Re: How to flatten 3D surfaces?

I have done this using only SW. You have to use good old descriptive
geometry in a drawing. The object is to divide the surface into
triangles and project them onto a flat surface. It is a time consuming
process but it works. I used the biggest triangles I could and had the
resulting pattern laser cut. The welder did notice the triangulations
on the edges but they were well within the tolerance we needed. This
works best if the surface is not too distorted or stretched.
