Modify a Design Variable
- 
                To modify the Nominal value, click in the field and
                    change/edit the value. 
                 Figure 1. Figure 1.- Changes made to the nominal values using the Wizard will be reflected in the current MBS model.
- The bounds will be automatically updated using the default calculations.
 
- 
                To modify the Bounds, edit the Lower/Upper Bound fields
                    directly, or use the Bounds group provided at the bottom (see below) to quickly
                    modify multiple bounds at once.
                 Figure 2. Figure 2.- The Value method will add/subtract the number entered from the nominal value to calculate the bounds. The Percent method will add/subtract the specified percentage of the nominal value to calculate the bounds.
- The drop-down menu allows you to change the upper bound and the lower bound separately or change them both together.
