Save Copies of Rendered Images
You can save copies of images that are part of a drawing’s render history.
With the Save Copy option, located in the Render Window, you can save a rendered image to a new location even though an output path may already be set. This is useful if you want to re-render a history entry and compare the new image with the previous.
