What is a 3DM file?
A 3DM file is an open-source 3D model format and native file format for Rhinoceros. It contains a 3D model which includes surface, points, and curve information. 3DM files allow CAD, CAM, CAE, and computer graphics software to accurately save and exchange 3D geometry using both NURBS and polygon mesh representations.
The 3DM open-source library is available at www.opennurbs.org/.
