    Electrical - Hangers

    Working on my second BIM project and this general contractor is requiring us to show all our hangers on our conduit racks.  What is the best way to show hangers?

     

    Sorry for the question but I don't see any hangers in my available tool list.

     

    Thanks in advance.

    I take it your an electrical contractor sub to the general. The general probably wants the hangers to coordinate with the other trades in MEP. There are some hanger options in MEP and if you search this site you can find them, but I have found the easiest means is to make a block with threaded rod as a solid and a strut block. B-line has some great strut and assembly drawings to use as a profile to build a strut but Kindorf or Unistrut do also.

    Here is a drawing that has some trapeze hanger styles that I created in it.  You will need to use the hangeradd command before you go to the style manager in order to see them.  In addition, in the default MEP template, hangers are turned off in the display configurations.  You will need to turn them on in order to see them.  I believe the following hangers are in the drawing:

     

    1.625 x 1.0 Unistrut with .375 Rod

    1.625 x 1.0 Unistrut with .500 Rod

    1.625 x 1.0 Unistrut with .625 Rod

    1.625 x 1.375 Unistrut with .375 Rod

    1.625 x 1.375 Unistrut with .500 Rod

    1.625 x 1.375 Unistrut with .625 Rod

    1.625 x 1.625 Unistrut with .375 Rod

    1.625 x 1.625 Unistrut with .500 Rod

    1.625 x 1.625 Unistrut with .625 Rod

     

    There is also 2.0 x 2.0 Angle Iron and 3.0 x 3.0 Angle Iron and Rod Sizes from .375 to 1.0 that you can use to make other combinations.  You will just need to go into the style manager->multi purpose objects->hangers and create new combinations.

    I love this! Is it possible to anchor multiple conduits to each hanger? What if they were on strut where that was cut in standard cut lengths (1/2 stick, 1/4, full stick with 3 rods)? I appoligize if this sounds greedy. Thank you for the file. I've just always thought that a rack based approach to conduits/pipe was the way it should be. Does anyone have a script to grab a bunch of different size conduits that are on a rack and set all their top or bottom elevations the same?

    Yes, more conduits can be anchored to the hanger.  It might be better to anchor them to the original conduit though.  To do this you would use the AecObjectAnchorAttach command and select the objects to anchor and then select the object to anchor to.  Objects can only anchor to one other object but an object can have unlimited amount of objects anchoring to it.

     

    As far as the 1/2 stick, 1/4 stick, you will just have to set the length when you insert the hanger.  Unfortunately you cannot automatically add a third rod.  You can though create the third rod in the correct place by using the beamadd command and choosing the correct rod size as your style.  You could then anchor the rod to the hanger and it will now move with the hanger.  Its not automatic but it does work.
