1. In a Computer Aided Design (CAD) environment, a method, comprising the steps of: providing a system model of a Micro Electro-Mechanical Systems (MEMS) displayed to a user in a schematic view, said model including a plurality of model components; generating a graphical three-dimensional (3D) view of said model depicted by the schematic view for display to the user; and cross-referencing said 3D view and said schematic view so that changes in the 3D view are reflected in the model components depicted in the schematic view and changes in the model components depicted in the schematic view are reflected in the 3D view.
