Build a simple vehicle from named components and check dimensions before adding detail. Vary one design parameter at a time and retain clear configuration names for comparisons. Inspect exported geometry and any analysis assumptions separately, because a useful conceptual shape is only the beginning of a complete aerodynamic or structural engineering study.
This is best suited to aerospace teams exploring aircraft concepts. Before committing a larger project, account for these trade-offs: specialized around vehicle geometry; detailed certification analysis needs other work.
