The Draft command is primarily used to apply what to faces?

The Draft command is primarily used to apply a slope to faces in a 3D model. This functionality is crucial in manufacturing processes, particularly when creating molded or cast parts, where draft angles are essential for ensuring that parts can be easily removed from molds without getting stuck. In engineering and design applications, applying a draft can optimize the design for assembly and production by enhancing the manufacturability of parts.

When using the Draft command, designers can specify the angle of the slope to achieve the desired contour and release angle for the part. This makes the command indispensable for users involved in product design and engineering, as it allows them to create features that adhere to manufacturing best practices.
