In the VB API, the set of relations on any model or model item is represented by the IpfcRelationOwner interface. Models, features, surfaces, and edges inherit from this interface, because each object can be assigned relations in Creo Parametric.

Methods and Properties Introduced:

The method IpfcRelationOwner.RegenerateRelations() regenerates the relations assigned to the owner item. It also determines whether the specified relation set is valid.

The method IpfcRelationOwner.DeleteRelations() deletes all the relations assigned to the owner item.

The property IpfcRelationOwner.Relations returns the list of initial relations assigned to the owner item as a sequence of strings.

The method IpfcRelationOwner.EvaluateExpression() evaluates the given relations-based expression, and returns the resulting value in the form of the IpfcParamValue object. Refer to the section The ParamValue Object in the section Dimensions and Parameters for more information on this object.
