Change Parametric Dimensions
You can change the sizes of a geometry by double-clicking the relevant feature entry or by right-clicking the corresponding parametric dimensions in the drawing and choosing the Change parametric dimensions function.
Enter the new value or a new formula and press Return to confirm your entries.
If you have activated the 
Automatic recalculation, the changing takes place immediately. If you have deactivated this setting, the change will be marked with a 
symbol before the name of the feature. The new value will only be taken over after the next recalculation. An exception to the rule is the changing via parametric dimensions. These changes are, independent of the settings in the feature configuration, always applied immediately.
