3DM Export for Alibre Design is an Rhinoceros 3DM file export add-on for Alibre Design®. This add-on gives Alibre Design the ability to export 3D solid and surface data from a Alibre Design part and assembly document to polygon meshes in a Rhinoceros 3DM file. 3DM Export for Alibre Design tessellates the solid bodies in a Alibre Design part or assembly document into individual triangular meshes. These meshes are then exported to a Rhinoceros 3DM file as polyface mesh objects. 3DM Export for Alibre Design is very easy to use. It adds new commands to Alibre Design. Once installed, it automatically loads itself into Alibre Design and adds a new submenu called "3DMExport" to the Alibre Design menu containing these new commands. The '3DM Export for Alibre Design' menu consists of the following commands: # Export - Export to a 3DM file # Help - Display the 3DM Export for Alibre Design help file # Register - Register your copy of 3DM Export for Alibre Design # About - Display the 3DM Export for Alibre Design About box The 3DM File Format The 3DM (3D Model) file format is the native file format of Rhinoceros, the NURBS modeling software from Robert McNeel & Associates. The OpenNURBS Initiative was founded by Robert McNeel & Associates in January 2000, with the sole purpose of providing CAD, CAM, CAE and computer graphics software users reliable methods for transferring 3D geometry between applications via the 3DM file format. TerrainCAD, our terrain generation, editing and modeling software, also uses the 3DM file format as its native file format
