Cable Tray connections vertical

[d_spigolon]

The main cable tray backbone will be installed in the building's four-story shaft. From it, a dedicated floor cable tray will branch out at each level.

However, the software is unable to generate a vertical "T" connection. Can anyone help me?

Is there a suitable tee family in your routing preferences?

What would the connection look like in real life = would the horizontal runs not just start with a downward looking bend so that cables can sweep onto them from the vertical run?

I would like to repeat number 17.

Vertical down tee

You would need to find or create a suitable Revit family, maybe from a manufacturer's BIM content?

I got a reasonable approximation just by creating the horizontal, and then one elbow by making a vertical.  Then I drug the riser past the bend, and in a section view, I mirrored the bend.

[d_spigolon]

good result but I didn't understand.

can you separate the phases?

Do you think it is possible to create a custom family that automatically generates the link?

I created a horizontal run, and then changed the elevation of the run, and created another horizontal run so you have this:

Just delete the bottom elbow and section if you don't need it.

Then I drug the vertical riser past the elbow:

You can do this in a 3D view, or in a section view.  

Then go back to the plan view and create a section.  And mirror the elbow.

Its more of a workaround, but you could trim the vert & horiz. sections and "group" them so they stay together.

You might even be able to lock them to the try so they move with the tray, but they are more workarounds that a working family.

That's the same as I did but without mirroring the bend.

There is this old post: https://forums.autodesk.com/t5/revit-mep-forum/vertical-tee-cable-tray-fitting/td-p/6742801

I must say though that I can't see any manufacturers who supply that fitting "number 17" - where did you get that screenshot @d_spigolon ?

[d_spigolon]

yes of course, for example legrand us

I don't think that's the same fitting as your "item 17"? I think it is meant to be used like this rather than the orientation that you want:

Legrand and Vantrunk have their own BIM content libraries - is their tee family not included in that?

Anyway that link I posted talks about how to create a suitable family.

There are also videos on Youtube which claim to show how to create a suitable family.

I found this on bimobject:

As I said earlier though you might need to create your own family if you can't find a suitable pre-made one.

Hello,

You can create a family for that purpose, but it will not be created automatically.

I suggest you use the multiport part type for this kind of fitting.
