Creating a Core Feature

You can extend the internal shape of a cavity. A spatial volume replaces material volume only where the core feature intersects with the shellable or external feature within the same body. The core feature is most useful if you want to create a uniquely shaped shell with varying wall thicknesses.

Before you begin: Open a 3D shape representation with an External Feature.
