Abstract: Apparatus and method for a computer-aided design (CAD) system for dynamically switching from one CAD platform to another CAD platform. The invention includes building a library of generic CAD functions, each for directing a graphical manipulation process. Each one of the generic CAD functions is based on a platform-specific CAD function, there being a large number of common CAD functions among many different CAD platforms. The invention interprets received function calls and translates the call to a generic function call for invoking a generic CAD function. A processor then executes the generic CAD function, irrespective of the platform used to call the function.
