what
37:13
is clashing with what.
37:14
And when you click on hide other,
37:15
the other elements would be hidden
37:17
and when you come out of the Dim other
37:19
you will see the entire model as well.
37:30
When you go to the Report tab, you
37:32
will be able to run the report and let's say, for example we
37:37
want to write a report in the HTML format,
37:40
so you can save the report in the HTML format.
37:44
And once that report is written you,
37:46
will get this report, which you will
37:48
be able to share with the different users.
37:52
It gives a snapshot of that clash, the name, distance,
37:56
description, flash point and date created.
37:59
And when you click on that image it gets bigger,
38:01
as well for you to review those flashes.
38:05
Thank you everyone.
38:06
We are we are at the end of the session
38:08
and for further learning, we have Customer Success
38:11
Hub, which is customersucess.autodesk.com,
38:13

00:08
Hi everyone.
00:09
My name is Raja Prasath and I'm a designated support specialist
00:12
at Autodesk.
00:14
And I have 10 plus years of experience
00:16
in the design and execution of AEC projects,
00:19
and my areas of expertise include virtual design
00:22
and construction, building information modeling
00:24
and project management.
00:26
And I'm based in Bangalore, India.
00:28
And in today's session, I'll be teaching
00:31
about how you can review models and identify coordination
00:35
issues with Navisworks.
00:37
So before getting into the presentation,
00:39
the slide talks about the safe harbor statement.
00:42
And during the course of this presentation,
00:45
we may make statements regarding future events,
00:47
or statements regarding planned or future development
00:50
efforts for our existing or new products and services.
00:54
Hence the purchasing decision should not
00:56
be made based upon reliance on the statements.
00:59
The statements made in these presentations
01:01
are being made as of time and date of its presentation.
01:06
So today's learning objective is understanding
01:08
of how to utilize Navisworks for the design review
01:12
and coordination.
01:13
And the topics that we will be covering in today's session
01:17
are creating a federated model, navigating a model,
01:21
controlling the visibility, creating viewpoints
01:25
and markups, and running the clash
01:27
detective between the trades.
01:29
So overview of Navisworks, so what can Navisworks do?
01:35
So Navisworks helps you reduce potential clashes
01:38
and interference problems before the actual construction,
01:41
so that you can identify the clashes upfront virtually.
01:46
So that you can minimize the expensive delays due to error
01:50
and rework that may happen in the site later on,
01:54
so you can avoid all of that.
01:55
And also helps you aggregate the design and other team models
01:60
with different file formats.
02:01
You can aggregate them into one model
02:04
to effectively coordinate between different rates.
02:07
And Navisworks support a variety of file formats,
02:10
whether it is IFC or DWG, so all of these file
02:13
formats you'll be able to bring inside the Navisworks
02:16
and do the clash coordination.
02:19
And also you'll be able to visually interrogate
02:21
the model with advanced navigation tool sets, which
02:24
are available to you in Navisworks
02:26
and you can save viewpoints to share with the other team
02:29
members.
02:31
OK, so creating a federated model.
02:34
So a federated model is a combined building information
02:37
model, that is compiled from several BIM models
02:40
from different disciplines into one.
02:43
So why use Navisworks for a federated model?
02:47
So the first item is you can merge
02:49
models created from different design tools and disciplines.
02:53
Autodesk Navisworks is compatible with more than 80
02:56
file formats.
02:57
So you will be able to merge
03:01
is being supported by Navisworks,
03:03
and you'll be able to merge them into a single model
03:06
in Navisworks for clash coordination.
03:09
And it includes the 2D and 3D geometry as well as
03:13
the metadata.
03:14
The federated model can be used for coordination,
03:17
bidding or reviewing workflows.
03:19
And it contains all the tools and the 3D information,
03:23
so whatever is there in the authoring tool
03:25
you will be able to get it in the Navisworks as well.
03:29
And the federated model can be shared as read-only,
03:33
so that you have a control--
03:35
so that the model is not being changed and different
03:37
stakeholders can review and coordinate without making
03:41
any changes to the model.
03:43
And also Navisworks allows us to set up password and expiry
03:47
date, so which is an extra security for your models
03:50
and expiration date in case it's not the final model.
