(...) I mostly meant that I knew what their windings had to be (because of the way the edges are constructed), but the code isn't aware of it. However, like you say, it's easy enough to find an extreme point and test the winding. Steve (20 years ago, 24-Sep-04, to lugnet.cad.dat.ideas, FTX)

(...) You lost me there. How could you not know which is which if they already go in the opposite direction? Just take a cross product at the topmost point. If it's negative, then it's clockwise and thus a hole. Don (20 years ago, 23-Sep-04, to lugnet.cad.dat.ideas, FTX)

(...) OK. My edges already were counterclockwise. :) Umm, for inside outlines (inlines?) to be clockwise, that's 'clockwise' from a global view, right? If so, then my inlines are already clockwise.
