(apologies if this mail arrives more than once - didn't get through before because I sent from wrong address) Not sure about this, but how about adding up the total for the angles from one point to the next, for each point? 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]).
