Hi all. I need create points and get numbering at the intersection positions of line, polyline; and vertex polyline.
Can you help me create lisp?
If you can help me export the number information to excel (include number, x coordinate, y coordinate), that would be great.

Using lisp draw a snake ie a pline crossing verticals near end, then can get closest point to and number. Is this ok method ? If you want just do it then sorry no code.

Hi, @hosneyalaa! 😀

 

Could you help me with your code? I'm trying to run it on AutoCAD 2024, but it seems to not be working as it should be. It won't let me select the polyline in the first prompt and doesn't recognize it:

Thanks in advance!!

Can you attached example drawing 

I tested with just a simple polyline. Can you test if it still working? I'm on AutoCAD 2024..
