Tharwat Posted April 5, 2021 Share Posted April 5, 2021 This should be the missing part you need to finish the goal of your program and I am sure that you do the rest part for lines. ;; where variables: ;; ;; obj = Green Polyline. ;; ;; lst = list of intersected points. ;; ;; srt = sorted points to use to create lines in order. ;; (foreach pt lst (setq pts (cons (vlax-curve-getdistatpoint obj (vlax-curve-getclosestpointto obj pt)) pts)) ) (setq srt (vl-sort pts '(lambda (j k) (< j k)))) 1 Quote Link to comment Share on other sites More sharing options...
