Convert OBJ to EPRT

Understanding OBJ and EPRT file formats

OBJ is a widely used 3D geometry definition file format developed by Wavefront Technologies. It stores 3D model data, including vertices, texture coordinates, normals, and faces, and is supported by most 3D graphics applications.

EPRT is a file format associated with eDrawings, a viewer developed by SolidWorks for sharing and viewing 3D models. EPRT files are compressed, read-only representations of 3D models, optimized for easy sharing and viewing without exposing the original CAD data.

Why convert OBJ to EPRT?

Converting OBJ to EPRT allows you to share 3D models in a secure, lightweight, and easily viewable format. EPRT files are ideal for collaboration, as they can be opened with the free eDrawings Viewer, making them accessible to users without specialized 3D modeling software.

How to convert OBJ to EPRT

Direct conversion from OBJ to EPRT is not natively supported by most 3D modeling tools. The recommended workflow involves importing the OBJ file into a CAD application that supports eDrawings export, such as SolidWorks, and then exporting it as an EPRT file.

Step-by-step conversion using SolidWorks

1. Open SolidWorks.
2. Go to File → Open and select your OBJ file.
3. Once the model is loaded, go to File → Save As.
4. In the Save as type dropdown, select eDrawings (*.eprt).
5. Click Save to export your model as an EPRT file.

Best software for OBJ to EPRT conversion

• SolidWorks (with eDrawings Publisher): The most reliable method for converting OBJ to EPRT.
• eDrawings Professional: Can open supported CAD files and export to EPRT, but may require initial conversion to a SolidWorks-compatible format.

Tips and considerations

• Ensure your OBJ file is properly formatted and free of errors before importing.
• Some geometry or textures may not transfer perfectly; review the model in SolidWorks before exporting.
• If you do not have access to SolidWorks, consider using a trial version or seeking assistance from a service bureau.
