Autodesk Viewer lets you download images of your designs with its built-in screenshot feature. Screenshots are supported for both 3d and 2d designs. You can use the toolbar to display and position the model for the screenshot. See Autodesk Viewer Tools to learn how to interact with models using the toolbar.
To take a screenshot:
Click the Screenshot icon. A thumbnail of the screenshot will appear to the right.
Position the model. The thumbnail will reflect your changes.
Once your design is ready, click Download to save it to your computer.
