Compound Angles & 2d Templates

robert_melascaglia

Greetings All

I have a simple question where a compound angle was created to the cross-section of a 2" x 1" rectangle tube.  No big deal, Onshape handles that easily.

However, we can create "perfect geometry" in Onshape then go to the shop and scratch our heads trying to figure out how to fabricate.

Without purchasing a Sliding Compound Miter Saws; I was wondering.  Could Onshape help me to create a 2d pattern of the "compound angle" where
I could print the template, wrap it around the tubing, and cut the four sides with a grinding wheel?

Appreciate your assistance.

Try this sample using sheet metal to get wrap-able flat pattern.

When satisfied with results change break variable to something small to get rid of gap.
Should work on most shapes if you are familiar with OS sheet metal.

Do you have access to a 3D printer? If so I'd print the template as a jig that slides over the tube then scribe around it. Or maybe get fancy with some offsets for a guide Bush and a hand held plasma torch.
O.S.
