IntersectWith Method

Christian Krätschmer

Can anyone help me to get a working "intersectWith" Method in C#

I create a Line and a Polyline and now i want the intersection points of these two elements.

I don't know which values i have to pass.

I have tried something like this

Polyline _poly=new Polyline(); Line _line=new Line(); Point3dCollection _pnt=new Point3dCollection();

....

_line.IntersectWith(_poly, Intersect.ExtendThis, _pnt, ????) - isn't there an option for Intersect.ExtendNone?

Hi!

Use something like this (VB.NET) :

Dim points As New Point3dCollection

 - points is empty and will populate if find intersection

             

_line.IntersectWith(_poly, Intersect.OnBothOperands, points, IntPtr.Zero, IntPtr.Zero)

 - if points collection is empty then line and polyline doesn't intersect
