The Lock Area feature allows you to lock a specific area chosen by the Selection tools. Once the data area is locked, further scanning will not affect the shape of the locked area, but the color. This feature is useful when you need to preserve the retracted gingiva data scanned after cord removal.
 How to use
1. Go to the Tools section and click Lock Area.
2. Select the area you wish to lock by using the selection tools. The selected area is indicated by a different color.
- To unlock the area you have selected, click the Clear Selected Area button.
- To unlock all areas, click the Clear All button.
