Tip: Setting the Second Constraint Definition
If you use the shortcut menu to set the tangent types, there is an easy way to set secondary types. Right-click the tangent and select the secondary type for the tangent, then right-click again and choose G1 - Surface Tangent, G2 - Surface Curvature, G3 - Surface Acceleration, or Draft Tangent. The original tangent type becomes the secondary type.
