I am just learning the software and obviously the services seem to be the heart of the program. I can find no documentation as to how to set them up properly. Where can I find the proper way to set them up. Say I want to setup hangers, insulation, some design lines do not fill from a imported revit design line. I find one setup works and then another wont. Some imported lines have hangers others dont. Some elbows fill in and yet others do not. So any help is greatly appreciated.
