The integration of supporting virtual engineering methods into 3D-CAD based development processes in the automotive industry leads to increased requirements, concerning the software packages as well as regarding the applied procedures and strategies. Modern IT-based engineering tools offer much more than the conventional development methodologies in component generation and digital mock-up processes. The trend definitely leads toward simultaneous CAE - support during the layout and design phases, attendant quality and structural management and the implementation of external data sources and receivers into the product development. It is up to the engineers to tap the full potential of virtual engineering processes regarding time reduction, error prevention in early phases and through technical modifications, whereas the applied methods and strategies represent a key factor on the way to efficient progresses. Integrated 3D-CAD design strategies in vehicle and engine development processes are based on the application of parametric-associative methods in geometry creation procedures at component as well as at assembling levels. Shortened project phases in combination with increasing numbers of product variants call for highly flexible virtual models across Integrated 3D-CAD Design Strategies in Vehicle- and Engine Development Processes the entire development phase. The functionalities of external parameter control in combination with smartly designed only spreadsheet non CAD based data collectors enable the generation of easy to handle virtual models for concept studies, for the assessment of variants and for a quick generation of geometry based components for further development steps. Programming macro based routines within the CAD models gives the possibility to automatically execute repeatable standard functionalities. Parametric-associative design methods in automotive development processes only work with a high efficiency, when they are well structured and planned. It is essential to predefine start up models for all components of the construction, considering the requirements of different types of parts regarding their geometry creation and their manufacturing characteristics. All these structure related tasks form the basis of an effective work within the boundaries of modern PLM systems. The far reaching possibilities of state of the art CAD software packages can only be utilized with a high efficiency, if the applied design methods and strategies consider the requirements of modern parametric development cycles. In this way, the presented approaches are able to support automotive engineering processes right from the initial stage.
