Work with categories

Understand and work with categories.


00:04

Each

00:04

that is placed into a rivet project will have a category,

00:08

the required categories defined in the family editor and

00:11

would automatically configure built in parameters and other options.

00:15

Relevant to that category.

00:18

In the example of the pile caps and piles,

00:20

the built in parameters will control the length, width and foundation thickness.

00:25

Whereas the beam will have the categories for structural framing applied.

00:29

And hence, we have a number of parameters to configure the ice section.

00:33

These would include the dimensions of the beam as

00:35

well as parameters to control the structural analysis.

00:39

If you are using a generic family template,

00:41

it is best practiced to set the category before creating additional parameters.

00:48

Let's now take a deeper look at family categories and parameters

00:52

on the creates ribbon. Go ahead and select family category and parameters.

00:57

You may remember that we switched our

00:59

category from generic model to structural foundation

01:03

when we did this rev it automatically created

01:05

built in parameters to support structural foundations.

01:09

But you'll also notice there's some family parameters that

01:11

we can also configure in this dialog box.

01:15

So we'll see things like workplace based,

01:17

always vertical.

01:19

And another one, we're going to set here is material for model behavior.

01:24

This is quite an important setting within the structural context.

01:28

This controls how elements join.

01:31

So for example, if we have a steel beam coming up to a column,

01:35

there'll be naturally a gap between that it won't physically join.

01:39

And the same would be true for precast and also timber.

01:42

However, if that was set to concrete,

01:45

the object would then be able to merge together and form a monolithic structure.

01:49

So this defines how the family will join

01:51

to other families in the project environment.

01:55

In this case here, we want to set this to concrete because of course,

01:58

this is cast in place concrete.

02:01

Let's go ahead and select, OK. To family category and parameters,

02:06

we can now continue by setting up our parametric framework

02:10

on the create ribbon.

02:11

Let's start by selecting reference plane

02:16

on the draw panel, I'll go ahead here and select pick lines

02:20

and on the options bar. I'm going to set my offset to 3 ft.

02:26

We can then go over to the vertical reference

02:28

plane and create an offset to the left hand side

02:31

and an offset to the right

02:34

move over the horizontal plane

02:35

and create an offset to the top

02:38

and also an offset to the bottom.

02:41

Let's now release the command by clicking, modify or pressing escape.

02:46

We'll now set up aligned dimensions and make those equal

02:50

as a recap.

02:51

What you'll notice is if we select the two center planes here,

02:54

they are pinned and they define the origin of this family.

02:58

So these can't move these ones here, of course, can move.

03:03

So let's now go ahead and create the aligned dimensions.

03:07

Click the annotate ribbon and then select aligned.

03:11

I'm going to begin by placing the line

03:13

dimensions on these three vertical reference points,

03:17

place them down and then select EQ

03:20

we'll do the same for the three horizontal planes,

03:24

place them down. And again, select EQ

03:29

if we then press escape or select, modify,

03:32

we can now test this. If I select this reference plane on the left hand side,

03:37

I'm just going to hold down the shift key and press the

03:40

right hand arrow or the left hand arrow key on the keyboard.

03:44

And you can see we are now flexing this family

03:48

notice as I move the reference plane to the left and the right,

03:52

the center plane is staying static because it's pinned

03:55

and the EQ dimension there is forcing the right hand plane to move at the same rate.

04:01

So I have symmetry around this.

04:04

And of course, if I do the same for this particular plane here,

04:07

hold the shift key down.

04:09

And this time I'm going to use the up and down arrow keys.

04:12

Again, you can see that changing.

04:17

So we now assign our parameters to these reference planes.

04:22

Let's go and select the annotate ribbon. And again, select aligned dimension

04:28

I'll place in a line dimension here.

04:30

This is going to control the length of the foundation

04:33

and another one here which will control the width.

04:38

We'll go ahead and select, modify or press escape.

04:42

And now if I select this dimension here

04:45

on the context driven, you'll notice we have label dimension.

04:49

Now here, I'll need to create a new parameter.

04:52

So I'll select create parameter.

04:55

And you'll see now we're in the parameter properties dialogue.

04:59

Now, of course, in this video, we are using shared parameters.

05:02

So we'll select the shared parameter option

05:04

and then go ahead and select our shared parameter

05:08

here. You can see that we have our shared parameters that we created earlier.

05:11

And I'm looking here for F length. So we can select, OK,

05:16

notice now that we've assigned this,

05:18

that all these areas are grayed out because

05:20

this is defined in the shared parameter file.

05:22

And we're gonna group this under dimensions.

05:25

Let's go ahead and click. OK.

05:29

We did a similar thing for the width.

05:31

So again, on the ribbon, we can select to create parameter,

05:36

select shared parameter,

05:38

go ahead and select that shared parameter. In this case, it's F width.

05:44

Again, it's going to be a T parameter.

05:46

And all of this is defined in the shared

05:48

parameter file and we'll group this under dimensions.

05:52

And finally, here we'll think about the thickness of our foundation

05:56

to do that in the project browser. We'll go ahead and open up front innovation.

