• Component Interfaces—Compares component interfaces from two components. Every pair of interfaces with the same name is taken as a referenced pair. The new model is automatically placed in the same position using the interface constraints. This option is efficient when the same name is given to similar interfaces configured in each component.

• Same Name (and Type)—Extracts references that have the same name and type to use as pairing criteria. This is the most powerful autopairing rule. Intent is clearly defined and each reference is replaced by a reference of the same name and geometry. Component replacement is automatic and unambiguous. This option depends on careful planning since geometric features must be consistently named throughout your projects.

• Same History—Looks for copied data sharing features from the existing component in the incoming component. Such features are then automatically used as pairs. When a feature is copied more than once, you are notified and must choose the correct reference. Use this method when the component is replaced by a copy of itself created when you use Save a Copy. Tags are evaluated until a difference between the original component and the copy is encountered.

• Same Parameters—Defines the type of reference and parameter name, type and value (use of wildcards is allowed). The system searches all references with the given parameter name, type, and value, and automatically pairs those that match.

• Same ID (and Type)—Compares items based on item ID and type. Comparison is sequentially starting from the lowest ID encountered in the outgoing component.
