Convert EDRW to IGS

Understanding EDRW and IGS file formats

EDRW is a proprietary file format used by SOLIDWORKS eDrawings for viewing, sharing, and reviewing 2D and 3D CAD data. EDRW files are typically used for read-only viewing and markup, not for direct editing or modeling.

IGS (or IGES) stands for Initial Graphics Exchange Specification. It is a widely used neutral file format for exchanging 2D and 3D CAD data between different CAD systems. IGS files are ideal for interoperability and long-term archiving of CAD models.

Why convert EDRW to IGS?

Converting an EDRW file to IGS format allows you to share your CAD data with users of different CAD software, as IGS is a universal standard. This is especially useful for manufacturing, collaboration, or archiving purposes.

How to convert EDRW to IGS

Direct conversion from EDRW to IGS is not natively supported, as EDRW is a view-only format. To convert, you typically need access to the original CAD file (such as SLDPRT or SLDASM) or use SOLIDWORKS with the eDrawings add-in. Here’s how you can proceed:

• With SOLIDWORKS: If you have the original part or assembly file, open it in SOLIDWORKS, then go to File → Save As and select IGES (*.igs, *.iges) as the file type.
• With eDrawings Professional: If you only have the EDRW file, you can open it in eDrawings Professional (not the free viewer). Use File → Save As and check if IGES export is available. Note that this feature may require a licensed version and is not always available for all EDRW files.

Recommended software for EDRW to IGS conversion

• SOLIDWORKS – Best for users with access to original CAD files.
• eDrawings Professional – Useful if you only have EDRW files and need to export to IGS (feature availability may vary).
• Online CAD converters – Some online services claim to convert EDRW to IGS, but results may vary and security should be considered.

Important notes

• EDRW files are typically for viewing only; conversion may not be possible without the original CAD data.
• Always check for data loss or geometry issues after conversion.
• For best results, request the original CAD file from the designer if possible.
