algorithmic modeling for Rhino
You need to supply a list of the vertices that make up a face.
I would suggest you decompose a mesh and see what the output looks like.
Have a look at the image below. In your example on the left the Face that you have defined is {0;1;3;2} and using the Point List component you can see where these points reside. So the resulting face is correct.
On the right is an example with 4 faces defined. Note that I haven't needed to supply the T for triangle like the Q for Quad.
