Fologram for Rhino comes with a test scene to verify functionality and performance. It contains several NURBS, Mesh and Text objects with matching materials and textures. The test scene is scaled for the HoloLens field of view, and should be easy to place and inspect for a first time user of the HoloLens. You can experiment with changing the scale of the test scene (for an enormous Stanford Bunny) using the Scale parameter in the Fologram for Rhino plugin.
Loading the test scene will close whatever model is currently open in the Rhino application, so remember to save your work!
To open the downloaded model, go to File -> Open.
