Brep to surface - section curve experiments

Dear friends,

I am, again, working on building a surface from breps. We all know that we need surfaces in order to use the full spectrum of Grasshopper, e.g. when mapping and morphing.

It is a hard task and I am looking for strategies that could be adapted to various geometry. Attachedtest.gh (33.4 KB) is a file that I would like to discuss with you. The result is ok but there are many discrepancies when it comes to tolerance. The goal is of course to create an absolutely exact surface version from the original brep.

Maybe you have better ideas than I have.