03:55
And the last one is file compaction.
03:58
So Navisworks models are lighter compared
03:60
to that of viewing in the authoring tools
04:02
so, you'll be able to navigate the model faster,
04:06
and you'll be able to bring in a large file sizes
04:10
inside Navisworks.
04:12
So the next item before we get into the depth
04:15
of the Navisworks, the preliminary items
04:17
that you will need to be familiar with
04:19
is the different types of Navisworks files.
04:23
So basically, there are three different Navisworks files.
04:27
The first one is an NWC file, the second one is an NWF,
04:32
and the third one is an NWD file.
04:35
So NWC stands for Navisworks Cache File,
04:38
and NWF stands for Navisworks File,
04:41
and NWD stands for Navisworks Document.
04:44
By default, when you open or append any native CAD or laser
04:49
scaned files in Autodesk Navisworks,
04:51
a cache file is created in the same directory and with
04:54
the same name as the original file,
04:56
but within an .nwc file extension.
04:59
So when you bring native file or a CAD file
05:03
automatically an NWC file is created,
05:06
so that's a cache file which the Navisworks use
05:09
to load it inside the software.
05:11
And the next one is NWF.
05:13
And NWF file contains links to the original native files
05:18
together with the Autodesk Navisworks-specific
05:20
data, such as review markups.
05:23
And no model geometry is saved with this file format,
05:26
this makes an NWF considerably smaller in size than an NWD.
05:31
So a Navisworks file is a working document,
05:34
and you can link all the NWC's.
05:36
So when you bring in an NWC into a Navisworks file
05:40
and then you save it for the first time,
05:42
it can be saved as an NWF or NWD.
05:46
So when you bring in a few NWC's, the option
05:49
that you can save is NWF or NWD.
05:51
The difference between them is that with, NWF it's
05:54
a work in progress file, and you can continue to work on it.
05:59
Whereas when you save it as an NWD,
06:01
it becomes a detached document, and this
06:04
can be used for sharing the document at a particular point
06:09
of time with different stakeholders with all
06:11
the viewpoints on the clashes.
06:14
So Navisworks document contains all the model geometry
06:17
together with the Navisworks-specific data
06:20
such as review markups.
06:22
And you can think of an NWD file as a snapshot
06:26
of the current state of the model.
06:28
NWD files are comparatively smaller
06:30
as they compress the CAD data up to 80% of the original size,
06:35
and these are detached models.
06:37
And NWD files can be shared with different stakeholders for them
06:42
to review the clashes.
06:45
Appending models in Navisworks works.
06:48
So once you open Navisworks, you will
06:51
be able to append models inside the Navisworks.
06:54
So you need to go to the Home tab
06:56
and click on append, when you click
06:58
on append you will get the screen and in the files of type
07:03
you will be able to select multiple file types as you can
07:06
see in the picture B over here.
07:08
It supports a variety of file formats,
07:11
so you'll be able to select that and append that
07:14
into your model.
07:16
So when you append a file into the model,
07:19
the selection tree allows you to select any part
07:22
of the appended models.
07:24
So in the Home tab, you will see selection tree
07:27
you will need to click on that and you
07:29
will get the panel, which is shown
07:30
on the left side of the screen.
07:32
And you will be able to see the model tree, which you have
07:37
brought inside the Navisworks.
07:39
And you will be able to drill down and select
07:42
the specific components within the file.
07:44
So you can drill down as much as it is available as
07:47
per the authoring tool.
07:49
So you will be able to click that
07:50
and you'll be able to drill inside the model.
07:53
And in this snapshot, we have selected the generic 12 inch
07:57
roof from the Architecture.nwc file.
08:01
And once you have selected that on the viewer
08:03
you will see that it has been highlighted with blue.
08:07
So selection tree helps you to drill down inside the model
08:10
and click on really the specific items of that particular file.
08:16
The next one is assigning colors to objects,
08:19
and you will be able to assign colors to objects
08:22
using the appearance profiler.
08:24
So in the Home tab that you have the appearance profiler,
08:27
you will need to click on that and you can select objects
08:31
by property or set.
