Just beginning to integrate Rhino into my CAD/CAM/3D design process and generating custom stair parts for 3 & 5 axis machining. Recently completed some tests with a current stair project and machined the wreath rails on a 5 axis CNC. All rail blocks were created in Rhino, tooled and posted via AlphaCAM.
