I am using Inventor Routed Systems 2011 and frequently use the ANSI B88 or ANSI B88M copper tubing styles. I would like this style to use wrought 45 degree and 90 degree elbows along with straight couplings. The system, however, inserts copper bends instead of adding fittings. I had tried to copy a style that included elbows, but none that I see have the remaining features matching the copper braised/soldered style. For example, a threaded steel pipe style uses all the fitting types I would also like to use (in copper), but requires thread length, etc...

Has anyone figured out how to modify or create a copper style that uses fittings in place of tube bends?

Thank you,
John
