Convert IGES to EASM

Understanding IGES and EASM file formats

IGES (Initial Graphics Exchange Specification) is a widely used neutral file format for exchanging 2D and 3D CAD data between different CAD systems. It stores information about wireframes, surfaces, and solid models, making it ideal for interoperability in engineering and manufacturing workflows.

EASM (eDrawings Assembly) is a proprietary file format developed by Dassault Systèmes for use with the eDrawings Viewer. EASM files are highly compressed, read-only representations of 3D assemblies, allowing for easy sharing, viewing, and collaboration without exposing the original CAD data.

How to convert IGES to EASM

Direct conversion from IGES to EASM is not natively supported by most CAD software, as EASM is a visualization format. The typical workflow involves importing the IGES file into a CAD program that supports both IGES import and eDrawings export, such as SolidWorks.

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, review and repair any geometry if necessary.
4. Go to File → Save As.
5. In the Save as type dropdown, select eDrawings (*.easm).
6. Click Save to export your assembly as an EASM file.

Recommended software for IGES to EASM conversion

• SolidWorks – Best for seamless IGES import and EASM export.
• eDrawings Professional – Useful for viewing and sharing EASM files after conversion.

Key considerations

• EASM files are read-only and cannot be edited like native CAD files.
• Ensure your IGES file is properly structured to avoid geometry errors during import.
• Batch conversion is possible with SolidWorks Task Scheduler for multiple files.
