algorithmic modeling for Rhino
One for David, there is a bug for the construct quad face. The default vertex numbering is set to 0;1;3;2 instead of 0;1;2;3. I had a large mesh model i was constucting that was composed of 2000 individual meshes with one quad face and 4 vertices. It could not construct the mesh as the face constructor was default to 0;1;3;2. See below

You mean a bug, or you just don't like the default values?
The reason it's 0,1,3,2 rather than 0,1,2,3 is that represents the more common case. When you make a mesh quad grid, you tend to number the vertices per row, then switching to the next column:
When you take the simplest case (one quad, four vertices, two rows, two columns) you get this:
The vertex order for this quad is {0,1,3,2} or {0,2,3,1} for a quad pointing the other direction.

In all my mesh building, I always seem to get the points in 4 groups and change the quad face component to {0,1,2,3}. Actually, if I remember correctly, the mesh component has such a quad face as the default face input.
