Fuselage cross-sections may be rotated about the component X, Y, or Z axes around the center of the cross-section. The locations where feature lines pass through the cross-section may also be rotated along the section curve by using the Spin parameter. This tutorial demonstrates how to enter the desired cross-section rotation angle in degrees and how to use Spin effectively. Note that Skinning controls the feature line curves passing through the section and the skinning angles are defined in reference to that section. This means that by rotating a cross-section, you also effectively alter the physical direction of the feature line. Spin further affects this by altering the curve location where the feature lines are placed.
