Hello PyMOLers,
I also think it is important to know which vertices are connected to=20
each other in order to form the proper faces. I'm looking into the=20
Blender API a bit more and it looks like it needs the vertex x,y,z=20
coordinates and the "face data" in order to connect the vertices in a=20
meaningful way. These are the two entries I think are important.

Vert(x=3D0,  y=3D0,  z=3D0)
  Get a new vertex object.
  Parameters:
x -  The x coordinate of the vertex.
  =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0  (type=3Dfloat)
y -  The y coordinate of the vertex.
  =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0  (type=3Dfloat)
z -  The z coordinate of the vertex.
  =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0  (type=3Dfloat)
Returns:
  A new NMVert object.
  =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0  (type=3DNMVert)




Face(vertexList=3DNone)
  Get a new face object.
  Parameters:
vertexList -  A list of up to 4 NMVerts (mesh vertex objects).
  =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0  (type=3Dlist)
Returns:
  A new NMFace object.
  =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0  (type=3DNMFace)



I think it would be sufficient to have a txt file that looks like this=20=

with the vertex coord followed by a list of the vertices that make up=20
relevent faces.
