The prompt
Create a parametric 3D mechanical assembly of the Universal Joint shown in my reference drawing. Treat the uploaded reference drawing as the ultimate source of truth. Reproduce the geometry, proportions, component arrangement, and relative positions shown. Model the two yokes/forks, central cross-shaped spider, four bearing-pin ends or bearing caps where shown, and connecting features according to the reference. Maintain correct alignment of the two shafts/yokes and the perpendicular cross-pin arrangement. Do not add unsupported features or dimensions. Use millimetres and expose major dimensions as editable parameters. If a dimension is missing or unreadable, flag it as unknown rather than inventing an exact value. Create a proper assembled 3D solid model, not a 2D drawing or a single simplified block. Apply neutral grey materials with slightly different grey shades for separate components. Set the presentation view to SE Isometric, with clean edges and a plain light background. Keep components as separate solids where possible. Export STEP and STL if supported.
