Determines the geometric representation used to compute aerodynamic forces.

## Items

| Name | Value | Description |
| --- | --- | --- |
| `Automatic` | 0 | Let the physics engine select the geometric representation for aerodynamic force and torque calculations. |
| `UseCollisionGeometry` | 1 | Use the current collision geometry specified by [`TriangleMeshPart.CollisionFidelity`](https://rapi.sleaze.dev/classes/TriangleMeshPart.md) for aerodynamic force and torque calculations . |
| `UsePreciseGeometry` | 2 | Force the engine to compute aerodynamic forces and torques using a more precise geometry representation based on the original mesh. This option may increase join and replication time if used on a large scale. |

## Used by
