How to generate a rapid prototype of your mesh
Generating a rapid prototype of your mesh requires that you export you mesh geometry into a standard CAD file format.
Solid works (a popular CAD package) accepts iges files.
Simply load your mesh into cmgui and then use the
gfx export iges ....
command to export the mesh. Once loaded into a CAD package such as solidworks you will be able to export the mesh to many file formats.
This will allow you to load your mesh into your rapid prototype software and print your 3D mesh.