08:33
So once you have selected that, you
08:35
will be able to choose specific colors
08:38
and you will be able to assign colors
08:39
to those specific models.
08:42
And once you have assigned colors to specific models
08:45
in a certain way, you will be able to save that as a .dat
08:49
file.
08:50
And you'll be able to take it across multiple projects,
08:53
so that you don't have to repeat it across multiple projects.
08:56
And you have to set it up one time
08:58
and then you can take it across multiple projects.
09:01
So in this slide, you'll be looking
09:03
at how to create a federated model, it's a demo video.
09:09
So you click on the structure, NWC you click on append
09:13
and then you append the structure file.
09:17
And then, you click on the append again
09:21
and then you append the MEP file as well.
09:24
And once you have appended that, you
09:28
will be able to click on that specific file
09:31
and then the file gets highlighted in the Navisworks.
09:35
And you will be able to drill down the model
09:40
and then select the different floors that are available.
09:48
So selection tree is very helpful in this way
09:50
that you are able to select individual elements
09:54
from the model that is coming in.
09:60
When you select a particular element on the right side
10:03
you can see that it is getting highlighted.
10:06
And if it is by shared coordinates, all of the models
10:08
or by internal origin all of the models
10:11
get aligned at the right position.
10:14
However, if you need to do some units and transform
10:17
you will still be able to do that
10:19
and you'll be able to rotate the model as well.
10:22
Now, let's say you want to move the model by Z axis,
10:25
you provide the certain--
10:27
by how much you want to move the model, you provide the units
10:31
and then you can see the model is
10:35
moved by 40 feet in the Z axis.
10:39
However, you need to use this with caution
10:41
and shared coordinates are recommended
10:45
as the models are aligned as soon as you append it.
10:48
And not you're not doing the transformation
10:51
in the Navisworks unless, it is needed.
10:56
The next one will be looking at is navigating a model.
11:00
So there is a variety of navigation tool sets
11:03
that are available in Navisworks for you to review the model.
11:08
So you have the navigation tool set and mouse wheel control,
11:12
gizmos are available and also global control interface
11:16
options are also available, where
11:18
you can change the options on the settings on how you want
11:22
to navigate inside the model.
11:25
So the navigation bar is very helpful in terms
11:28
of how you are reviewing the model
11:31
and it has a full navigation wheel, a pan, a zoom window,
11:35
orbit you can look around inside the model,
11:38
you can walk inside the model and you
11:40
can select any specific element of the model
11:43
once you are navigating inside.
11:46
So let's look at the demo of how you can do this one
11:49
and this in Navisworks.
11:52
So I am inside the model, so I'm in Navisworks 2020
11:58
and I have my files over here.
12:01
So on the right side, you will see these navigation toolbars
12:05
over here.
12:06
You can do a shortcut of shift and W
12:10
and you will get the navigation wheel.
12:14
So with this navigation wheel you
12:17
will be able to perform a variety of operations.
12:21
So as you can see over here, there
12:23
are quite a few options that are provided to you.
12:26
So the first one, let's look at the orbit.
12:28
So when you click on orbit, you just
12:30
need to hold the left mouse button
12:32
and then you will be able to orbit the model.
12:38
So that is used for orbit, and you
12:43
will be able to use pan to go up and down the model.
12:47
And you can use walk to walk inside the model.
12:53
So you can just go inside here, let's say,
12:56
if you want to go inside a specific floor.
13:02
I can just click here and then click on walk again.
13:07
So, I'm walking inside the model.
13:10
You can reduce the speed by slowing the mouse
13:15
and then you can see an arrow, which shows how
13:18
you can walk inside the model.
13:20
And you can use the pan even over here,
13:23
you can just go between different floors
13:25
to check the different items you can go up and down.
13:29
And you can as well click on look
13:31
to just stay in the same position
13:34
and then look around that particular location
13:36
to see how the connections are being made.
13:43
And you can zoom and rewind as well.
13:47
These are some of the other features that are available.
13:50
So you can use these features to review the models.
13:59
And once you have done when you want to come back always you
14:03
can come and click on the Home button over here,
14:06
it will take you to the overall home view.
