Hi.

I need help with wirting a lisp that takes polyline vertices and use them to create sectionline using the "SECTIONLINES" command.

I wrote a lisp to select a polyline and get its vertices points in to a list - see attached aa.lsp,

and also attached is a simple drawing with tin surface and a polyline that I want to use to create the sectionline.

Also attached a short video shows what I'm trying to do with lisp.

thanks,
