Abstract
Systems and Methods are provided for determining a position of an addendum mesh node disposed between a part mesh boundary and a binder mesh boundary with respect to a first plane. The method includes selecting a first point on the part mesh boundary and a second point on the binder mesh boundary having positions with respect to the first plane that are disposed on a control line which also intersects the position of the addendum mesh node with respect to the first plane, identifying a plurality of control points having positions with respect to the first plane that are disposed on the control line, and generating an interpolated curve that intersects the first point, the second point, and the plurality of control points. The method further includes adjusting the position of at least one of the plurality of control points with respect to a second plane that is substantially orthogonal to the first plane and repeating the step of generating the interpolated curve until the interpolated curve is tangentially correlated to the first point and to the second point. Finally, a position on the interpolated curve is identified that corresponds to the position of the addendum mesh node with respect to the first plane.