14:09
This is your home view and you can close this one,
14:13
once it is done.
14:15
In the navigation tool sets, that's
14:17
another important feature, are the gizmos.
14:20
So you do get move gizmos, rotate and the scale gizmos.
14:24
This is very helpful for creating sections and also
14:28
creating any school boxes for you to view the model.
14:32
Let's go back to the software again,
14:36
for understanding the gizmos and how you can
14:38
work with it in the software.
14:41
So in the Home tab, you have the model and in the view
14:46
point just click on the viewpoint,
14:48
and you will see something called as enable sectioning.
14:50
So you click on enabled sectioning
14:52
and you will get the options over here,
14:55
you will be taken to the sectioning tools in which you
14:59
can click on the move.
15:01
So I'm going to use the orbit again to orbit the model.
15:05
So when I click on the move I have got a plane over here
15:09
and then I have got three handles over here,
15:12
so green, blue and red.
15:14
So I can use the blue arrow to actually slice the model,
15:19
so I can slice a model at a specific location
15:22
and then I can use this wheel over here
15:24
to actually see that in the front view
15:29
and again, I can orbit it as well.
15:34
You can use this for sectioning.
15:39
And let's say, you want to use the plane
15:44
for viewing in a plan view.
15:47
So what you can do is you can click on rotate,
15:49
and when you click on rotate, you
15:51
will be able to rotate that plane
15:54
and then you'll be able to see the model from the top view.
15:57
So if you want to give the exact 90 degrees,
15:60
so you can come here and then say, how much of rotation
16:03
you want to provide.
16:05
So I'm going to make this 90 exactly and then
16:08
make the other axis zero.
16:10
So in this case now what happens is again, I go to the move
16:13
and then I'm going to pull from the bottom up
16:16
and as I'm pulling it, you will be able to view that
16:23
from the top view.
16:25
So this is very helpful for you to look at the plan
16:29
overall and then check the plan and if there
16:32
is anything that needs to be changed
16:35
or any markups that needs to be done.
16:37
So you can just keep looking at--
16:41
you can stop at a certain location.
16:44
And if you want to look at the different MEP items,
16:49
that are running in the model, so you
16:52
will be able to view them using this tool.
16:57
And once you are done, you can remove anable sectioning,
17:01
so when you click on remove anable sectioning,
17:05
It will take you back to the original model and then
17:08
when you click on enabled sectioning
17:10
and then it brings you back along with the section.
17:14
And you do have an option to switch
17:16
between the planes and the box.
17:18
So instead of a plane if you would
17:20
like to see a particular item, you can create box as well.
17:25
And box has an option of scaling,
17:28
so you can click on scale as well,
17:31
and then you can just make it smaller at a particular level
17:38
or detail.
17:43
So you can use the box let's say,
17:45
for example you want to view a particular level
17:49
both from the top and the bottom,
17:52
so you will be able to use this scale option to do that.
17:58
Let me go back to the plains and then I'm
18:00
going to remove the enabled sectioning.
18:03
So this is what I wanted to show you in the gizmos option, where
18:08
you can use the sectioning tools and leverage these features
18:11
that are available for you to effectively view
18:14
the model from the plan view or from the section
18:18
by slicing and dicing.
18:20
The next topic that we will be discussing
18:22
is controlling the visibility.
18:24
There are a couple of features and tools
18:26
that are available in Navisworks for you to hide selected
18:30
objects, and it is very helpful when
18:32
you want to view certain elements that are being hidden
18:36
by the architectural and you want
18:38
to see the skeleton of the model,
18:40
you will be able to do that.
18:42
So you can hide the objects in the current selection,
18:44
so that they are not drawn in the scene view this is useful
18:47
when you want to remove specific parts of the model.
18:51
And you can click on the Home tab and visibility panel
18:55
and hide or you can also use a command entry,
18:58
which is Control plus H which will
19:00
hide that particular object.
19:02
Let's say, for example, you select a particular object
19:05
and you press Control H and it will
19:07
be hidden so that you can see what is behind that.
19:11
So you will be able to do that using hide option,
19:15
and you can unhide the objects as well.
19:17
So let's say you have hidden it and then you want to unhide it,
19:20
you'll be able to do that.
