About the Inherited Reference Part
A reference model that is created using Inherited in the Create Reference Model dialog box, inherits all the geometry and features from the design part. Inheritance allows one way associative merge of geometry and feature data from a design part to the reference part. Initially, an inheritance feature has its geometry and data identical to the part from which it is derived. You can identify the feature data that you want to modify on the inherited feature, without changing the original part. Inheritance provides greater freedom to modify the reference part without changing the design part.
Inheritance Features Capabilities
Inheritance features capabilities include:
• Access to parameters and features of the inherited models and their usage, provided the prefix "IID_" is used for them.
• Access to dimensions of the inheritance features in drawing mode as well as part and assembly mode.
• Multilevel nesting of inheritance features.
• Support of Reference Pattern.
• Identification of the different systems of units being used by the reference part and the design part.
• Special resolve mode for inheritance failure cases.
• Ability to copy non-geometry elements in addition to 3D notes, surface finish, and so on.
• Parent-child relationship.
• Ability to change the inherited reference part to the instance/ generic of the family table.
• Ability to modify dimensions, features, references, parameters, tolerances, dimension boundaries, annotations (geometry tolerance, surface finish, 3D notes, 3D symbols) dependency, shrinkage by dimension, and so on, of the inherited model.
• Ability to modify all varied items except annotations, by defining associate parameters that can be accessed through the family tables.
• Ability to replace references from inside or outside the inheritance feature.
• Ability to specify shrinkage by dimension in the reference part, without affecting the design part.
• Different status for varied items (dimensions) such as Locked, Not Applied, Erased, Restored, and so on.
