NARRATOR: Modeling cable tray horizontally

00:02

on a wall in Revit.

00:04

In this video, we're going to show you

00:06

how to get cable tray and cable tray

00:08

fittings to work when the tray is running horizontally.

00:13

I'm in the Small Medical Center project in the electrical room

00:16

South wall section view facing the panels.

00:20

You can see the vertical cable tray

00:22

that was added in the previous video.

00:25

But what if you want to place cable tray horizontally

00:28

on a wall?

00:29

This is a bit more complex.

00:32

So I'm going to start the cable tray command in systems

00:36

electrical fittings, and I'm going to draw a cable

00:40

tray horizontally.

00:43

Now the width is always seen as the value visible in plan

00:47

and the height in elevation.

00:50

If I try to rotate this cable tray,

00:52

it'll only rotate around the same axis,

00:55

but it's not going to rotate to flat against the wall.

00:59

So I'm going to delete the cable tray.

01:02

If we want to have the cable tray run

01:04

horizontally but on edge, we need to use a workaround.

01:08

Basically, we're going to copy the vertical cable tray

01:11

and then rotate it.

01:13

So I've copied it once, I'm going

01:15

to copy it again because I want another vertical one.

01:18

I go to the rotate command and I'm

01:20

going to rotate this 90 degrees.

01:24

And now I can drag it into position.

01:26

Before I go further, I'm going to nudge the cable

01:29

tray along the right wall over a little bit.

01:32

I'm using arrow keys on the keyboard to do this.

01:36

Now watch out because a lot of standard commands

01:38

that work fine in plan do not work with horizontal cable

01:42

tray.

01:43

If I try to use the connectors by dragging control

01:46

from the horizontal to the vertical cable tray,

01:49

it rotates back to the way the program wants it to be.

01:52

And there's an additional error, so I'm going to undo that.

01:56

So instead of using the connectors,

01:58

I'm going to change the length using temporary dimensions.

02:02

So I want this to be six feet.

02:04

I can go ahead and use the connectors

02:07

on the vertical cable tray and it does work just fine.

02:12

Now let's try adding a fitting.

02:16

In the Systems tab on the electrical panel,

02:18

I'm clicking Cable tray fitting.

02:21

In the type selector, I'm selecting the ladder horizontal

02:25

bend standard.

02:27

Now if I try to place it on the cable tray,

02:30

you can see it comes in but it's facing the wrong way.

02:34

If I try it on the vertical one it

02:36

looks fine but then when I actually place

02:38

it puts it on the opposite end.

02:42

So I'm going to delete this one out.

02:44

What I have to do instead is place the cable tray then

02:48

use the rotate controls to move it around until it's

02:52

facing the right way.

02:54

This does take a little bit of time, and you see,

02:56

I'm choosing a bunch of different ones

02:57

here until I finally get it rotated as I'm expecting.

03:02

Now I'm going to use a regular rotate command

03:05

to get it to face the direction I want it to face.

03:12

And then I realize, Oh no it's not showing the ladders.

03:16

So let me just make it the right size first

03:19

and I'm going to make that the right size,

03:20

and I'm going to use the rotate commands again

03:23

to get it into the right place.

03:26

So there it is showing the ladder,

03:28

and finally one more time I'm going

03:30

to rotate it and make sure it's facing the right direction.

03:39

And now I'm going to move it into place.

03:41

But just like the other situations

03:42

I don't want to move it into place using the connectors.

03:46

So if I come in here and try it out with the vertical one.

03:50

So sometimes you think Oh, the controls work on the vertical.

03:53

But if I Zoom in here and move the control on the vertical

03:57

and connect them, I get an error.

03:60

So I'm going to need to cancel that and then just use

04:03

the Nudge command, the arrow keys to get it into place

04:06

without touching the connector.

04:12

Now on the other end of the cable tray

04:14

I want a horizontal to a T coming into the vertical.

04:19

So in the Systems tab, I'm selecting cable tray,

04:22

and then I'm using the ladder horizontal T

04:26

at a 12 inch radius.