19:22
You can hide all items except those currently selected,
19:26
so that they are not drawn in the scene view,
19:28
this is useful when you only want
19:29
to see specific parts of the model.
19:32
In the selection tree the items appear gray
19:34
when marked as hidden, so from the selection tree
19:37
you will be able to hide a few objects.
19:40
Let's say, for example, you want to hide the architecture
19:43
and structure and then you want to see just the MEP,
19:46
you will be able to do hide unselected option, which
19:50
is available in the Navisworks Home tab, Home tab, visibility
19:54
panel, hide unselected.
19:55
Whatever is not selected will be completely hidden in the view,
19:59
so you do have a good view of what are the elements that you
20:02
want to see.
20:04
Reveal selected objects, you can reveal a selection of objects
20:07
that are hidden, because you can select the objects
20:10
in the scene view you need to select them
20:12
in the selection tree.
20:13
Let's say, few of the objects that are hidden
20:15
and then you want to bring them back
20:17
you will be able to reveal those objects, which are selected
20:21
in the selection tree.
20:22
And then reveal all hidden objects,
20:24
so that is an option in Navisworks visibility
20:27
panel, which says unhide all.
20:30
When you unhide all and nothing is hidden everything
20:32
comes back to its previous view, so no objects will be hidden.
20:37
And sectioning plane and box, so click viewpoint tab,
20:43
sectioning panel and enable sectioning.
20:45
So we saw this in the demo as well,
20:47
that you can click on sectioning and then you
20:50
can click on the different gizmos that are available.
20:53
And Autodesk Navisworks opens the sectioning tools
20:56
tab on the ribbon and draws a section plane
20:58
through the model in the scene view.
21:00
And you will be able to leverage and view the section
21:05
and as mentioned, you will be able to choose
21:07
between plane and a box.
21:09
And so the box is now officially present on the screen in the B
21:14
image and with the move gizmo enabled by default.
21:18
So you can use both of these options.
21:22
So let's look at a demo video of controlling the visibility,
21:26
so you go to the selection tree you can just click it
21:29
and then you can say hide, which is available in the item tools,
21:32
so it's hidden then you can see the inside of the model.
21:39
And you can also say hide unselected,
21:40
since only that wall is selected when you did
21:43
hide unselected it unselected--
21:46
they just hidden whatever is unselected, right?
21:49
And then you click on unhide all and then
21:51
it brought back everything.
21:53
And then there is a couple of ways to do this one,
21:56
so we did that directly using the item tools
21:59
or in the selection tree you can just
22:00
click on it and right click and then say hide.
22:03
So there is quite a few ways you can hide and unhide
22:06
objects in Navisworks.
22:08
So as you've seen here, either you
22:10
want to do it in the selection tree it's possible,
22:12
or either you want to just right click that element
22:15
and say hide, even that is possible as well.
22:18
The next important feature that we will be talking about
22:21
is creating viewpoints and markups.
22:25
So in Navisworks you will be able to create viewpoints,
22:29
which enables you to add annotations to the viewpoints
22:34
and clash detection results.
22:36
So when you say viewpoints, you can
22:38
create folders as well as shown in the image B,
22:41
you can have like architectural structure and maybe folders.
22:44
And you can create these viewpoints
22:46
and place them under the folders.
22:48
The benefit of the viewpoints is that, let's say, you
22:51
have created a couple of viewpoints,
22:53
then it'll be easier for you to just directly go
22:55
to that particular viewpoint when
22:57
you want to share your findings with the other users,
22:60
instead of scrolling down to that particular point
23:02
every time.
23:03
So viewpoints helps in that way that you
23:06
have a snapshot of the different issues,
23:10
that you want to review with the team members
23:11
and you will be able to save those viewpoints in Navisworks.
23:16
So you click on viewpoint tab and then
23:18
you can save those viewpoints, and then
23:21
either directly over there or right-click
23:24
in the same viewpoints and then again you
23:26
can click on save your point.
23:27
So there are two ways that you will be able to do that.
23:30
As you can see over here, along the save viewpoint,
23:34
there are a few more options that are available in,
23:37
let's say, for example, if you want
23:38
to create a new folder within this one with a specific date
23:41
you will still be able to do that.
