The Chamfer tool in Autodesk Inventor is primarily used to form an angled edge between two surfaces, which is why it is the correct choice. This tool helps in modifying the geometry of the model by cutting away the sharp corners, which improves aesthetic appeal and reduces stress concentration in the part. By creating a beveled edge, the chamfer can also facilitate assembly processes and enhance the flow in manufacturing.

The functionality of the Chamfer tool is particularly useful in various applications, such as in preparing parts for welding or when designing components that need to fit together snugly. While the other options present different operations—creating rounded edges, adding draft angles, or increasing surface area—the Chamfer tool specifically targets the formation of angled edges, making it an essential feature in mechanical design and engineering.
