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...
