METHODS OF 3D-MODELLING WITH PARAMETRIC CAD-SYSTEMS OF THE NEWEST GENERATION

摘要

The authors are searching for new ways of using CADsystemsin the engineering design process. This contentsamong others the creation as well as the refreshing andcontinued handling of computer-based, three-dimensionalproduct models to be built as prototypes on the department'sRapid Prototyping machine [1, 2, 3].In spite of the many advantages of the C-technologies, onseveral areas a deficit in its dissemination and effective usagestill is noticed.The following paper will give an overview on how theparametrical, feature based 3D-CAD-modeler may support theengineering design process. It is described, which functionalitythe parametric functions of these modelers are offering to theuser and how the work with parametrical CAD-systems isstructured. Advises are given for a more competitiveimplementation and time saving work with these systems.
