Convert STL to EASM

Understanding STL and EASM file formats

STL (Stereolithography) is a widely used file format for 3D models, especially in 3D printing and computer-aided design (CAD). It represents the surface geometry of a 3D object without any color, texture, or other attributes. EASM (eDrawings Assembly) is a proprietary file format developed by Dassault Systèmes for use with the eDrawings Viewer. EASM files are used to share 3D models and assemblies in a lightweight, view-only format, often for collaboration and review.

How to convert STL to EASM

Direct conversion from STL to EASM is not natively supported by most software, as STL is a mesh format and EASM is a proprietary viewing format. The typical workflow involves importing the STL file into a CAD program that supports both STL 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 STL file.
3. Once the STL is imported, you may need to convert the mesh to a solid body for better compatibility.
4. After preparing the model, go to File → Save As.
5. In the Save as type dropdown, select eDrawings (*.easm).
6. Click Save to export your file as an EASM.

Recommended software for STL to EASM conversion

• SolidWorks (with eDrawings Publisher): The most reliable and accurate method for converting STL to EASM.
• eDrawings Professional: Can open SolidWorks files and export to EASM, but requires the model to be in a compatible format first.

Tips and considerations

• STL files are mesh-based and may lose parametric data when imported into CAD software.
• Ensure your STL is properly scaled and oriented before exporting to EASM.
• EASM files are view-only and cannot be edited, making them ideal for sharing and review.
