The Bounding Box agent expresses a preference for all shapes of a certain zoneType to fall within a theoretical box of editable dimensions.
A design's unfitness as evaluated by AgentBoundingBox is a weighted cumulative total of the amounts by which the all the shapes of a certain zoneType, taken together as a unit, exceed the boundaries of the established bounding box. If they all lie entirely within the bounding box, the reported unfitness is 0.000. If a design contains no shapes of the zoneType in question, this agent is ignored and its evaluation will not figure in the design's overall unfitness.
The Bounding Box agent is good for determining a region of the overall design in which you would like shapes of a certain zoneType to reside.
If you choose to edit this agent, you will be presented with this dialog box.
Note: AgencyGP's Z dimension is up/down. It corresponds to Maya's Y dimension.
