# Fusion motion preview

Use Drive Joint on the three named joints, or run CAD/Set_Pose.py from Fusion's Scripts dialog.

| Joint | Value | Result |
|---|---|---|
| 01 COARSE | +60 to -18 mm | Carriage X = 22 to 100 mm |
| 02 FINE | 0 to +6.5 mm | Advances the pressure jaw |
| 03 KEY | 0 to -4.2 mm | Lifts the locking key |

Retract the fine jaw before lifting the key. Lift the key before sliding. With the key lowered, choose carriage X = 22, 28, 34, ... 100 mm. Do not drive the jaws past closed contact.

Drive Joint does not enforce the physical locking-key interlock or workpiece contact. Bolt translation is coupled to the jaw for visualization; thread rotation, force and wear are not simulated. In the real assembly, loosen the bolt and retract the pressure jaw manually.

The pictorial PDF is the physical assembly guide. These software controls are documented separately to keep the assembly steps visual.
