Convert EASM to SAT

Understanding EASM and SAT file formats

EASM (eDrawings Assembly) files are proprietary 3D visualization files created by Dassault Systèmes' eDrawings software. They are primarily used for sharing, viewing, and reviewing 3D CAD models without exposing the original design data. EASM files are highly compressed and optimized for easy distribution and collaboration.

SAT (Standard ACIS Text) files are ASCII-based 3D model files used by the ACIS geometric modeling kernel, which is widely adopted in CAD applications. SAT files store precise 3D geometry and are commonly used for data exchange between different CAD systems.

Why convert EASM to SAT?

Converting an EASM file to SAT format allows you to extract 3D geometry from a view-only eDrawings file and use it in CAD programs that support the ACIS SAT format. This is useful for further editing, analysis, or integration into other design workflows.

How to convert EASM to SAT

Direct conversion from EASM to SAT is not straightforward because EASM files are intended for viewing, not editing or exporting. However, if you have access to the original CAD file (such as a SolidWorks assembly), you can:

1. Open the original CAD file in its native application (e.g., SolidWorks).
2. Go to File → Save As or File → Export.
3. Select SAT (ACIS) as the output format.
4. Save the file.

If you only have the EASM file, you can try the following workaround:

• Open the EASM file in eDrawings Professional (not the free viewer).
• If export options are enabled, use File → Save As and check if SAT or another editable format is available. Usually, export is limited or disabled for EASM files.
• If export is not possible, request the original CAD file from the author for proper conversion.

Best software for EASM to SAT conversion

The most reliable way to convert is to use the original CAD software (such as SolidWorks) that created the EASM file. If you have the source file, open it and export to SAT. eDrawings Professional may offer limited export capabilities, but typically does not support direct SAT export from EASM files.

For professional needs, consider using Autodesk Inventor, SolidWorks, or Autodesk Fusion 360 if you have access to the original model. Online converters do not support EASM to SAT due to the proprietary and view-only nature of EASM files.

Summary

Direct conversion from EASM to SAT is generally not possible due to format limitations. The best approach is to obtain the original CAD file and export it to SAT using professional CAD software.
