In the "Extrude" command, it was possible to reverse the direction of the extrusion. This allowed a cube to be created and able to configure each of the corners according.
In a single "Extrude" feature it was possible to do several bodies. Using NX2206, this forces the user to create several "Extrude" features with the same result instead of in a single feature.
This Directional vector in the Extrude using a "Line" was intentionally removed in the User Interface (UI). It can be toggled back ON with a setting in the Customer Defaults.
Customer Defaults --> Modeling --> General --> Show Section Curve Flow Direction
As you can see, this is toggled OFF by default.
