Hey Ben That is creative thinking...I have no clue if it will work, I'll do a test in a minute but I like the mental process! Never thought about using angles, it won't be 360degs though if it's a polygonal shape but still it absolutely makes sense.. Heh...typical lack of basic math logic...some people blame it on good looking math teachers...in my case she was an ugly old bat, definitely not inspiring math classes (I preferred physics for some reason!?) :)

If it's clockwise the total should add up to 360, if anticlockwise the total should be -360... possibly? or the other way around? (haven't tested, and it's monday morning so I may be thinking along the wrong lines completely!) - Ben _________________ [EMAIL PROTECTED] www.robotduck.com [To remove yourself from this list, or to change to digest mode, go to http://www.penworks.com/lingo-l.cgi To post messages to the list, email [EMAIL PROTECTED] (Problems, email [EMAIL PROTECTED]).
