How to cope multiple steel tube joints?
I've created an engine mounting in Onshape that uses many, mainly 25 x 1 mm steel tubes (it's really a recreation of an old aircraft engine cradle from the early 30's). Anyhow I'm stumped on how to cope the ends of my tubes so they can be cut and welded. My model is at........
I got excited about the beams feature but it can't seem to deal with projected curves. At the moment I have only progressed a very small way, and that was by:
1) creating PART 1 by extruding a tube profile sketch - it's called "Extrude 2 - TUBE B"
(...2) creating PART 2 as a MIRROR of Part 1 - it's called "Mirror 2 - STBD TUBE B")
3) creating PART 3 by extruding a similar tube profile sketch. This intersects Part 1 - It's called "Extrude 1 - Port TUBE A"
4) using the sketch profile of PART 1 to extrude a REMOVE into Part 3, thus coping one end of Part 1 - the resultant feature is called "Extrude 1 - Copes the end of TUBE A"
You will see my drama though when you look at my joints of up to 8 intersecting tubes...........What comes first, the chicken or the egg? or the padded room, soothing music and basked weaving classes?
Indeed because my tubes need coping at both ends I think I would go mad. My next thought was to position sketch planes mid way along my tubes, extrude them in outward directions from that plane, and use the technique above to use 'remove extrusions' to cope the ends.But i still don't know if this is a good idea. Maybe I'm missing something obvious here.
Your advice will be much anticipated and much appreciated.
