In short, it's just a format used for storing 3D designs in a "view only" format. EDRW files are useful when sharing a design not only because the file is compacted to a much smaller size than the raw design, making them much easier to share, but also because the original data can't be tampered with because the format is specially made for viewing a design, not editing it. Even more, drawings in an EDRW file can be examined without the recipient needing a full, bulky CAD program installed. EDRWX files are similar to EDRW files but have been created in the XPS format. How to Open an EDRW File SolidWorks eDrawings Viewer is a free CAD tool that can open and animate drawings in the EDRW format. This program can even protect the EDRW file with a password. Select the FREE TOOLS tab on the download page to find the link. eDrawings Viewer supports other eDrawings file formats, too, like EASM, EASMX, EPRT, EPRTX, and EDRWX. If you find that an application on your PC tries to open the EDRW file but it's not the program you want to use the file with, or it doesn't actually open at all, follow this guide to learn how to fix that in Windows. How to Convert an EDRW File If you download the eDrawings Viewer program from the SolidWorks link above, you can save the EDRW file to BMP, TIF, JPG, PNG, GIF, and HTM. The same program can convert the EDRW file to an EXE file (or even a ZIP with the EXE automatically saved inside) so it can be opened on a computer that doesn't have the eDrawings software installed. You can convert EDRW to PDF with a PDF printer tool. We're not aware of any file converters that can convert EDRW to DWG or DXF, which are two other CAD file formats. However, even with a conversion tool that supports getting the EDRW file into one of those formats, all it would let you do is view the 3D image, not edit it, since it's really just a viewing format. Still Can't Open the File? If you still can't open your file, double-check that you're not misreading the file extension. It's easy to confuse other formats that share similar letters, like DRW (DESIGNER Drawing) and WER (Windows Error Report), with the EDRW eDrawings format.
