Targets are used to check your design against the requirements of the project brief in real time while you model. You can set targets for quantity and size of an area type.
Targets are edited in the Metrics settings menu under the area type tab
Note: Targets only appear when using the Assigned area type metrics calculation
Target size per unit is displayed in the Targets
tab of the Area types
section of the metrics sidebar. The number of areas (if any) that are outside the target threshold are displayed beside the target size.
