The prompt
Create a precise 3D mechanical CAD model of the mounting bracket shown in the attached engineering drawing. Mode: Mechanical Engineering CAD / Precision 3D Modeling. Requirements: Reconstruct the part using the top, front, and side orthographic views. Match the isometric reference image. Create a single watertight solid with a stepped rectangular base, raised end plates, rounded central lug, curved connecting surfaces, and all indicated holes. Reproduce the two Ø0.75-inch through-holes in the upper plate and the Ø1.25-inch through-holes in the main lug and end plate. Apply the specified R1.25-inch radii and preserve all dimensioned offsets, thicknesses, heights, and hole-center positions. Use the drawing dimensions exactly, in inches. Do not guess missing dimensions or distort the geometry. Build an editable parametric model using sketches, extrusions, fillets, and Boolean hole cuts. Verify alignment between all three orthographic views and check that every hole passes through the correct feature. Display a clean isometric preview and provide editable CAD geometry. Export STEP (.step), STL (.stl), and the native CAD file if supported. If any dimension or geometric relationship is ambiguous, identify it and request clarification rather than inventing a value. Final result: A dimensionally faithful, clean, editable 3D engineering model suitable for CAD review and further manufacturing preparation.
