AI CAD prompt: Twin-bearing shaft pedestal

Create a new owned Nora3D part document. Use millimeters, world XY as the base and +Z as height. Retain named native features and expose only the controls listed below.

1. Create **Base**, a 110 × 80 × 8 box, centered at X=0, Y=0, with its bottom at Z=0.
2. Create **Pedestal -24**, a 32 × 16 × 30 box, centered at X=0, Y=-24, with its bottom at Z=8.
3. Create **Ring -24**, radius 20, height 16, initially along +Z, with its base center at (0, -32, 38).
4. Rotate the current **Ring -24** solid -90 degrees around world X through [0, -32, 38]. Resolve the actual current entity ID before the operation.
5. Create **Pedestal 24**, a 32 × 16 × 30 box, centered at X=0, Y=24, with its bottom at Z=8.
6. Create **Ring 24**, radius 20, height 16, initially along +Z, with its base center at (0, 16, 38).
7. Rotate the current **Ring 24** solid -90 degrees around world X through [0, 16, 38]. Resolve the actual current entity ID before the operation.
8. Create **Side stiffener -28**, a 8 × 68 × 10 box, centered at X=-28, Y=0, with its bottom at Z=8.
9. Create **Side stiffener 28**, a 8 × 68 × 10 box, centered at X=28, Y=0, with its bottom at Z=8.
10. Unite **Base**, **Pedestal -24**, **Ring -24**, **Pedestal 24**, **Ring 24**, **Side stiffener -28**, **Side stiffener 28** as **Pedestal blank**. Require one connected result.
11. Create **Bearing -24**, radius 11.1, height 20, initially along +Z, with its base center at (0, -34, 38).
12. Rotate the current **Bearing -24** solid -90 degrees around world X through [0, -34, 38]. Resolve the actual current entity ID before the operation.
13. Create **Bearing 24**, radius 11.1, height 20, initially along +Z, with its base center at (0, 14, 38).
14. Rotate the current **Bearing 24** solid -90 degrees around world X through [0, 14, 38]. Resolve the actual current entity ID before the operation.
15. Create **Mount -44 -28**, radius 3.25, height 12, initially along +Z, with its base center at (-44, -28, -1).
16. Create **Mount -44 28**, radius 3.25, height 12, initially along +Z, with its base center at (-44, 28, -1).
17. Create **Mount 44 -28**, radius 3.25, height 12, initially along +Z, with its base center at (44, -28, -1).
18. Create **Mount 44 28**, radius 3.25, height 12, initially along +Z, with its base center at (44, 28, -1).
19. Create **Service window**, a 28 × 22 × 12 box, centered at X=0, Y=0, with its bottom at Z=-1.
20. Subtract **Bearing -24**, **Bearing 24**, **Mount -44 -28**, **Mount -44 28**, **Mount 44 -28**, **Mount 44 28**, **Service window** from **Pedestal blank**, consuming the tools; name the result **Twin bearing pedestal**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Front bearing radius | 11.1 | 10–12 | 0.1 | Front bearing seat radius, including measured fit allowance. |
| Rear bearing radius | 11.1 | 10–12 | 0.1 | Rear bearing seat radius, including measured fit allowance. |
| Service window width | 28 | 22–36 | 1 | Width of the central through-window in the base. |

All unlisted dimensions, topology and feature order remain fixed. Radius controls are radii, not diameters. These are independent numeric ranges; do not introduce unsupported formula bindings or assume a fit standard from an example value.
