About Changing the Tolerance Format
You can set the tolerance format using the default_tolerance_modeconfiguration option. To modify the tolerance format for individual dimensions, use the Value and Tolerance portion of the Modify Dimension dialog box. The following tolerance formats are available: Nominal Value, Upper Tolerance, and Lower Tolerance.
To make tolerances visible in the drawing, set the tol_display drawing setup file option to yes. Tolerance values correspond to those given in the table at the bottom of the window.
