Splitting a Mesh into Inner and Outer Surfaces –Cleaner Edges?

[DanielPiker]

It looks like your input mesh was at some point a structured quad mesh which has been triangulated. So you could still walk along mesh edges by angle using something like the script from Junichiro Horikawa that is included in this definition:

How to find "locally" geodesic paths in surfaces?

@PeterFotiadis - Learning a bunch from your posts, and don’t intend to undermine them! But just to follow up on the previous question, if tracing the actual mesh edges is desired, a mesh walking algorithm may be sufficient?
