Hello,

I need to find the contact boundary / boundaries between two mesh objects.

In the second screenshot below I marked the curve I want to automatically extract, if possible.

Basically, what I need is a concave hull of all points that are very close to both Meshes.

The only idea for an alogorithm I have so far, will generate points on the contact area between the meshes, but not a closed curve of the boundary.

I appreaciate any ideas and tips
