I am wondering if any of you Bright Geniuses out there have any experience with round and rectangular duct (HVAC) in solidworks. I know in REVIT this is a cinch. How would i go about creating sheet metal duct in solidworks that actually looks and unfolds correctly (hems and all)? This seems like a bigger pain than it is worth. I dont have the routing add in so that is out. Any example parts of round and rectagular duct is appreciated.
