Let me re-phrase. Rhino has drawing tools, but everyone I know exports their model to autocad for detailing. Even the Rhino webite says very little about 2D plans, most of the images are of 3D models. However Rhino 5 does have some enhancements in this area, but still the users I know prefer to export to another program for detailing. There must be a good reason for that, or perhaps I just dont know enough Rhino users.
