What type of chamfer cannot be created?

The type of chamfer that cannot be created is the Two Angle chamfer. In CAD applications like NX, specifically regarding chamfers, the common types include Distance Angle, Equal Angle, and Conic chamfers.

A Distance Angle chamfer is defined by a distance from the edge and an angle, which allows for flexibility in shaping the corner of the part. Equal Angle chamfers, on the other hand, create a 45-degree beveled edge by removing material equally from two adjacent faces. Conic chamfers can have a curved profile leading from one edge to another, adding a more complex transition.

However, a Two Angle chamfer traditionally requires the specification of two distinct angles, which is not a standard method recognized in typical chamfer features within most CAD software environments like NX. The standard functionality tends to focus on single angle definitions or equal angles, rather than allowing for two separate angle values for a single chamfer feature. This makes Two Angle chamfers impractical or unsupported within the NX capabilities, thus establishing it as the type of chamfer that cannot be created in this context.
