Fostering Model Consistency in Interdisciplinary Engineering by Linking SysML and CAD-Models

Model-based Systems Engineering emphasises the use of a consistent, connected system model as a central source for all relevant design information within product engineering. Next to the system model, additional domain-specific models are required to apply domain-specific engineering approaches. For an efficient interdisciplinary engineering process, these different models must be linked to avoiding inconsistencies. This contribution argues the need to link domain-independent and domain-specific models and presents challenges within an interdisciplinary engineering process based on spread design information within different models. Model elements within SysML and CAD-models are linked to support specific engineering activities and to address these challenges. Essential contribution is the introduction and application of a technical interface concept to link SysML and CAD-model elements.
