Convert EASM to STEP

eDrawings files (EASM, EPRT, EDRW) from SolidWorks are designed for viewing and sharing, not editing or converting CAD files. This means that eDrawings files cannot be converted to anything else in most cases simply because they are used as previews and for printing—not for further editing. They are similar to PDFs, used only for CAD/3D designs.

Still, there are perhaps some ways to approach and potentially achieve an easy-to-step easm to step conversion or similar export.

How to convert eDrawings files to STEP format

Ask the author

• First and foremost, obtaining the source file is the most convenient way to approach this, but it is not always possible. The person who sent you that file might even make the STEP export for you without needing to send the file.

Using eDrawings Professional

• Suppose you have access to eDrawings Professional (the paid version of eDrawings). In that case, you have more functionality than the free version, including the ability to save eDrawings files as STL and other formats suitable for 3D printing. Once you have STL format, it shouldn't be difficult to convert it to STEP format with one of the available stl to stp converters.

Using SolidWorks

• If the eDrawings file was originally created from SolidWorks, the best way to export it to another format is to use SolidWorks. However, you will need the source file for this; in the case of the .easm file, it would be the .sldasm assembly file.
• Open the original SolidWorks file and use SolidWorks' export functions to save it in the desired format, in case of easm to step conversion, this would be STEP/STP.

Conversion Tools and Services

• Some software designed for CAD interoperability and data exchange might be able to handle eDrawings files, but the chances are pretty low. These tools often support various formats and could potentially export eDrawings files to other formats, including STEP.
• Third-party tools and online conversion services claim to convert eDrawings files to other formats. However, the reliability and effectiveness of these tools can vary, and it's important to be cautious with sensitive data when using online services.
