How to Create a Topography in Rhino from SketchUp - UPDATED!
This is a quick tutorial that shows how to create a topography taken from sketchUp and turn it into a 3D Printable, CNC Mill, or a Contour Model. The programs that I used were SketchUp 2017 and Rhino 5.0. To make the surface contain less triangles when finished - export the surface from SketchUp with more polygons.
