A 3DM file is a widely used file format in the field of computer-aided design (CAD) and 3D modeling. It is primarily associated with Rhinoceros, a popular software used for creating complex 3D models and designs. The 3DM format serves as a container for storing various elements of a 3D model, including geometry, textures, lighting, and other related data. This versatile file format is known for its ability to represent both simple and intricate designs, making it a favored choice among architects, engineers, and designers across various industries.

Within a 3DM file, the geometry information is typically stored in the form of NURBS (Non-Uniform Rational B-Splines) curves and surfaces, which allow for smooth and precise representations of complex shapes. These NURBS-based models offer a high degree of flexibility, enabling users to perform modifications and manipulations with ease. Additionally, 3DM files can include metadata such as layer information, object properties, and assembly structures, making them well-suited for organizing and managing large-scale projects.

One of the major advantages of the 3DM format is its compatibility with a wide range of 3D modeling software. While it is primarily associated with Rhinoceros, many other CAD applications and 3D design tools support importing and exporting 3DM files. This facilitates seamless collaboration between designers and various stakeholders, allowing them to work on the same project using different software. The widespread use of 3DM files in the design industry underscores their significance as a reliable and efficient means of exchanging intricate 3D models.

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.
