The aircraft cabin geometry is essential at many stages of the aircraft design process, ranging from preliminary design to detailed virtualisation. At each stage, for analysis purposes, a geometry model with an appropriate fidelity level is required. The aircraft cabin includes full-height components like closets, galley, and lavatory. This paper proposes a methodology, which derives CAD geometry for aircraft cabin full-height components from a set of design parameters at multiple distinct fidelity levels. Based on the complexity and for demonstration purposes, the galley model is selected.The galley's parametric description is based on data provided by the Common Parametric Aircraft Configuration Schema (CPACS), an established data model for aircraft design, and enhanced by component-specific parameters. The multi-fidelity model is the combination of low fidelity and high-fidelity models based on this description. The CAD geometry generation has been implemented using the Open Cascade Technology (OCCT) library. The multi-fidelity model provides consistent CAD geometry according to the model generation requirements of different disciplines based on the same set of parameters. The approach presented helps to accelerate multi-disciplinary design cycles, as tailored geometry with as little overhead as possible is available for disciplinary model generation. The CAD geometry generated in this model can be applied to experience aircraft cabin designs in virtual reality or to analysesthe dependencies between the aircraft cabin components and other systems. Furthermore, it can be used to validate the proposed enhanced cabin schema containing more detailed data about the cabin components.
