##Using the plugin After copying this file, start Sketchup and you should now have an extra menu options (Export to DXF or STL) in the Sketchup Tools and File-export menu.
There are five export options:
STL triangles. Use this for Makerbot or Reprap style 3D printers
DXF polyface mesh. This will give the most faithful reproduction of your original Sketchup model.
DXF polylines: exports the outlines of each face as a polyline, sometimes useful for CAM toolpaths.
DXF triangular mesh: breaks all the faces up into triangles
DXF lines. This option exports the edges in your model as lines.
