Iterative cutting?

[JoshM]

I am manipulating a 2d profile cut from the intersection of a shape on a plane. I have a working method, but it feels hacked, and I was curious if anyone had a better suggestion.

Currently the Cut-Shape is used to cut its inverse--a Bottom-Shape--which I move relative to the top-Shape, taking iterative cuts of the Top-Shape. The drawback is that where the cuts have sharp changes, vertical errors creep in, relative to the step size. It also hacks up any horizontal edges cut by the Bottom-Shape.


The 1st image shows a section where the contour is sharp, but has a flat top, so it hacks up the horizontal line, but introduces no errors...

The 2nd image shows a section where an arc cuts an offset plane to spread the edges around the arc. The vertexes of the iterative cuts are visible.

Thanks,
Josh
