The 3DM file format is a 3D Computer Aided Design (CAD) format primarily used by the Rhinoceros CAD software. It enables the storage of both simple and complex 3D models within a standard package and has found many uses within the architectural, engineering, and manufacturing arenas.

The format allows the storage of 3D model geometric data, including mesh and texture coordinate data. This 3D data is stored in the NURBS format, allowing complex objects to be represented with high precision.

Although primarily designed for use with the Rhinoceros CAD software, 3DM files enjoy support amongst other CAD software, with many supporting the import and export of data to the format.

3DM Converter Capabilities

Our 3DM 3D Model/Mesh tool does not support any color material data contained within 3DM files so the converted file will not contain any color information.

The OBJ file format is a 3D graphics file format used to define complex 3D models, including geometry, materials, and textures. OBJ files are text files, making them human-readable and easy to modify by hand. The downside to this ease of readability is that the files can become rather large when dealing with large or complex 3D models.

As mentioned, the OBJ format stores not only 3D model geometry but also materials and textures. These materials are usually defined in a separate file with the MTL file extension and specify geometry rendering details such as diffuse and specular color, transparency, and much more.

The OBJ material file can also reference external texture files. These are usually JPEG or PNG files; however, these can be older formats, such as TGA. Where materials are used, the OBJ file will also contain material names preceding the geometry faces they should be applied to. If textures are referenced, the geometry will also contain texture coordinates (UV) for each vertex.

Information for converting from 3DM to OBJ

Your 3DM file will be converted to a OBJ file using our unified 3D model and mesh conversion tool. Our 3DM 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. Our tool will not attempt to transfer any color information if present in your 3DM file, your final 3D model will contain geometry data only.
