I have a 3D model which i want to 3D print, it has a face and a hair mesh which i initially joined to export a single PLY format mesh to 3D color printing. But then i noticed that the face and the hair (which both can be separated again easily so don't worry about that) have a gap between them, see: More detailed view:
What i want to do is to extend the hair so it joins with the face. Is there a way to do that? Something like making new edges to join vertices of both groups of vertices?
