The Design menu > Aluminum Frame Design > Reset All Aluminum Overwrites command resets the overwrites for all frame sections with the Aluminum Frame design procedure to their default values. It is not necessary to make a selection before using the Reset All Aluminum Overwrites command. This command automatically applies to all frame sections with the Aluminum Frame design procedure. The command can be used to reverse changes made using the View/Review Overwrites command.
Resetting your overwrites will reduce the size of your SAP2000 database (*.SDB) file.
