Hopefully this will be an easy question. I'm working on a 3D drawing that has tubing intersections in various places. For the most part I draw the tubes around centerlines and dimensional laid out per specs, but the result of a lot of intersections of these lines is short tubing pieces that extend just beyond the tubes they intersect. Is there a way to trim this excess tubing off of the picture? I've looked at the TRIM command, but it only seems to work in 2D (unless I'm missing something). Suggestion are appreciated, thanks.
