    The direction is picked freely.

  X/Y/Z

  The direction is fixed to the world X, Y, or Z axis.

• UVN

  Each face or edge extrudes in the direction based on UVN coordinates.

• Direction

  The direction is picked freely.

V (Boundary edges only)

Boundary edges extrude along the extending direction of the faces.

N

Faces extrude along vertex normal directions.

Boundary edges extrude perpendicular to the faces.
