Defines rollover values when adding a slope constraint. This feature is activated when you select the Rollover Values button on the Point Properties dialog box.

High side difference

specifies the maximum allowed slope difference between the vector from the reference point and the parent point and the vector from the parent point to the constrained point when the reference slope vector is positive.

Low side difference

specifies the maximum allowed slope difference between the vector from the reference point and the parent point and the vector from the parent point to the constrained point when the reference slope vector is negative.

Reference point

specifies the point that defines the reference slope.
