Stores the current approximate arc length for revision clouds.
| Type: | Real |
| Saved in: | Registry |
| Initial value: | 0.0000 |
When REVCLOUDARCVARIANCE is set to 1, the stored value is used to calculate the minimum and maximum arc lengths for revision clouds.
- Minimum arc length = value x 2/3
- Maximum arc length = value x 1 1/3
If REVCLOUDARCVARIANCE is set to 0, the stored value is used as the actual arc length for revision clouds.