23:44
Let's look at the viewpoints demo in this video.
23:48
So let's say you can create--
23:50
so I have created a viewpoint over here,
23:52
which is let's say, door view one
23:55
and then you scroll the model and then
23:58
you create another viewpoint, let's say door view two.
24:03
So in this case, there are two viewpoints, right?
24:05
So it has created a snapshot and then
24:09
you can switch between these two views, view one and view two,
24:13
then you will be able to look at from that particular angle.
24:17
And again you can go inside and start
24:19
orbiting from that specific view,
24:22
but this snapshot itself doesn't change as soon as you
24:26
create that viewpoint.
24:27
It just stays at that particular location
24:30
looking at the certain way that you have decided when
24:33
you have created the viewpoint.
24:35
So with the viewpoints, you will be
24:37
able to use the review features that are
24:39
available in the Navisworks.
24:42
So when you go to review there are
24:43
a couple of options that is being provided to you.
24:46
So the first one is measurements,
24:48
you will be able to measure between the two
24:51
elements in Navisworks.
24:52
And you red line it and then highlight it.
24:57
And you can add tags over there, and also you
25:00
can add comments as well.
25:02
So if the viewpoint was not saved it,
25:05
a new viewpoint will be created.
25:08
So if there is no viewpoints that you have saved,
25:11
a new viewpoint will be created when
25:14
you do the reviews and markups, so they can stay on a viewpoint
25:19
only.
25:20
So when using the lock, select None
25:22
to reset the reference plane.
25:24
Over here in this picture, as you can see the red line
25:28
markings are done and the measurement is shown.
25:31
And then you can also do a couple of notes over here
25:35
let's say, for example, if you want to say I conveyed this
25:38
to the team members to add a column here,
25:39
and column missing that you'll be
25:41
able to do that using the reviews.
25:44
And you can tag and comments will
25:46
provide additional information to manage that review process.
25:49
So in that particular view, you'll be able to tag.
25:52
You can add the date, author, comment ID and status.
25:56
You will be able to do that and also
25:58
use the find comments window or to set up and run
26:00
a search for tags and comments based on the metadata.
26:05
So from the comments section find and you can run reports
26:10
on what are the items that are modified between a certain date
26:13
to a certain date, that you will be able to get
26:15
that list from there.
26:17
And use the controls on the Tags panel
26:20
to navigate through the tags, so you
26:23
can navigate through the tags using this tags
26:26
option over here.
26:27
So let's look at the markups demo, so I click on review
26:31
and then when you click on review,
26:32
you have a couple of options such as line or a revision
26:35
cloud, so you'll be able to do that.
26:38
You can start drawing directly in that particular view.
26:43
And then you can click on measure
26:45
and you can lock the access as well, so
26:47
that the access doesn't move.
26:49
So you can click on perpendicular
26:52
and then check, OK, what is the distance between those two
26:56
columns?
26:56
And it would be highlighted.
26:58
First it highlights unless you click it
27:00
on convert to red line, then it gets converted to the red line.
27:05
Again you can convert it to red line
27:06
and it shows the dimensions between that,
27:10
and then you can put a revision cloud
27:13
or add further comments to that particular view.
27:23
So you can add the text over there,
27:27
and then you can add an arrow pointing
27:29
to that particular location.
27:34
So once you have done you can rename that as per you
27:40
want to rename it and even you can move it
27:42
inside the different folders, depending
27:44
on who needs to take action based on the comments that
27:48
is provided.
27:49
You click on that, you can further
27:51
add more description rather than just adding all the description
27:56
directly in the view, you'll be able to further add
27:59
more description on when the stakeholders looking at it,
28:03
they will be able to look at this comment
28:05
and then make the changes accordingly.
28:07
So you can add those comments you click on view comments
28:09
and you will be able to see those comments that
28:13
has been provided for that particular viewpoint.
28:17
And you will be able to search between the different dates
28:21
on the different review items that has been created,
28:29
and you'll be able to also click on tags to go over item
28:34
by item.
