Undo and Redo

Undo and Redo functions in Model Editor mode allow you to step backwards or forwards through one or more movement or rotation operations. Undo and Redo operate on a sequence of direct graphical manipulation operations in the Model Editor.

Notes: Undo/Redo operations can also take place outside of Model Editor Mode. If the Undo operation involves moving into or out of Model Editing mode, then the switch into that mode happens automatically, and the Model Editor button and menu option reflect the change. The selection set and handle appropriate to the editing operation that was being used will also be restored.

Other ‘undoables’ (operations or sequences of operations that can be undone) can be defined as a PML ‘undoable object’ - see the Software Customisation Guide
