It seems I have come across a problem that is proving somewhat difficult to solve.
I have an extrusion, think of a simple rectangle with some round holes cut or some round extrusions added to the profile. so it's like a swiss cheese, a hole in the middle, a "half-hole" on one edge, a bump on another etc... I don't know if it's even possible to post pictures, if it is then I'll post a snapshot of what I'm talking about.
To my problem
I have created some vba code to go through a selected face, go through all CoEdges and do some custom stuff. The problem arises with arcs. I have x,y,z, start x,y,z, end x,y,z, radius, everything but the direction of the arc is giving me gray hairs.
When I go through all edges of the face each next edge is counter-clockwise from the previous one.
Now my understanding of edge and curve "sense" is it tells you if the edge has been drawn clockwise or counter-clockwise. Which is fine. Exactly what I need in order to figure out whether the arc I'm currently dealing with is an "insie" or an "outside" (i.e. a cut in the side of my profile or a bump along it's edge)
But it's not so simple as I get funny results with one of the arcs. two arcs are fine but the third is allways "wrong way round".
Can someone enlighten me with the use of "sense"?
Thanks!
