Clicking the Display menu >
Show Undeformed Shape command, the Show Undeformed
Shape button, , or the F4 function key does the
following:
If a model is being created, it clears the display of any assignments that are showing on the model. It essentially functions the same as the Assign menu > Clear Display of Assigns command in such cases.
If the on-screen display shows any type of results plotted on a model (e.g., a Deformed Shape), it clears the display of the results and returns the view to an undeformed shape view.
Note that this command only affects the active window.
