3DM file format information

Full NameRhinoceros 3D
Type3D Model
Mime Typex-world/x-3dmf

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.

Repairing a 3DM File

3DM 3D Model File Header Data

As is common amongst 3D model file formats, 3DM file formats may contain data within their header to help identify the type of file should the filename extension prove to be inaccurate or missing. With the header data from the 3DM 3D model file, we are able to determine core information such as object count, vertex count, faces, textures, and other information, which can then be used to check the validity of the file.

Vertices, Faces and Geometry

This data forms the core element of any 3DM model and, if damaged, cannot be easily recovered. Our 3DM repair tool will try its best to repair and reconstruct any 3D model file it detects to be missing geometric data.

Frequently Asked Questions

Will the quality (vertices or faces) be affected?

Our 3DM repair tool will not intentionally reduce the number of vertices or faces in your 3D model.

Is it free to use the 3DM file repair tool?

Yes! Our 3DM repair tool is 100% free to use.

Are there any usage limits when repairing my 3DM file?

No, you can repair as many files as you wish. We do not have any limits when using our 3DM repair tool.

How long does it take to repair my 3DM?

We aim to process 3DM repairs as quickly as possible; this usually takes around 5 seconds; however, this may be longer depending on the file size and data needed to be repaired.

What does the 3DM repair process involve?

Once your 3DM has been selected, it will undergo some initial checks to verify that the file has some basic information. If the initial checks pass, we then upload the file to our servers for more detailed analysis.

Is it safe to repair my 3DM on

Yes, of course it is! Your 3DM, once repaired, is deleted 15 minutes after upload, and any download link will expire after this time.

Can I repair my 3DM on Windows, Linux, Android, iOS or Mac OS?

Yes! Our 3DM repair tool will run on any system with a modern web browser.
