Multi-Scan measurements
Some measurements can't be made in a single scan. You might need to jump to a second scan, maybe even a third scan, and continue with the measurement there. This is possible with the multi-scan measurement.
1. Open the scan in which you want to begin the measurement.
2. In the Task Panel, click Measure Distance.

3. Start to pick the points that are accessible in the scan. To switch to another scan and continue the measurement there, do one of the following:
Click the scan icon and open the scan’s Panorama View.
Click any scan icon, click the Overview Map icon, click another scan icon and open the scan’s Panorama View.

Note: No points can be picked in the Overview Map itself since 3D points are required. The finished measurement also won't be shown in the Overview Map.

4. Continue picking measurement points in the next scans.

Clicking the button associated with a measurement point in the task step will open the Panorama View of the scan where the point was picked and focus the measurement in it.
To finish the measurement, continue with the next task steps, then click OK.
