The prompt
Create a dimension-controlled 3D CAD prototype for ALTERA V1, a modular artificial nail system. COMPONENT: Size 7 decorative top nail with an integrated underside rail. NAIL SPECIFICATIONS: - Size: 7 - Overall length: 15–17 mm; use 16 mm nominal - Maximum width: 11 mm - Free-edge width: 7.9 mm - C-curve radius: 6.1 mm - Apex height: 0.69 mm - Apex position: 35% of nail length from the cuticle end - Apex thickness: 0.48 mm - Free-edge thickness: 0.23 mm - Sidewall angle: 12 degrees UNDERSIDE RAIL — V1: - Position: centered on the underside of the top nail - Rail width: 1.80 mm - Rail height: 0.50 mm - Rail length: 4.00 mm - Rail offset: 0 mm - End stop: 0.20 mm - Place the rail on the lower-facing surface of the decorative top nail. - Keep the rail aligned with the nail's longitudinal centerline. - Make the rail dimensions editable parameters. - Model the end stop as a distinct geometric feature and flag its exact orientation for confirmation. CAD REQUIREMENTS: 1. Generate a smooth, curved nail top with the specified dimensions. 2. Integrate the rail into the underside while preserving the nail's specified outer surface. 3. Avoid unintended intersections, zero-thickness geometry, and invalid solids. 4. Provide top, side, front, underside, and isometric views. 5. Provide a dimensioned technical drawing and an STL export.
