Six families:
- NACA 4-digit aerofoils (e.g. `NACA2412 wing 200mm chord 600mm span`)
- NACA morph wings — interpolates two profiles along the span (`NACA2412 to NACA0009 morph 600mm`)
- Square-to-round ducts (`square 200mm to round 100mm duct 400mm length`)
- Columns — straight or twisted (`twisted column 200mm diameter 800mm height`)
- Stars with 3–24 points (`5-point star 200mm 400mm height`)
- Ellipses (`ellipse 200x100 mm 500mm length`)
