Which command would you use to apply taper or slope to faces, bodies, or from edges?

To apply taper or slope to faces, bodies, or edges in Siemens NX, the Draft command is the most appropriate choice. This command allows users to create an angular taper on the selected geometry, which is essential in various manufacturing processes where specific angles are required for parts to fit together or for the efficient production of components.

Using the Draft feature, you can specify an angle relative to a reference direction, making it easier to control how the slope is applied to the surface. This is particularly useful in injection molding or die-casting processes, where draft angles are necessary to remove parts from molds without damaging them.

Other options, while useful in their own right, do not specifically offer the functionality of creating tapered features. For instance, the Soft Blend command is used to create smooth transitions between surfaces, while Chamfer is intended for creating a beveled edge on a corner, and Face Angle generally refers to modifying the angle of a face without the specific application of taper. Thus, when it comes to applying slope or taper, the Draft command is indeed the most effective tool in Siemens NX.
