Gringo Posted August 20, 2008 Share Posted August 20, 2008 (setq PT1 (vlax-curve-getPointAtDist BotObj stepLength)) (setq PT2 (vlax-curve-getClosestPointTo UpperObj PT1) ) (setq Xline (vlax-invoke acSp 'AddXLine PT1 PT2)) (setq PT2 (vlax-invoke Xline 'IntersectWith UpperObj 0)) Ok this is part of a code i got to get the intersection point of a line through two lines - BotObj & UpperObj it is sometimes setting the the PT2 as the further intersection point. How do i make sure PT2 is the closest intersection point of 'UpperObj' from PT1?? Quote Link to comment Share on other sites More sharing options...
borgunit Posted August 20, 2008 Share Posted August 20, 2008 I assume you may know of (DISTANCE pt1 pt2) and then compare between two other points? Quote Link to comment Share on other sites More sharing options...
