Sets the Variation Setting method.

By Auto Function : Interlocks curves from registered Auto Functions.

User Defined : The user defines the curve himself.

Select Auto Function : Select an Auto Function to interlock the curve. Only Auto Functions registered in the current mode can be selected.

Select Symmetric Plane : Select Constraint Plane to be applied as Symmetric Plane. Symmetric Plane means the location where the tangent of the variation curve is parallel to the X-axis.

Curve Direction : Sets the direction in which the curve is calculated from the Symmetric Plane.

Positve : The curve is calculated in the unit length direction of the current mode.

Negative : The curve is calculated in the opposite direction to the Unit Length of the current mode.

Variation Type : Select the type of variation of the curve.

Linear

Parabolic

Cubic

Polynomial

Order : Enter the order of the curve. It is activated only in case of ‘Variation Type : Polynomial’.
