Rhino 6 for Mac: How to model a coffee mug

Introduction: set up units and grid.

Draw a box: absoulte mode and relative mode.

Viewport settings: STRG+TAB to toggle between viewportsshade/wireframe mode

Select object hierarchy with STRG+SHIFT: surface, edges, vertice points

Gumball handles: colors RGB = XYZ

move surfaces: arrows of the gumball Extrude surfaces: points of the gumball

Scale surfaces: square handles hold SHIFT for uniform scaling.

Move and snap surfaces: set snappy dragging (right mouse menue gumball) and use objectsnap

Viewport: ghost and help menue

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

Extrude lines to surface to close open wholes in object handle.

Open polysurface and closed polysurface: use “Join” to create a closed polysurface for 3d printing. Autosave your files!

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.
CMD “ToNurbs”: convert back to Nurbs-model.

Practice until you can build the coffee mug in less than 5 minutes.
You are the champion if you make it in less than 3 minutes!
