Jonathan Handojo Posted January 7, 2021 Share Posted January 7, 2021 You mean the intersection between the red line and all the white lines? Refer to our legend here: http://lee-mac.com/intersectionfunctions.html#intersectionsbetweensets It works fine to me when I tried inspecting: (LM:intersectionsbetweensets (ssget '((62 . 256))) (ssget '((62 . 1)))) 2 Quote Link to comment Share on other sites More sharing options...

Trudy Posted March 18, 2021 Author Share Posted March 18, 2021 (edited) Hello again. Another problem when i use (setq int3 (LM: intersections (vlax-ename-> vla-object nam) (vlax-ename-> vla-object nam2) acextendnone)) But this dont work every time and dont know why. Sometimes work perfect but when i try with large scale dont work at all. I want to get all intersect point for every object (nam2) with another object (nam). Edit: When i want to use "entmake" Line in this function, then dont work good. Edit2: I understand how it work. Now work fine. Thanks for help Edited March 18, 2021 by Trudy Quote Link to comment Share on other sites More sharing options...
