Convert IGES to EPRT

Understanding IGES and EPRT file formats

IGES (Initial Graphics Exchange Specification) is a widely used file format for exchanging 2D and 3D CAD data between different CAD systems. It stores geometric and product definition information in a text-based format, making it ideal for interoperability in engineering and manufacturing workflows.

EPRT is a file format associated with eDrawings, a viewer developed by SolidWorks. EPRT files are highly compressed, read-only representations of 3D models, allowing users to share and view CAD data without exposing the original editable files. EPRT files are commonly used for collaboration, design review, and communication with stakeholders who do not have access to full CAD software.

How to convert IGES to EPRT

Converting an IGES file to EPRT involves importing the IGES file into a compatible CAD application and then exporting or publishing it as an EPRT file. The most reliable way to perform this conversion is by using SolidWorks with the eDrawings Publisher add-in.

Recommended software for IGES to EPRT conversion

• SolidWorks (with eDrawings Publisher): The industry-standard solution for this conversion. SolidWorks natively supports IGES import and, with the eDrawings Publisher add-in, can export models as EPRT files.
• eDrawings Professional: Allows opening IGES files (after conversion in SolidWorks) and saving them as EPRT for sharing and review.

Step-by-step conversion process using SolidWorks

1. Open SolidWorks.
2. Go to File → Open and select your IGES file to import it.
3. Once the model is loaded, go to File → Publish to eDrawings (or File → Save As and choose EPRT as the file type if available).
4. Configure any export options as needed, then save the file. The output will be an EPRT file ready for sharing or review.

Tips and considerations

• Ensure the eDrawings Publisher add-in is enabled in SolidWorks for EPRT export functionality.
• Check the imported geometry for accuracy before exporting, as IGES files may sometimes lose feature data during import.
• If you do not have access to SolidWorks, request the conversion from a colleague or use a professional CAD conversion service.
