The MEdgeSeq object

delete(edges)

• any faces which uses the specified edge(s)
• any "orphan" vertices (belonging only to specified edge(s))

Parameters:

edges - can be

• a single MEdge belonging to the mesh
• a single integer, specifying an index into the mesh's edge list
• a sequence (list or tuple) containing two or more of either of the above.

           (type=multiple ints or MEdges)

extend(vertseq)

Add one or more edges to the mesh. Edges which already exist in the mesh are ignored. If three or four verts are specified in any tuple, an edge is also created between the first and last vertices (this is useful when adding faces).

 import Blender
 from Blender import Mesh

 me = Mesh.Get("Plane")          # get the mesh data called "Plane"
 v = me.verts                    # get vertices
 if len(v) >= 6:                 # if there are enough vertices...
   me.edges.extend(v[0],v[1])    #   add a single edge
   l=[(v[1],v[2],v[3]),(v[0],v[2],v[4],v[5])]
   me.edges.extend(l)            #   add multiple edges

Parameters:

vertseq - either two to four MVerts, or sequence (list or tuple) of tuples each containing two to four MVerts.
           (type=tuple(s) of MVerts)

selected()

Returns:

a list of the indices for all edges selected in edit mode.
           (type=list of ints)
