Hi all,

I'm in the process of switching our project from 1.48 to 1.50. There were some warnings in geometry 1.48 that seem to have been resolved. Thank you! On the other hand, there are new warnings in geometry 1.50. IMO, these warnings should be eliminated (for a couple of reasons, one being that they clutter the output window and obscure new/unknown warnings that may be important).

I am compiling with MS VC++ 10 for 32 bit. My polygon type is oriented counter-clockwise and not closed, my point type is based on int.

Regards

Volker
