I BUILT A TWIN-ROTOR WANKEL ENGINE WITH OPUS 5.5. YOU CAN TAKE IT APART IN A BROWSER 81 parts, 9 components, 1,308 cc, the same displacement as mazda's 13b. explode it, cut it in half, click any component for its spec card. intake → compression → power → exhaust the rotor turns at one-third shaft speed, held by a 30-tooth ring gear on a 20-tooth fixed gear. two rotors fire 180° apart, so the shaft gets a power stroke every half turn. the hud tracks both angles live, and the rotor stays at exactly one-third of the shaft the whole run, which suggests the model built the mechanism first and the picture second. the takeaway is simple: prompt the mechanism, not the render. the geometry comes out right when the spec demands it.
