The prompt
Create a parametric CAD model of a small cast aluminum engine cylinder housing. Overall dimensions: - Width: 50 mm - Length: 30 mm - Height: 60 mm Main features: - Rectangular crankcase body, 100 x 90 x 70 mm. - Cylindrical upper bore centered on the top face. - Cylinder outer diameter: 55 mm. - Cylinder height above body: 40 mm. - Central through bore diameter: 45 mm. Mounting features: - Four corner mounting bosses. - Four bolt holes, diameter 6 mm. - Bolt pattern approximately 75 x 75 mm. Side features: - Large circular intake opening on one side, diameter 35 mm. - Several machined pockets and reinforcement ribs around the body. - Fillets on all external edges, radius 2-4 mm. - Cast aluminum appearance. Requirements: - Generate as a solid parametric CAD model. - Exportable as STEP (.stp). - Mechanical engineering style geometry. - Symmetric design where possible.
