Hello,

I am looking into using SolidWorks for HVAC design, in terms ofbeing able to detect interference and possibly FloWorks Simulation.

I have imported plan and side views of a generic building design asnew sketches in a part. I have also started to create some ductwork using sweeps and lofts. As you can see from the attachedpicture the sketches show up "in front" of the 3D duct work, Iwould like to have the sketches "behind" the 3D duct work.

Or if anyone has a more efficient way, or a typical way they canuse SolidWorks for duct work, HVAC, plumbing or drainage, ingeneral, please let me know.

Thanks in advance
