Maya API add/remove vertices/edges from existing mesh

Question

Is there a way to add/remove vertices, edges and faces from existing meshes with Python API? I found a few question around the web about this, but all without answer.

Answer 1

In OpenMaya.MFnMesh there are some methods for this:

• To delete:
  • deleteEdge(edgeId, modifier=None) -> self
  • deleteFace(faceId, modifier=None) -> self
  • deleteVertex(vertexId, modifier=None) -> self
• To add:
  • addPolygon(vertices, mergeVertices=True, pointTolerance=kPointTolerance, loopCounts=None) -> faceId; Which merges vertices within a certain range (pointTolerance).

So it seems like you cannot just create single vertices and then properly connect them with edges and faces, but you have to define a complete polygon.

If there are other solutions I would be happy to know!
