About Editing the Geometry of the Import Features
While you cannot selectively replace the geometry of import features or selectively add geometry to the import features, you can use the editing tools on the Import tab to edit the reloaded or replaced geometry of the import features to suit your requirements. You can use the editing tools to retain or remove surfaces and entities of the reloaded geometry.
The Import tab allows you to access the following editing environments depending on the geometry type of the imported features:
Import Data Doctor (IDD) for standard and curve-type import features.
—Facet environment for facet import features.
When you reload a source file or add geometry from a file that consists of standard 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 new node.
While reloading geometry, you can click on the Import tab to access IDD and edit the geometry of the new node in IDD as follows:
Delete data that you do not require from the new node.
Delete the original surfaces that you want to replace with the new surfaces.
Sew the newly added surfaces into the old quilts as required.
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, editing changes are lost when you update the model using Associative Topology Bus (ATB).
When the import feature consists of facets, you can click on the Import tab to enter the Facet environment and use the facet editing tool to edit the import feature. While editing point cloud data, you can click Points > Wrap to wrap the point data and create triangulated features. You can then use Wrap > Facet to complete and refine the facet feature. Use Facet > Make Manifold to create an open or closed facet model with all the triangulations continuously connected by their edges.
If you delete reference entities or the entity IDs of ATB-enabled import features while using the Import DataDoctor or the facet editing tool, you are warned 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 incomplete reference pair matching.
