Undo/Redo function
Use these functions to undo and redo one or more sequential events that occur while working with the current file. An event is defined as a function-based operation. There is no difference between creating a single line and using a Transform function to create 100 lines. Each is a single event.
The events you can undo and redo are limited to Mastercam CAD functions, including those that you use to create or edit geometry, drafting entities, and file annotations, and to modify entity attributes. You can also undo/redo solids creation and transform operations.
Use the undo/redo controls at the top of the Solids Manager when editing Model Prep functions.
For some CAD functions, you can undo your modifications while they are live, such as when creating a Line endpoint or using the Trim to Entities function.
Due to the complex and associative nature of creating and modifying toolpaths, you cannot undo or redo toolpath-related functions such as edits made to geometry (including solids) through the Toolpaths Manager. The following CAD functions are not saved as events:
- Editing live entities. However, fixing the entity by exiting the function is saved as an event. If you undo this type of event, you delete the entity.
- Delete/Undelete
- Blank/Unblank
- Hide/Unhide
- Setting system attributes (color, level, point and lines styles)
- Zooming or panning images in the graphics window
When you open a part file or create a new file, Mastercam clears the list of undo/redo events from memory. Saving or merging the current file does not clear this list.
By default, Mastercam can save unlimited undo/redo events, restricted only by the amount of random access memory (RAM) available on your PC. To enhance your PC performance, you can configure Mastercam to store only a specific number of events and allocate a maximum amount of RAM to the undo/redo functions.
