I extruded a curve then caped it and converted to a poly-surface. now I want to convert to a mesh, how doI about doing that
Select the polysurface and then run the Mesh command: Mesh->From NURBS Object on the menu.
By the way, this isn't really a programming question, so it's not really appropriate for StackOverflow. However, we'd love to have you ask Rhino related questions at http://discourse.mcneel.com/
