Toolbar Button:
Clicking the Display menu > Show Undeformed Shape command or its associated toolbar button does the following:
If the model is being created, this command clears the display of any assignments shown on the model. It functions essentially the same as the Assign menu > Clear Display of Assigns command in this case.
If output results are plotted on-screen on the model, it clears the display of the results and returns the view to an undeformed shape view.
This command affects only the active window.
Note: Undeformed displays also can be accessed by expanding the Undeformed Shape item under Named Displays on the Display tab in the Model Explorer window.
