About Rule Bases

	Importing a Rule Base: Select the Insert Rules icon to import the rule base (expert rules and expert checks) of an external document into your current document. See also About Rule Bases.
	Solving a Rule Base: Select the Solve icon to solve a rule base and to apply the rules and checks contained in this rule base to your document.

A rule base is a feature located at the top of the Expert Rule/Check hierarchy
(see graphic below).

A rule base is automatically created when accessing the Knowledge Expert workbench.

Only one rule base can be added to a CATProduct or a CATPart. But a CATProduct with its rule base can refer to components having their own rule bases.

A rule base can be activated or deactivated. It can be made up of several rule sets. When a rule base is deactivated, the features below are deactivated too.

A rule base has no effect on a document until a solve operation is launched. The purpose of the solve operation consists in firing (or executing) the active relations in the active rule sets.
