What are 3DM Files?

  • Files with the file extension 3DM are native 3D files of the 3D modeling software Rhinoceros 3D (usually abbreviated to Rhino or Rhino3D).
  • Rhino works in contrast to polygon-based modeling programs with the very precise NURBS modeling. The exact curves, surfaces and shapes are saved in the program's own 3DM format.
  • With the openNURBS initiative and 3DM, Rhino provides other developers with tools for the accurate transfer of 3D geometry.
  • Rhino is not only used in graphic and multimedia design, but also in product design, 3D printing, rapid prototyping and even CAD/CAM.

Rhino Versions

A public beta version of Rhino was released in 1994, but it took four years until the first official Rhino version 1.0 was released in October 1998. Since then, a new major version has been released every 4 to 5 years. The current version is Rhino 8.0. (02/2024)

Models created with newer releases can be exported to older 3DM versions, with the exception of version 1. However, depending on the version, different features and objects are lost.

Additional Native Rhino File Formats

3DM is the only native Rhino file format. Rhino now supports a wide range of file formats as standard, including STEP, IGES, SolidWorks, X_T, OBJ, WRL.

Additional CAD formats, such as CATIA, Siemens NX, Creo and Inventor, are available via plug-ins for a fee.

How Do I Open Rhino 3DM Files?

Typically, a Rhino3D installation is used for this. It is also possible to open with CAD/CAM software that has a 3DM interface, such as SolidWorks.

There are various Rhino 3DM viewers, including free ones, available offline, online and as apps for Android and iOS.

The 3D-Tool CAD viewer opens 3DM files and offers many measurement and analysis tools in addition to simple operation. 3D-Tool can be tested free of charge for 14 days.

How Do I Convert Rhino 3DM Models?

If you do not have CAD software with a 3DM interface, the design must be exported from Rhino to a common 3D exchange format, such as STEP or IGES.

Converting Rhino 3DM to STEP is also possible with a 3D converter or CAD converter.

3D-Tool Premium includes the 3D-NativeCAD Converter. In addition to native Rhino models, this converts models from many common CAD systems into the 3D exchange formats STEP, IGES, SAT and Parasolid X_T supported by many CAD/CAM programs.

Test the Rhino Viewer and Rhino Converter

3D-Tool is a CAD viewer with many native CAD interfaces, including Inventor, and professional measuring functions, demolding analysis and wall thickness analysis.

  • Open and publish 3DM for the 3D-Tool Free Viewer or as 3D-PDF
  • Open 3DM and save as STL, 3DS, PLY, WRL, OBJ, or PLY
  • 3DM (Nurbs) convert to STEP, IGES, VDA, SAT and X_T
