12. Create **Lead-in 1**, a frustum with bottom radius 2.8, top radius 4 and height 3, base center (0, 0, 21).
13. Create **Insert pilot 2**, radius 2.2, height 15, initially along +Z, with its base center at (34, 0, 10).
14. Create **Push access 2**, radius 1.2, height 12, initially along +Z, with its base center at (34, 0, -1).
15. Create **Lead-in 2**, a frustum with bottom radius 2.8, top radius 4 and height 3, base center (34, 0, 21).
16. Create **Mount -51 -17**, radius 2.6, height 10, initially along +Z, with its base center at (-51, -17, -1).
17. Create **Head -51 -17**, radius 4.5, height 3, initially along +Z, with its base center at (-51, -17, 3).
18. Create **Mount -51 17**, radius 2.6, height 10, initially along +Z, with its base center at (-51, 17, -1).
19. Create **Head -51 17**, radius 4.5, height 3, initially along +Z, with its base center at (-51, 17, 3).
20. Create **Mount 51 -17**, radius 2.6, height 10, initially along +Z, with its base center at (51, -17, -1).
21. Create **Head 51 -17**, radius 4.5, height 3, initially along +Z, with its base center at (51, -17, 3).
22. Create **Mount 51 17**, radius 2.6, height 10, initially along +Z, with its base center at (51, 17, -1).
23. Create **Head 51 17**, radius 4.5, height 3, initially along +Z, with its base center at (51, 17, 3).
24. Subtract **Insert pilot 0**, **Push access 0**, **Lead-in 0**, **Insert pilot 1**, **Push access 1**, **Lead-in 1**, **Insert pilot 2**, **Push access 2**, **Lead-in 2**, **Mount -51 -17**, **Head -51 -17**, **Mount -51 17**, **Head -51 17**, **Mount 51 -17**, **Head 51 -17**, **Mount 51 17**, **Head 51 17** from **Insert bridge blank**, consuming the tools; name the result **Heat-insert bridge**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Insert 1 pilot radius | 2.2 | 1.9–2.6 | 0.05 | Pilot radius for a physical insert fit trial; the fixed lead-in is larger. |
| Insert 2 pilot radius | 2.2 | 1.9–2.6 | 0.05 | Pilot radius for a physical insert fit trial; the fixed lead-in is larger. |
| Insert 3 pilot radius | 2.2 | 1.9–2.6 | 0.05 | Pilot radius for a physical insert fit trial; the fixed lead-in is larger. |

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.
