Convert EDRW to IGES

Understanding EDRW and IGES file formats

EDRW is a proprietary file format used by SolidWorks eDrawings for viewing, sharing, and reviewing 2D and 3D CAD drawings. EDRW files are typically read-only and are designed for collaboration without exposing the original design data.

IGES (Initial Graphics Exchange Specification) is a widely used neutral file format for exchanging 2D and 3D CAD data between different CAD systems. IGES files have the .igs or .iges extension and are ideal for interoperability in engineering and manufacturing workflows.

Why convert EDRW to IGES?

Converting EDRW to IGES allows you to transfer CAD data from SolidWorks eDrawings to other CAD platforms that support IGES, enabling further editing, manufacturing, or analysis.

How to convert EDRW to IGES

Direct conversion from EDRW to IGES is not natively supported because EDRW files are intended for viewing only. To convert, you need access to the original SolidWorks file (SLDPRT or SLDASM), or you must request the editable file from the author. Once you have the original file, follow these steps:

1. Open the original SolidWorks file in SolidWorks.
2. Go to File → Save As.
3. In the Save as type dropdown, select IGES (*.igs, *.iges).
4. Click Options to adjust export settings if needed.
5. Click Save to export your file as IGES.

Best software for EDRW to IGES conversion

The most reliable method is using SolidWorks itself, as it provides full access to the model data. If you only have the EDRW file, you cannot convert it directly to IGES due to its read-only nature. If you need to view or share the file, eDrawings Viewer is suitable, but for conversion, request the original SolidWorks file from the creator.

Summary

To convert EDRW to IGES, you must obtain the original SolidWorks file and use SolidWorks to export it as IGES. Direct conversion from EDRW is not possible due to format limitations.
