Removing features from a model

To remove features from a model, use the Defeature Geometry command. When you defeature a model, you simplify geometry by using selections in the graphics window to remove a face or set of faces. This is a quick way to remove larger model features such as slots or bosses containing multiple faces.

To use Defeature Geometry, you must have the idealized part displayed in the graphics window.

To modify the idealized part, you must first either promote or WAVE link the body.

Each Defeature Geometry operation you perform is created as a modeling feature within the idealized part. You can view these features in the Part Navigator by right-clicking in an empty area of the Part Navigator and selecting Timestamp Order. Each feature appears under the Model History node as “Defeature Body (n).”

Selection intent

The Defeature Geometry command supports the use of selection intent options. You can use the selection intent options (located on the scene toolbar) to build a collection of faces to remove. For information about the selection intent options, see Selection intent rules and options on the scene toolbar.
