Hi List,

I am looking for point in poly code. Specifically, I would like to pass a
point, and a poly to a routine and return whether the point is inside or
outside the polygon and how far from the polygon the point is. If its in,
then how far inside, if its out, then how far outside.

Can anyone point me in the right direction to locate the pieces of this?

Thanks,