04:28

Once again, I can't put it into the cable tray automatically.

04:33

So I'm going to place it, click Modify, and then use

04:36

the rotate commands once again finding the right direction.

04:40

There it is.

04:41

Still not quite right because it's not showing the ladder.

04:48

Now let's make sure the fitting is the right size on each end,

04:51

I'm making that 12 inches.

04:55

And then I'm going to drag it to the correct location.

04:58

Can use alignment lines, but again, remember

05:00

don't use controls to do this.

05:04

I'm going to nudge the cable tray,

05:05

the horizontal cable tray into place

05:09

so it's closer to the fitting.

05:12

Then I'm going to split the vertical cable tray.

05:15

So in Modify I click Split.

05:18

I'm selecting two points along the cable tray.

05:22

I do get a warning in this case.

05:24

So I am deleting the elements.

05:26

I'd want that deleted out anyway.

05:28

And now you can see I have my cable tray fittings,

05:32

they're all in the right location not quite exact.

05:36

So I'm going to make this a little bit longer.

05:38

I'm going to make the 6 foot

05:42

it fit a little bit better.

05:44

Now I have my individual pieces of cable tray

05:47

and the separate cable tray fittings.

05:49

I can move them around and resize

05:51

them using temporary dimensions to get them into place.

05:55

By doing this you get an accurate take off of cable tray

05:58

and fittings in your schedules.

Model a cable tray horizontally on a wall in Revit - Exercise

Open the Small Medical Center-Cable Tray Horizontal.rvt project. You are in the Electrical Room South Wall section view, facing the panels. You can see the vertical cable tray that was added in the previous practice.
Start the Cable Tray command and draw a cable tray horizontally. Width is always seen as the value visible in plan and height in elevation.
Delete the horizontal cable tray.
Copy the vertical cable tray twice, as shown below.
Rotate the middle cable tray 90° and drag it into position above the electrical panels, as shown below. (Do not use controls.)
Nudge the vertical cable tray along the right wall over closer to the walls. This is done by selecting the element and using the arrow keys on the keyboard.
Many standard commands that work fine in plan do not work on the horizontal cable tray. For example, if you try to use the connectors, by dragging the control from the horizontal cable tray to the vertical cable tray. It rotates it back to the way the program wants it to be and there is an additional error.
Click Undo.
Select the horizontal cable tray and change the length using the temporary dimension to 6'-0".
The vertical cable tray can be modified using the control. Drag it down some so the model looks similar to the example below.
In the Systems tab > Electrical panel, click Cable Tray Fitting.
In the Type Selector, select Ladder Horizontal Bend: Standard.
Hover over the left end of the horizontal tray. It can be placed here but it will not go in the direction needed, as shown below.
Hover over the top of the vertical cable tray and it looks like it is going to be placed as expected, as shown below.
Click to place the fitting and it places it at the other end facing the wrong direction, as shown below.
Delete the fitting.
Start the Cable Tray Fitting command again and place the fitting in the view where it isn't touching anything.
Use the rotate controls on the fitting to rotate it around until you see the ladder side, as shown below.
Use the Rotate command to rotate it to the correct direction.
Use the Width control and set the Width to 12", as shown below.
Drag the fitting in to place but do not use connectors.
Nudge the elements into place using the keyboard arrows.
In the Systems tab> Electrical panel click Cable Tray Fitting.
In the Type Selector, select Ladder Horizontal Tee: 12" Radius.
Place the fitting away from the cable tray and use the rotate controls and the Rotate command to get it facing the right way. Make sure you see the ladder.
Change the Width controls to 12", as shown below.
Drag the fitting to the correct location over the vertical cable tray and in alignment with the horizontal cable tray, as shown below.
In the Modify tab > Modify panel, click Split.
Click two points along the vertical cable tray. If a warning displays, click Delete Elements. Make sure the split cable tray is removed.
You can now nudge the individual cable trays and fittings into place and change the length using temporary dimensions.
By adding in cable tray that rests against a wall, you can have an accurate takeoff of cable tray and fittings in your schedules.
Save the project.
