Hi, I have a grading plan from a consultant which is all 3D polyine contours. What I have to do is clip out the grading of the site exterior from the site interior. All that i have is a 2D polyline which represents that boundary. Is there a way to clip out the 3D polyline contours with a 2D object? Is there a simple way to transform that object into something useful?
Edit: I guess the easiest thing would be if I could clip non coplanar 3D poly's. I want my 2D poly boundary to be able