06:02

The reference level is the top of my foundation.

06:06

So I'm going to need to create an additional

06:07

reference plane to set the underside of the foundation

06:11

to do that. I'll go ahead and select the create ribbon

06:14

and select reference point.

06:17

And here I can now create my new reference plane.

06:25

I'm then going to select the annotate ribbon and click aligned dimension.

06:30

We place our dimension.

06:34

I'll select, modify, I'll press escape.

06:37

And once again, I'll create a new parameter

06:39

and assign that to my shared parameter that's

06:42

gonna control the thickness of the foundation.

06:45

So up on the context ribbon, we can select create parameter

06:50

here. We can set up the shared parameter option

06:55

and go ahead and select F thickness

06:58

again. All the settings will stay the same in here

07:01

and click. OK.

07:04

So we now have all of our shared parameters configured and set up.

07:10

We'll now switch back to our ref level.

07:12

We can now physically define the geometry for our pad foundation

07:16

to do this. We can select and create ribbon

07:19

on the create ribbon. I'll select extrusion

07:24

on the context ribbon in the draw panel.

07:26

In this example, I'm going to select rectangle

07:30

and we'll then sketch the rectangle around these reference planes.

07:36

It's very important that we constrain these lines.

07:40

So what's now happening is each of these four

07:42

lines is now constrained to those reference planes.

07:46

I'll then go up to the context ribbon and select finish edit mode.

07:53

We'll open up our front elevation.

07:56

Here's our extrusion if I select the extrusion,

07:60

I'm going to use the shape handles here

08:02

just to control the start and end position vertically for this extrusion.

08:08

So here I can drag this down

08:10

and notice it will then snap onto the reference level

08:14

and I can again constrain that

08:17

I'll do the same for the lower shape handle.

08:20

Again, I've constrained it here

08:22

and I must block the padlock to constrain the extrusion

08:26

to the reference plane.

08:30

We can now test this in the project environment.

08:33

So up on the ribbon, let's go ahead and select load into project and close.

08:38

I'll click. Yes, to save changes to my pad foundation

08:44

again here. You'll notice. Now we're in level two.

08:48

Ideally, I'd want to place this on level one.

08:50

So in the project browser, we'll just double click on structural plans,

08:53

level one to open this up.

08:56

So we now have to go ahead and create our foundation.

08:59

So let's go ahead and select the structure ribbon

09:02

on the structure ribbon. We'll select isolated foundation

09:07

notice in the properties pallet.

09:09

In our type selector, we have our pad foundation active.

09:12

If I move my cursor into the model here,

09:15

we can then go ahead and place down these foundations.

00:04

Each

00:04

that is placed into a rivet project will have a category,

00:08

the required categories defined in the family editor and

00:11

would automatically configure built in parameters and other options.

00:15

Relevant to that category.

00:18

In the example of the pile caps and piles,

00:20

the built in parameters will control the length, width and foundation thickness.

00:25

Whereas the beam will have the categories for structural framing applied.

00:29

And hence, we have a number of parameters to configure the ice section.

00:33

These would include the dimensions of the beam as

00:35

well as parameters to control the structural analysis.

00:39

If you are using a generic family template,

00:41

it is best practiced to set the category before creating additional parameters.

00:48

Let's now take a deeper look at family categories and parameters

00:52

on the creates ribbon. Go ahead and select family category and parameters.

00:57

You may remember that we switched our

00:59

category from generic model to structural foundation

01:03

when we did this rev it automatically created

01:05

built in parameters to support structural foundations.

01:09

But you'll also notice there's some family parameters that

01:11

we can also configure in this dialog box.

01:15

So we'll see things like workplace based,

01:17

always vertical.

01:19

And another one, we're going to set here is material for model behavior.

01:24

This is quite an important setting within the structural context.

01:28

This controls how elements join.

01:31

So for example, if we have a steel beam coming up to a column,

01:35

there'll be naturally a gap between that it won't physically join.

01:39

And the same would be true for precast and also timber.

01:42

However, if that was set to concrete,

01:45

the object would then be able to merge together and form a monolithic structure.

01:49

So this defines how the family will join

01:51

to other families in the project environment.

01:55

In this case here, we want to set this to concrete because of course,

01:58

this is cast in place concrete.

02:01

Let's go ahead and select, OK. To family category and parameters,

02:06

we can now continue by setting up our parametric framework

02:10

on the create ribbon.

02:11

Let's start by selecting reference plane

02:16

on the draw panel, I'll go ahead here and select pick lines

02:20

and on the options bar. I'm going to set my offset to 3 ft.

02:26

We can then go over to the vertical reference

02:28

plane and create an offset to the left hand side

02:31

and an offset to the right

02:34

move over the horizontal plane

02:35

and create an offset to the top

02:38

and also an offset to the bottom.

02:41

Let's now release the command by clicking, modify or pressing escape.

02:46

We'll now set up aligned dimensions and make those equal

02:50

as a recap.

02:51

What you'll notice is if we select the two center planes here,

02:54

they are pinned and they define the origin of this family.

02:58

So these can't move these ones here, of course, can move.

