Hi James,

So, for a rough outline of an algorithm,
1. Get desired face.
2. Pick desired point on or near the face.
3. Use face drop method to get uv of nearest face point.
(This point may be different, so how to get actual point2 ?)
4. Use face normal method on uv to get normal vector.
(Invert normal option?)
5. How is normal vector and point 2 associated with frame/ rotation info?

For the planar face, the Centroid node provides the point (=point 2).

A modification of Centroid node would take a very few lines of code(?)
(darn spell checker keeps changing my typing :-))
