[Attaching a custom object to truss]

I just migrated to 2022.  Thanks for your help.  I appreciate both options! 

[Attaching a custom object to truss]

I'm a newbie to VW and i've searched the forum unsuccessfully but I'm working on a show and need to add power distribution boxes to the downstage truss for weight calculations.  I tried to create a custom object by using the rectangle tool, create object from shape.  I then input the specific HWD demensions and weight in the object info pallet.  I'm having two problems:

 

1.  The box is still only 2D in the drawing, so clearly just adding HWD measurements do not create a 3D symbol.  

2.  I'm unable to attach the object to the truss.  

 

I'm sure all of this is covered in the VW University videos and on this forum but I could not quickly find it and am on a deadline.  I very much appreciate any help that I might receive here.  

[QSC KLA Series Symbols missing?]

Came to ask the same question.  I see the folder in the resource manager but it remains empty.  I don't even see the flyframe anymore.  We use the KLAs a lot and it would be awesome to have them in the library.
