This article explains what an EDRW file is, how to open it on your computer or phone, and how to save it as a JPG or other image format for easier viewing and sharing.
Solidwork converts Step file to Solidworks parts
A file with the EDRW file extension is a CAD drawing used with SolidWorks eDrawings. In short, it is a format used for saving 2D designs in a "view only" format.
These files are useful if you want to share a design, not only because the file is compressed to a much smaller size than the raw design, making them much easier to share, but also because the original data cannot be manipulated. This is because the format is specifically designed for viewing a design, not editing it.
Drawings in an EDRW file can be viewed without the recipient having to install a comprehensive CAD program.
