Hi there! First post!
Based upon some code that I've found (in this group) about looping over
faces and getting their centers, I ran into the following problem.
I've highlighted 2 methods in the polyIter section where I try to store the
center as an MPoint.
center is already an MPoint*, but apparently I'm not allowed to store the
point directly into a list. Anybody who can point out why this is? Because
it's an MPoint reference?
