    Default How to easy find closed overlapping polylines

    Hello I'm new to this forum, student Civil engineering at Hanze Hogeschool Groningen. I found a LISP file which finds closed overlapping polylines and for me it's very useful to find overlapping yard boundaries. But I’m looking for an extra function.


    My issue:
    By using the current LISP file I only can check on 2 closed polylines (yard boundaries) at once.
    So when there are multiple closed overlapping polylines and you want check in one go where these polylines overlap. I may just need to adjust an extra command prompt in the LISP file (?). Does anyone know what have to be added to the LISP file to make it work on multiple closed polylines by selecting them once.


    I hope someone can help me out and I'm not expert in programming LISP routines[ ATTACH=CONFIG]106631[/ATTACH]
    select autocad.png.

    I haven't looked at modifying the existing method, but, you might like this other one from Lee Mac.
