This error is getting me! Two times in one week on two separate projects in gh. It happens when i try to extrude planar surfaces with some nice non- freudian holes in them. The nice part is that if i bake the surface and then _extrudeSrf manually in Rhino it works purrferct. only not that parametric :) Here's a screenshot: http://groups.google.com/group/grasshopper3d/web/extrudeNotWorking.jpg
Any suggestions?
