While you cannot selectively replace the geometry of an import feature or selectively add geometry to the import feature, you can use the editing tools available on the Import tab to edit the reloaded or replaced geometry according to your requirements. You can use Import DataDoctor (IDD) to retain or remove surfaces and entities of the reloaded geometry.

You can collapse features and geometric entities, including solid features, into standard or neutral import features or independent geometry features. You can then use IDD to modify the geometry of the collapsed features as they are part of the import or the independent geometry features after the collapse operation.

When you reload a source file or add geometry from a file that consists of standard or curve-type import features, all geometry that you add or reload from the selected file creates a separate node in the Geometry and Topology Structure (GTS) tree. You can then use the IDD editing tool on the Import tab to retain or delete surfaces and quilts in the new node. You can remove the surfaces and other entities in the original geometry and replace them with surfaces and entities from the newly node. You can also collapse features and geometric entities, including solid features, into standard or neutral import features or independent geometry features and use IDD to edit the collapsed geometry.

If the import feature is ATB-enabled, you must make sure that the import feature is made independent and is not ATB enabled before you edit the geometry. Otherwise, the editing changes are lost when you update the model using ATB.

If you delete reference entities or the entity IDs of ATB-enabled import features while using the Import DataDoctor, Creo Parametric warns you about the resultant incomplete reference pairs when you exit the Import tab, especially when the entities are parents of downstream features. You can then click Options > Reference Pairs Matching on the Import tab and complete the reference pair matching.
