I have been mainly a duct designer but have been asked to do a 3D pipe coordination project. I have checkd other posts but they are for someone that already knows what they are doing and just need help with some issues. Tried checking the tutorials section but the latest version on there was 2010. Does anyone know where I can get a decent tutorial on drawing 3D pipe? Mainly having problems with 1/8" slope sanitary and storm....thanks