28:35
So this is very useful, when you want
28:37
to communicate more information to the different stakeholders
28:41
in your coordination meeting.
28:42
Other than just a viewpoint, you can further
28:44
add more of these reviews and convey those information
28:49
to them, so that you'll be able to come
28:51
to an effective resolution.
28:54
The last part that we'll be covering in this lecture
28:57
is running the clash detector between the trades, which
29:01
is one of the powerful feature of Navisworks.
29:05
So running the clash directive between trades and Navisworks
29:08
provides more options and control over your clash test
29:12
in comparison to Glue, and under the Home tab select clash
29:16
detective, so you can go in the Home tab
29:19
and you will see a particular button, which
29:22
is called the clash detector.
29:24
When you click on that, then you will get the items
29:28
B and C pop up in your screen.
29:30
So you will get the screen and if you
29:32
have dual monitors it is even better
29:35
you can take these clash detector screens
29:38
instead of overlaying to a different screen.
29:41
So once you have done that, you will need to add the tests,
29:45
so in item C it shows all the tests that are there,
29:48
when you see the B, right?
29:50
In image B there is something called as add test.
29:53
So you'll be able to keep adding tests over there.
29:56
So let's say you want to test or check between architecture
30:00
and structure, so you click on add test,
30:02
let's say you want to check between the structure
30:04
and the mechanical you click on add test.
30:06
So you keep adding these tests let's
30:09
say, for example as per your record
30:10
I recommend maybe you have 10 to 12 tests.
30:13
So you will see the entire list in the C image, which
30:17
is shown over there, so you clicked on a test
30:19
and you will see all of that.
30:20
And also you will see two columns
30:23
over there one is selection A and selection B,
30:26
and in selection A it shows all of the models and WC's that
30:31
are appended to the file and same it is shown
30:35
and the selection B as well.
30:38
Now, you'll be able to select, let's say architecture
30:41
in selection A and structure in selection B
30:44
and then you will be able to run a test between those.
30:47
Or you can select MEP in selection A and structure
30:51
in selection B and you will be able to run the test.
30:55
So whatever you are selecting, you
30:56
can give the specific name in the test.
30:60
Let's say if you want to clash between MEP
31:02
and structure for that particular test
31:05
you have the name as MEP versus structure or MEP
31:08
underscore structure, so that you are clear on what
31:11
is clashing between the two whenever you come back
31:14
to the work in progress model.
31:16
To choose the elements to test, so you
31:19
can choose between the different elements,
31:22
let's say, for example you want to clash
31:23
between the first floor architecture
31:26
versus the first floor structure,
31:27
so you will be able to select that.
31:29
And you can also provide a tolerance in the settings,
31:33
let's say you want Navisworks to ignore
31:37
the clash for that particular MM, you can mention that.
31:41
And once you have mentioned that,
31:42
Navisworks will ignore that based on the tolerance.
31:46
For example, if there is an insulation in the pipe and then
31:50
you want to ignore it, so you'll be
31:51
able to set those tolerance in this case.
31:53
And there are different clash types
31:55
that you will be able to select, hard, hard conservative,
31:59
clearance, and duplicates.
32:01
So you'll be able to choose between these different types.
32:05
Hard shows all the hard clashes, hard conservative
32:08
shows even a slightest touch of any triangulations
32:12
that happen in the software.
32:13
Even if elements are running parallel and even the slightest
32:16
touch will be highlighted in hard conservative,
32:20
and clearance for if you want to check any clearance.
32:23
And if you want to check for any duplicates in the model,
32:26
so you'll be able to choose their duplicates clash type.
32:29
And once you have selected that, then you
32:31
will be able to run the test.
32:33
So once you have run the test, so be there in the select tab.
32:38
So we were in the select Tab over here.
32:40
So when you click on Run test only after that the Results
32:45
tab get populated, and then when you click on the results tab
32:49
you will see this interface of all the clashes
32:51
that you can see.
32:52
So once that test has been run you
32:55
will find a significant number of clashes,
32:57
so this can now be grouped up and distributed via Glue
32:60
to allow other team members to view and rectify.
33:03
And if you're using BIM 360 Glue you
33:05
will be able to connect to BIM 360 Glue.
