Polyline and Line intersecting

[Jozi68]

I have a polyline in a variable called myPL. I have a line in a variable called myLine. How do I get all points where they intersect?

I'm woking in 2D.

try this: (vlax-invoke myPL 'intersectwith myLine acExtendNone)

As an extension of Ron's excellent post:

 

(vlax-list->3D-point
 (vlax-invoke myPL 'IntersectWith myLine acExtendNone))

(defun vlax-list->3D-point (lst)
 (if lst
   (cons (list (car lst) (cadr lst) (caddr lst))
         (vlax-list->3D-point (cdddr lst)))))

Sorry guys, this is all greek to me. I forgot to mention; I'm using Dot net. Can you perhaps translate any of this?

Jozi, I'm afraid there are only a few guys on this forum that know .NET - if you don't get a good response here - try over at theSwamp.org, they have a forum dedicated to .NET programming - you'll feel right at home
