The prompt
Create a dimensionally accurate 3D CAD model from the attached three-view engineering drawing. The object is a vertical pedestal-shaped mechanical part with a hollow hemispherical bowl at the top (outer radius 1.00 in, inner radius 0.85 in, wall thickness 0.15 in), a narrow cylindrical connecting shaft, a central hexagonal connector with a circular through-hole (radius 0.10 in), a lower cylindrical shaft with a wider collar, and a rounded hemispherical bottom base (radius 0.50 in) with a flat bottom. The total height is 3.17 inches. Keep all sections centered on the same vertical axis. Reproduce the proportions, curves, holes, and details shown in all three orthographic views. Use inches and export as STEP and STL files.
Parameters
| Name | Value | Range |
|---|---|---|
| Outer Bowl Radius | 1 in | 0.5 – 1.5 |
| Inner Bowl Radius | 0.85 in | 0.4 – 1.4 |
| Total Height | 3.17 in | 2 – 4 |
| Bottom Base Radius | 0.5 in | 0.25 – 0.75 |
| Hex Through-Hole Radius | 0.1 in | 0.05 – 0.2 |
| Upper Shaft Radius | 0.25 in | 0.1 – 0.5 |
| Upper Shaft Height | 0.8 in | 0.2 – 1.5 |
| Lower Shaft Radius | 0.25 in | 0.1 – 0.5 |
| Lower Shaft Height | 0.5 in | 0.1 – 1 |
| Collar Radius | 0.45 in | 0.25 – 0.6 |
| Collar Thickness | 0.12 in | 0.05 – 0.3 |
| Hex Across Flats | 0.7 in | 0.4 – 0.9 |
| Hex Thickness | 0.25 in | 0.1 – 0.5 |
Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
