I am working on a welded steel pipe fitting that adapts to ss tube. So I created a routing part with two connection points. One connection point references the pipe part file and the other connection point references the butt welded stainless tube part file. However, when I start a route with the part, the routing manager only allows me to create a route using one pipe file. As a result, I have put my butt welded tube and pipe in one file. Is there a way to reference two part files for pipe?
