Silhouette on triangle mesh

Bonjour,

Calling for the collective wisdom. Not a Moi question, really :

I have a triangle mesh where I need to find the split lines for making a mold. Would this be a regular model, the Silhouette command would be the right tool.

What software out there in the wild can determine the silhouette of a mesh, bringing the resulting line back into Moi for further mold design? I trust some of you have a bookmark that can help me out.

Thanks a ton,
Ditto