03:03

So let's now go ahead and create the aligned dimensions.

03:07

Click the annotate ribbon and then select aligned.

03:11

I'm going to begin by placing the line

03:13

dimensions on these three vertical reference points,

03:17

place them down and then select EQ

03:20

we'll do the same for the three horizontal planes,

03:24

place them down. And again, select EQ

03:29

if we then press escape or select, modify,

03:32

we can now test this. If I select this reference plane on the left hand side,

03:37

I'm just going to hold down the shift key and press the

03:40

right hand arrow or the left hand arrow key on the keyboard.

03:44

And you can see we are now flexing this family

03:48

notice as I move the reference plane to the left and the right,

03:52

the center plane is staying static because it's pinned

03:55

and the EQ dimension there is forcing the right hand plane to move at the same rate.

04:01

So I have symmetry around this.

04:04

And of course, if I do the same for this particular plane here,

04:07

hold the shift key down.

04:09

And this time I'm going to use the up and down arrow keys.

04:12

Again, you can see that changing.

04:17

So we now assign our parameters to these reference planes.

04:22

Let's go and select the annotate ribbon. And again, select aligned dimension

04:28

I'll place in a line dimension here.

04:30

This is going to control the length of the foundation

04:33

and another one here which will control the width.

04:38

We'll go ahead and select, modify or press escape.

04:42

And now if I select this dimension here

04:45

on the context driven, you'll notice we have label dimension.

04:49

Now here, I'll need to create a new parameter.

04:52

So I'll select create parameter.

04:55

And you'll see now we're in the parameter properties dialogue.

04:59

Now, of course, in this video, we are using shared parameters.

05:02

So we'll select the shared parameter option

05:04

and then go ahead and select our shared parameter

05:08

here. You can see that we have our shared parameters that we created earlier.

05:11

And I'm looking here for F length. So we can select, OK,

05:16

notice now that we've assigned this,

05:18

that all these areas are grayed out because

05:20

this is defined in the shared parameter file.

05:22

And we're gonna group this under dimensions.

05:25

Let's go ahead and click. OK.

05:29

We did a similar thing for the width.

05:31

So again, on the ribbon, we can select to create parameter,

05:36

select shared parameter,

05:38

go ahead and select that shared parameter. In this case, it's F width.

05:44

Again, it's going to be a T parameter.

05:46

And all of this is defined in the shared

05:48

parameter file and we'll group this under dimensions.

05:52

And finally, here we'll think about the thickness of our foundation

05:56

to do that in the project browser. We'll go ahead and open up front innovation.

06:02

The reference level is the top of my foundation.

06:06

So I'm going to need to create an additional

06:07

reference plane to set the underside of the foundation

06:11

to do that. I'll go ahead and select the create ribbon

06:14

and select reference point.

06:17

And here I can now create my new reference plane.

06:25

I'm then going to select the annotate ribbon and click aligned dimension.

06:30

We place our dimension.

06:34

I'll select, modify, I'll press escape.

06:37

And once again, I'll create a new parameter

06:39

and assign that to my shared parameter that's

06:42

gonna control the thickness of the foundation.

06:45

So up on the context ribbon, we can select create parameter

06:50

here. We can set up the shared parameter option

06:55

and go ahead and select F thickness

06:58

again. All the settings will stay the same in here

07:01

and click. OK.

07:04

So we now have all of our shared parameters configured and set up.

07:10

We'll now switch back to our ref level.

07:12

We can now physically define the geometry for our pad foundation

07:16

to do this. We can select and create ribbon

07:19

on the create ribbon. I'll select extrusion

07:24

on the context ribbon in the draw panel.

07:26

In this example, I'm going to select rectangle

07:30

and we'll then sketch the rectangle around these reference planes.

07:36

It's very important that we constrain these lines.

07:40

So what's now happening is each of these four

07:42

lines is now constrained to those reference planes.

07:46

I'll then go up to the context ribbon and select finish edit mode.

07:53

We'll open up our front elevation.

07:56

Here's our extrusion if I select the extrusion,

07:60

I'm going to use the shape handles here

08:02

just to control the start and end position vertically for this extrusion.

08:08

So here I can drag this down

08:10

and notice it will then snap onto the reference level

08:14

and I can again constrain that

08:17

I'll do the same for the lower shape handle.

08:20

Again, I've constrained it here

08:22

and I must block the padlock to constrain the extrusion

08:26

to the reference plane.

08:30

We can now test this in the project environment.

08:33

So up on the ribbon, let's go ahead and select load into project and close.

08:38

I'll click. Yes, to save changes to my pad foundation

08:44

again here. You'll notice. Now we're in level two.

08:48

Ideally, I'd want to place this on level one.

08:50

So in the project browser, we'll just double click on structural plans,

08:53

level one to open this up.

08:56

So we now have to go ahead and create our foundation.

08:59

So let's go ahead and select the structure ribbon

09:02

on the structure ribbon. We'll select isolated foundation

09:07

notice in the properties pallet.

09:09

In our type selector, we have our pad foundation active.

09:12

If I move my cursor into the model here,

09:15

we can then go ahead and place down these foundations.
