UTILITY SETUP UNDO ON/OFF

          

This command enables the FEMGEN undo facility to be switched on and off.

The undo works by making a copy in memory of the current state of the FEMGEN model prior to executing any command, with the exception of MESHING GENERATE, that will change the model in any way.

Only one previous state of the model is maintained.

By default the undo is switched on when starting a FEMGV session and is a session wide control.

If the undo facility is on, then the command UTILITY UNDO will return to the previous state of the model.

Note that when active the undo facility imposes an overhead in memory requirement and response time. When reading in command files that contain no UTILITY UNDO commands the best performance will be obtained by setting the undo off. However, for normal interactive working it is recommended to have the undo facility on. The current setting of the undo switch is shown with the command UTILITY TABULATE GEOMETRY STATUS.

Examples:

1.

UTILITY SETUP UNDO ON

This command switches on the undo facility.

2.

UTILITY SETUP UNDO OFF

This command switches off the undo facility.
