When working in Autodesk Point Layout, you can add clevis and trapeze hangers to pipe and conduit,
00:09
as well as strap and trapeze hangers to ductwork.
00:13
With a project open, right-click in the model space, and select Point Layout > Automated Location Pts.
00:23
On the Duct Hangers tab, note that all information located in the table can be changed,
00:28
and is arranged into Rectangular, Round, and Oval hanger shape tabs.
00:35
Expand the Hanger Spacing drop-down and pick a length.
00:40
Enter a start number, make sure Hanger Pts is enabled, and select Include Hanger Block.
00:50
You can also adjust offsets for specific components, such as insulation and fittings.
00:57
In the Selection Options group, enable Select Some, then click OK.
01:05
Select the objects you want to add hangers to, and press ENTER.
01:11
You are prompted to choose between setting the height of the hanger blocks to a set value, or to a specific elevation.
01:19
In this example, Set Elevation is chosen.
01:24
On the command line, enter a value of elevation for the hangers to extend to—in this case, 13 feet.
01:34
You will receive a notification that the hanger point placement is complete.
01:41
Zoom to the objects you selected, and you can see the added hangers.
01:48
Note that all hangers created in Point Editor are editable.
01:52
You can open them in the Block Editor and change any values.
01:58
Now, repeat the process with pipes.
02:03
Reopen the Autodesk Point Layout dialog, and this time, select the Pipe Hangers tab, which works like the Duct Hangers tab.
02:12
Enter a Start Number, enable Pipe Hanger Pts, enable Select Some, and then click OK.
02:23
Select the pipes you want to add hangers to, and then press ENTER.
02:29
Again, assign the hanger blocks a set elevation or height.
02:36
To add trapeze hangers across spans, return to the Autodesk Point Layout dialog, and this time, enable Manual Placement.
02:47
Change any values necessary, make sure that Select Some is still enabled, and then click OK.
02:55
On the command line, type “T” (for trapeze), and then press ENTER.
03:03
You are prompted to select the object the hangers should start at, and then, to enter a value for their elevation or height.
03:12
In this example, a piece of pipe is selected, and then an elevation of 20 feet is entered.
03:21
Zoom to the span where the hanger will connect, and pick the left and right extents—start points A and B, respectively.
03:31
On the command line, you can enter a rod size, insulation thickness, and an offset value—in this case, a value of 8 is entered.
03:43
You can also adjust the override width and hanger point spacing, which is set here to 48 inches.
03:51
As you move your cursor around the model, you see hangers being created.
03:57
Any time you press and hold CTRL, a hanger is created at the location of your cursor to break the command.
04:05
Click when you are satisfied with the hanger placement.
04:10
The hanger block for the trapeze is inserted, and points are created at the top of the rod.
04:17
Note that Point Layout creates these A and B points as siblings.
04:22
In this case, you see that the object numbers 7017 and 7017.1 are part of the same hanger system.
04:34
You can repeat this process for electrical conduit, by returning to the Autodesk Point Layout dialog and selecting the Electrical tab.
04:44
From here, follow the same steps as you did on the Pipe Hangers tab.
04:54
On the Block Options tab, you can find further customization options for hangers,
04:60
including the Hanger Scale, Hanger Block Layer, Text Height, and Point Role.
05:08
Next to the Custom Block Adder field, click Browse (...) to add and insert custom blocks.
05:16
You can also choose to disable sibling point decimals,
05:20
use a two-level trapeze block, and set the second-level distance from the bottom of the run.
05:27
In this case, click Cancel to close the dialog.
05:33
To set custom hanger heights, right-click and select Point Layout > Tools > Set Hanger Block Heights.
05:42
You are asked if you want to select GTP hanger blocks only on specific layers.
05:48
In this case, click Yes.
05:53
In the Select Layers dialog, select the Select All/None checkbox, then click OK.
06:01
Now, select some hangers in your project, and in this case, choose Set Elevation.
06:10
On the command line, you can see that these hangers currently extend to 23 feet.
06:16
Set it to 26 feet, and then press Enter.
06:21
The hanger heights are now adjusted to the new elevation.
