I am trying to do code group design for my model but I can't assign the sections to the groups. If I go to steel design, then groups and try to select the sections nothing happens, even if I click the section it doesn't show up in the dialog box in selected sections. What could cause this issue?
Another thing is I defined some section for the truss but they don't show up in the user defined database in the group selection dialog. I didn't assign them to any family, should I have done that? And if so, how?
Thanks in advance!
Attached a pic of the dialog box what I'm talking about and a zip file of my model
