Hi Leon. Thank you for contacting us. Whenever you want to work on your drawing back in AutoCAD, you can download the drawing back to your computer. On the web app (www.autocadws.com), simply select a drawing you want, then click on the “Download” button in the toolbar, and select a preferred format, and the Autocad version you own. A screenshot is attached. Best Regards.
