As another voice crying in the darkness that is this software, I just want to say that I share your frustration. I am not very impressed with the plumbing module, nor are the other people I work with here. I have gone to using the piping module for domestic plumbing drafting. At least there I can simply change the elevation to get a rise. However, I may need to change the flow direction to get a rise instead of a drop. This also gets my building piping and plumbing look consistent. Another person I work with has taken the approach of drawing a few lines to get the layers set up then explodes them until they are just lines. That way he can add rises and drops and break the crossing pipes without getting the ticks at the end of the pipes. I also considered going back to a machine with Softdesk 8 and copying the LISP routines for drawing plumbing. Again, I question why some of the things that worked well in S8 are completely gone. Just my two cents of venting.
