ViaCAD 2D employs a dimension and constraint engine that solves linear equations related to CAD geometry. You can use this feature to rapidly explore different sketch geometry including associating area based Bill of Materials calculations. Plus you can create variables that are a function of dimension values. In this demonstration, we animated a dimension value driving not only a sketch but a crosshatch area value.
