A Child Rule is a special type of Rule that creates a Child. Child Rules are defined in the Child Context Tab. Child rules are responsible for deciding the following:
1.The Design of the Children
2.The quantity of Children
3.The Parameters for the Children
Even though can have many elements, Child Rules are still treated internally (and for the purposes of Dependency tracking, etc.) as a single ‘Rule.’
Above, the Child Rule Quantity of EngineCylinder Children is determined by a Rule in the Engine named NumberOfCylinders.
The displacement value for the individual EngineCylinder Child is driven by a Rule called Displacement whose value is determined by the Engine’s TotalDisplacement Rule value divided by the Engine’s NumberOfCylinders Rule value.
