   • A dialog box will appear with the current dimension value.
   • Enter the new value in the dialog box and press Enter.
   • The sketch will automatically update to reflect the new dimension.

2. Modification in the Parameters Dialog Box:

   • Go to the Manage tab on the ribbon and click on Parameters in the Parameters panel.
   • The Parameters dialog box will appear.
   • Find the dimension you want to modify in the User Parameters list.
