CodeDesigner is a handy RAD tool designed to help you create various diagrams with ease describing applications' structure and logic (class diagrams, state charts, ...) and for generation of production-ready source code from them. In contrast to other similar CASE tools the CodeDesigner is aimed to generation of production-ready source code from supported diagrams. It means that not only application skeleton can be generated from diagrams but complete full-featured application including its entry point (main function) can be produced by a one click. The supported diagrams are: UML class diagrams, simple state chart, hierarchical (UML, Harel) state charts.
