The module for CAD modeling of the part is the first module within the integrated CAD/CAE system. This module is used for generating CAD model of the plastic product and appropriate simulation model. The result of this module is solid model of plastic part with all necessary geometrical and precision specifications. Precision speci- fications are: project name, number, feature ID, feature name, position of base point, code number of simulation annealing, trade material name, material grade, part toler- ance, machine specification (name, clamping force, maxi- mal pressure, dimensions of work piece), and number of cavity. If geometrical and precision specification is speci- fied (given) with product model, the same are used as input to the next module, while this module is used only to generate the simulation model.