33:07
And Navisworks you will be able to group these clashes
33:11
and assign it to the right team members using viewpoints,
33:16
so that is possible as well.
33:17
So you can group clashes either by selecting
33:20
multiple related clashes or clicking on New group.
33:23
So either you can say click on New group
33:26
or multiple related clashes.
33:28
You can select those clashes and then click on create group.
33:31
So the reason we are grouping the clashes is because you
33:35
may have a lot of clashes, but then when you are looking
33:38
at the issues, so a couple of clashes
33:40
can be combined to a single issue.
33:42
This way you can make it like each group
33:45
is an issue that needs to be addressed,
33:47
rather than going into each clash
33:49
and assigning it to different users.
33:51
So it's always better if a group of these clashes
33:55
can be bundled up as a single issue.
33:57
You will need to do that in Navisworks,
33:60
so that they can be bundled and looked at as a single issue
34:03
to be actioned upon.
34:04
And the most common way of grouping clashes is by item.
34:07
The item windows at the bottom shows
34:09
what elements are clashing, select group
34:11
clashes involving item.
34:13
So in the item you will also see further details, as well
34:18
on what is clashing with what.
34:20
And similarly you will be able to see that in the view
34:23
as well, so you can go looking at the view
34:26
and then grouping the clashes as well.
34:28
So if you want to create views that
34:30
track the progress of coordination in an area,
34:32
set the highlighting to use status color each time
34:35
you run this report.
34:37
And repeat this step until you're done grouping clashes.
34:41
And also there are few options that are available where you
34:45
can dim other or hide other .
34:46
So let's say you have selected clash five,
34:49
when you click on Dim other, the other elements
34:52
will be in a ghosted mode.
34:53
However, when you click on hide other,
34:55
you will see only these two elements clash
34:58
of what is clashing with what.
35:00
So once you have grouped that, you
35:02
do have an option in the tab of the reports tab,
35:06
you will be able to create reports.
35:08
There are quite a few options that you can do,
35:11
whether it is group headers only or individual clashes
35:14
or everything.
35:15
And then as well can filter it based
35:17
on, whether you want to create the report just
35:20
for the new clashes, active clashes
35:22
or reviewed, approved or resolved,
35:24
you'll be able to further filter down
35:26
depending on how you want to get that report.
35:29
And then the report format, so you can either
35:33
have an HTML format or you can have it as a viewpoints.
35:37
So whatever clashes that you have identified
35:39
can be saved as a viewpoint in a report format,
35:43
so you click on write a report and they will
35:45
be saved as the viewpoints.
35:49
So let's look at the clash detection demo video.
35:52
So you click on the clash detective tab,
35:55
and then this particular tab opens up and you can pin it
35:60
and that's called test one.
36:03
So you can change it to the name of your choice, which
36:08
makes more sense for you to understand
36:11
what is clashing with what.
36:12
So we have selected MEP first-floor and the structure
36:15
first-floor.
36:17
So that the next is a hard clash, so run report then
36:21
it is going to show you like all of these clashes.
36:25
And since it is Dim other, it is actually
36:28
making the other elements transparent
36:29
and you can review all of these clashes over here.
36:36
And you can select a few clashes and then
36:42
you put them under the single group.
36:48
You can work on a resolution for that particular issue
36:53
and you can give a specific name to that.
37:00
And then you can choose the colors between that,
37:04
so when you select item colors it
37:07
will highlight between red and green.
37:10
So you will be aware of these two elements, what
37:13
is clashing with what.
37:14
And when you click on hide other,
37:15
the other elements would be hidden
37:17
and when you come out of the Dim other
37:19
you will see the entire model as well.
37:30
When you go to the Report tab, you
37:32
will be able to run the report and let's say, for example we
37:37
want to write a report in the HTML format,
37:40
so you can save the report in the HTML format.
37:44
And once that report is written you,
37:46
will get this report, which you will
37:48
be able to share with the different users.
37:52
It gives a snapshot of that clash, the name, distance,
37:56
description, flash point and date created.
37:59
And when you click on that image it gets bigger,
38:01
as well for you to review those flashes.
38:05
Thank you everyone.
