The Core Feature command extends 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.

Core features can have different shapes. The Core Feature dialog box that appears displays the Prism
icon as the default shape to be created.
