Import and Export
-Create New Project
-Import job from the DBX folder on the SD card.

Managing Scans
-To select a certain scan expand the Scans drop down in the Navigator.
-Selecting a scan will highlight all points in the scan and will also display information on the right side
of the screen in the Property Grid such as Point Count and station setup.
-To check the total number of scan points in a project which has multiple scans you can add all the
scans to a group and then select the group which will give the total number of points.
-The easiest way to do this is to go to the scanning tab across the top and click new.

-Then across the bottom use the Inspector and select scanning, from here you can select one and
press control+a to select all or only select the scans you want to count.
-Right click and add to a scan group.

will display on the left the same as it did for one scan but will the total number of points selected in
the scan group.
