Free Online 3DM to OBJ Converter

You can use our 3DM to OBJ conversion tool to quickly and easily convert your 3D model files for free. You may upload up to 20 files at one time, and our batch 3DM to OBJ converter will process each 3D model and present you with a download link for each file once completed.

Select File(s)

Or drag and drop your files here to upload.
A maximum of 20 files can be uploaded at once.

Please note: Your 3DM file, once uploaded to our server, will be deleted 15 minutes after upload, so please download your converted 3DM file before this time.

Our 3D model 3DM to OBJ tool will load your 3DM file and, where supported, attempt to extract all the relevant 3D features, such as geometry, textures, and animations. To access the 3D conversion configuration options, click the button when you have selected your files. The current options support the ability to voxelize your 3D model and more.

Frequently Asked Questions

How can I convert my 3DM file to OBJ?

First, click the "Upload..." button and select your 3DM file to upload. Your 3DM file will be uploaded to our servers. When the 3DM to OBJ conversion has completed, you can download your OBJ file right away.

How long does it take to convert my 3DM to OBJ?

We aim to process all 3DM to OBJ conversions as quickly as possible; this usually takes around 5 seconds; however, this can be longer for certain files, so please be patient.

How accurate is the 3DM to OBJ conversion?

We aim to provide the best conversion experience. Our tools are under constant review and development, with new features being added every week.

How does converting 3DM to OBJ work?

In order to successfully convert an 3DM formatted file to the OBJ format, our converter tools will perform several initial checks to ensure the file provided is indeed an 3DM file. There are many files out there where the file type extension does not match the data contained within the file. Along with these file type checks, our tools will do additional checks to ensure the file is correctly formatted to match the provided file type. There are many tools out there that do not always create 3DM files to the exact specification.

Take your 3DM file

An 3DM file is a binary data file containing 3D data that makes up the 3D model, including vertices, faces, texture coordinates, and more. To guarantee efficient conversions, our tool will check all data that is contained within the 3DM file and remove any information that is duplicated. This not only ensures the conversion completes more quickly, but also the generated OBJ file size is smaller.

Convert the data from 3DM to OBJ

Now that the data from the 3DM file has been processed, our tool can apply any conversion specified options, such as enabling Voxel mode, and with these applied, prepare the data to be converted to the final OBJ file format. Part of this process ensures checking the capabilities of the OBJ format and removing any data that cannot be represented.

Save to the OBJ format

At this point, the 3DM to OBJ conversion tool will have the 3D model in a state that is ready to be transferred to the OBJ format. Our tool creates the OBJ file, ensuring all the model data is present and is formatted to match the OBJ file specification to ensure the file opens in compatible OBJ file editors.

File format information for 3DM and OBJ

Extension	3DM
Full Name	Rhinoceros 3D
Type	3D Model
Mime Type	x-world/x-3dmf
Format	Binary

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.

Extension	OBJ
Full Name	Wavefront
Type	3D Model
Mime Type	text/plain
Format	Text
Opens With	MeshLab, CAD Assistant, DAZ Studio

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.

OBJ Converter Capabilities

Our 3D conversion tool does not support color or material information in OBJ files, so your file will not contain any color information.

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 it is present in your 3DM file; your final 3D model will contain only geometry data.
