Rotation about the center of the tube.


Top and bottom radii of the tube.

Radius Scale

Uniform scale for the radius.


The height of the tube.


Number of rows in tube.


Number of columns in tube.

U Order

Order of NURBS/Bezier curve in U direction.

V Order

Order of NURBS/Bezier curve in V direction.

U Wrap
