Convert 3DM to DAE

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.

The DAE file extension stands for Digital Asset Exchange, a format used for exchanging 3D digital assets between various graphics programs. Developed by Sony and now managed by the Khronos Group, DAE files are based on the COLLADA XML schema and are widely supported by software like Autodesk Maya, Blender, and Adobe Photoshop. This format facilitates interoperability among different 3D modeling and animation tools, making it a standard in the industry.
