I need to show the path of a web for a machine and can't figure out how else to do it but combine a series of 2D sketches with 3D sketches and then sweep the result. Up to this point, I have simply had to create an in-place 2D sketch using the machine's rollers, but now I have to redirect the web as can be seen in the attached part model. In this model, the web redirection is the twist shown by 3DSketch2 connecting web_edge1a with web_edge2a and web_edge1b with web_edge2b.
There doesn't seem to be a way to trim the connected circles in the context of the 3D lines as there is on a plain with lines in that 2D sketch, so I figure that this method of producing a 3D path to be used for a sweep is not supported.
1. Is there a way to trim the circles to the 3D lines?
2. If not, what is the intended method to produce a sweep that would precisely fit the machine's web path?
Thanks in advance for your time.
