- Import your 3D model
- Use the Import command for importing your 3D scan (.stl file) into Rhino.
- Hint: If you can't see anything after importing, check the Zoom extents button in the tool bar.
- Cut your mesh
- You need a surface to cut a mesh. Use the Surface command to do this.
The MeshSplit command divides meshes into parts with another object, in this case your surface.
- Simplify your mesh
- If you haven't scanned an object but downloaded a high res 3d object / mesh, you can simplify this. You'll need this later when working with Grasshopper.
The ReduceMesh command decreases the polygon mesh face count while minimizing geometric and texture distortion.<image before / after>
- ShowEdges
- MatchMeshEdge
The MatchMeshEdge command moves face edges of an open mesh to meet adjacent face edges.
