A framework of computational design method and modeling has been proposed for the layout and geometry design of complicated mechanical systems, which is named "configuration network and its viewing control" in the first report. In this paper, we present a geometric modeling technique with the aim of its integration with the framework. In the modeling method, each geometry of an object entity is represented with a geometric primitive or a set of ones, and they are manipulated through form features such as positions, directions and dimensions, which are represented with symbol-based algebraic expressions. The restrictions and desirable states imposed by configurations on an artifact are translated into mathematical functions among the features, and those variables are fixed by an optimization calculation in order to embody the configurations into actual arrangements and geometries. Moreover, this model has an ability to partially analyze the consistency of configurations among geometric primitives with symbol-based algebraic expressions. Finally, some examples of its applications are briefly demonstrated in a design problem of air-conditioner units.
