About Collapsing Geometry into Import Features
You can collapse features and geometric entities, including solid features, into standard or neutral import features or independent geometry features. Collapse operations are valid in standard part and assembly modes. To collapse geometry into an import feature, you must select the import feature as the target feature and other geometric entities and features and click Model > Editing > Collapse. The selected geometry and features collapse into the target import feature.
You can collapse geometry into curve-type import features, but you cannot collapse geometry into facet type import features. However, the geometry selected for collapse can include facet features. Selecting a target feature and a solid feature collapses all other solid features of the part model into the target feature.
In addition to the geometry you select to collapse, the application also selects additional geometry and highlights all the selected geometry. The highlighted geometry and features are then moved into the target feature. You can no longer individually select the collapsed geometry.
The target features into which you collapsed all other features retain their feature IDs. The collapsed features lose their parametric properties and their parent-child relationships. They also lose the information about their layer assignments. Features with driving dimension annotations lose their driving dimension annotation elements. You cannot transfer feature relations and feature-level parameters to the import features.
However, the collapsed features retain their feature and entity IDs and maintain their references. Their entity-level parameters and the Associative Topology Bus (ATB) link information are preserved. The import profile settings, the details of the layer import status, and the layer filter information of the target features are also preserved. You can use Import DataDoctor (IDD) to modify the geometry of the import or the independent geometry features.
You cannot collapse geometry in the following environments and contexts:
SheetMetal Design
Manufacturing
Cabling
Simplified representations of parts
Parts with family tables defined
Family table instance parts and assemblies
Assembly-level holes and cut features
Models with Pro/PROGRAM defined
