Coping intersecting sheet metal profiles while still be able to generate flat pattern.
I am looking for some work flow to be able to create "coped" custom sheet metal corners( intersections) .
What kind of work flow can I take to develop these profiles with custom copes to generate flat patterns for my plasma to cut.
in this case the material is 1/8 aluminum.
the green and yellow profile in the example would be cut to fit the red and blue profile.
there would be a couple small bit to take off on the red and blue profile too.
ultimately I would want to end up with 4 custom profiles that I could Nest , plasma cut, bend and weld out with a minimum of gaps.
A plasma cutter can only cut straight through the material ( perpendicular ) so the flat pattern would have to reflect that.
Any suggestion how to achieve this?
I would also be valuable if I could go back in my history and change the original opening size and all those changes would carry through the history smoothly.
