Hi Schbeurd, long time since you've been over here!

re: non-planar faces - I'm a little bit worried about just trying to cook up some kind of average direction for non-planar faces. There may be situations where it causes unexpected results.

Here's an example:



I think it is probably expected in this case for extrude to go directly upwards as shown. But if I tried to take a general averaged normal direction for non-planar surfaces, that would change the default direction for this case to kind of shoot off at some semi-random slanted direction...

Hi Michael. I would most often perceive the average direction to be perp to the surface border (including trim boundaries). In program "R" i would find it by doing something like - dup edges, extract points, fit plane through points, select plane and then cplane to object, then extrude vertical to Cplane. Of course would be nice to do this automatically. The wavy face usually makes no difference to my perceived extrusion path.
