Question by Gyntonic · Mar 04, 2018 at 04:39 PM · meshverticesedges

How could I detect the outer edges of a mesh?

I would like to extract the outer edges of a mesh, so I can create an algorithm of 3d placement detecting them and trying to find other mesh that are compatible with that edges.

I'm trying to do something like this:

Example1

Example2

Which is the best way to do this?

Thank you.
