The Design Specs page allows you to apply design specifications during Summary. By default, Design Specs are on, but none are active. You have to select the design specifications you would like applied during Summary.
Design specifications are set active by selecting (highlighting) the design specification description, then clicking once with the secondary mouse button to display the Toggle Active selection.
Once you select Toggle Active, a check mark appears in the Active checkbox for each selected design specification.
Note: If Design Specs are Off, the window showing the design specification descriptions is not shown.
