Does anyone here have experience making 3D models of headers? I'm curious if there is any math that helps in determining the bend angles or any math relating to headers at all. I'm sure there is some simple geometry that I've forgotten. Otherwise it'll be mostly a rather clunky make-small-adjustments-until-it-all-fits procedure with a little logic applied here and there.



I'm a little farther along than this.
