Convert 3DM to 3DX

Understanding 3dm and 3dx file formats

3DM is the native file format for Rhinoceros 3D (Rhino), a popular 3D modeling software. It is based on the openNURBS initiative and is widely used for storing NURBS geometry, meshes, and related 3D data. 3DX, on the other hand, is less common and is typically associated with Dassault Systèmes' 3DEXPERIENCE platform. It is used for collaborative 3D design, simulation, and data management, often in industrial and engineering contexts.

How to convert 3dm to 3dx

Direct conversion from 3DM to 3DX is not widely supported due to the proprietary nature of the 3DX format. However, you can use an intermediate format such as STEP (.stp) or IGES (.igs) to transfer geometry between applications that support these formats.

Recommended software for conversion

• Rhinoceros 3D: Export your 3DM file to a neutral format like STEP or IGES using File → Export Selected and choosing the desired format.
• Dassault Systèmes 3DEXPERIENCE: Import the STEP or IGES file and save or export it as a 3DX file within the platform.

For automated or batch conversions, consider using Autodesk Fusion 360 or SolidWorks as intermediaries, as they support a wide range of 3D file formats and can facilitate the transfer between 3DM and 3DX-compatible formats.

Step-by-step conversion process

1. Open your 3DM file in Rhinoceros 3D.
2. Go to File → Export Selected and choose STEP (.stp) or IGES (.igs) as the export format.
3. Open the exported file in 3DEXPERIENCE or compatible Dassault Systèmes software.
4. Import the file and save or export it as a 3DX file.

Tips and considerations

• Check for geometry or data loss during conversion, especially with complex models.
• Maintain backups of your original files before conversion.
• Consult the documentation of your target software for specific import/export capabilities.
