Most MEP Constuction companies would use Unistrut channels to support pipes and ductwork. However, there is no CAD product out there would allow you to create intelligent connections. I would like to Autodesk to have a Unistrut channel catalog (see attached) loaded into Advanced steel. This would include Unistrut catalog connection vault similar to steel beams. For example, when I want to connect two channels together the fittings and bolts etc would appear in the 3D model and Bill of materials.
