Convert DXF to 3DM

DXF, or Drawing Exchange Format, is a widely-used CAD (Computer-Aided Design) file format developed by Autodesk in 1982. Its primary use is to facilitate data interoperability between various CAD software applications. DXF files represent 2D and 3D designs and contain information such as geometry, layout, and text annotations. Initially created to allow AutoCAD files to be compatible with other programs, DXF has become a standard format for sharing and archiving technical drawings in industries like engineering, architecture, and manufacturing, ensuring seamless communication and collaboration across different CAD platforms.

The 3DM file extension, standing for "3D Model", is associated with the openNURBS initiative, which facilitates the exchange of 3D geometry across CAD, CAM, CAE, and computer graphics software. Developed by Robert McNeel & Associates, it serves as the native format for Rhinoceros (Rhino) software. Introduced to address interoperability challenges, 3DM files store precise 3D models using NURBS (Non-Uniform Rational B-Splines) and polygon mesh representations. This format is widely adopted due to its open-source nature, enabling developers to read and write 3DM files without proprietary restrictions, thus promoting seamless data sharing in 3D modeling workflows.
