Specifies the angle between two input geometries. This is effectively the angle between the two primary axes of the input geometries. When a new JointInput object is created, this value defaults to zero. When the joint is created this will become the value of the parameter that controls the joint angle.
 When using a real value to define the angle, the value is in radians. When using a string the expression is evaluated using the document default units for angles.
