• Import
  • 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.

•  MeshSplit
  • 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.
    
    

• ReduceMesh
  
  • 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.

• ShowEdges
  • To make edges respectively holes visible, use the ShowEdges command.
    
    

• FillMeshHoles
  • If you have openings in your mesh which you'd like to close, use the FillMeshHole command.
