Create the handle of the coffee mug with extrude, move…

CMD “Mesh”: create Mesh out of your closed polysurface
CMD “ToSubD” (SubDFromMesh): create openSub object Be aware that the topology of the mesh defines the result of your Opensub.

CMD “PointsOn”: work with control points to shape your OpenSub object.
