Abstract: Using an input device of a computer system, a graphic drawing is defined to include at least one graphic component. The graphic component is subject to a plurality of constraints. At least one of the constraints is redundant with respect to the other constraints. Approximate linear equations are substituted for the constraints. A subset of the equations are selected to determine a converging solution for the redundantly constrained graphic drawing.
