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))))

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
