<p>Embodiments of the invention provide a visual command history for a software application. A method for generating a visual command history for a software application configured to edit a computer-aided design (CAD) drawing may include receiving a selection of a command to perform, determining an area of the CAD drawing modified by the command. When the command is performed, the method may include capturing at least one image of the area of the drawing modified by the command and storing the images in the visual command history. The visual command history is configured to maintain a record of each command performed by the software application. A user may interact with the visual command history to undo a sequence of commands performed using the software application beginning from the most recent command up to command selected from the visual command history.</p> |
