Which one of these is not a type of creation in the Face Blend command?

The Face Blend command in Siemens NX is utilized to create a smooth transition between faces in a model. It offers various options for blending:

1. Two-face blending allows a blend to be generated between two selected faces, creating a smooth transition.

2. Three-face blending extends this by integrating a blend among three faces, which helps in achieving complex surface transitions.

3. Feature Intersection Edge is another option that creates a blend based on the intersection of features, enabling intricate designs where multiple features meet.

The option labeled as "Face and Vector" does not represent a recognized type of creation within the Face Blend command. As such, it does not align with the established functionalities of this tool in Siemens NX, which focus specifically on utilizing more direct relationships among faces. The inclusion of options centered around specific face interactions contributes to the versatility of the Face Blend command, while “Face and Vector” does not conform to this approach, emphasizing the role and capabilities of the other options.
