Hi, The planar function in grasshopper is working differently as the planar function in Rhino, see example in Rhino:
http://groups.google.com/group/grasshopper3d/web/Bug%20with%20function%20Planar.3dm?hl=en How do I get the Rhino result? (In the end I want to get the area between the curve above and below the X-axis) Who can help? Bas
