This registry entry changes the behavior of the level command slightly; it keeps the other two axes as close as possible to what they were while leveling the selected axis. If there is a problem with leveling during alignments, then the value can be set to False (0) to turn off the new behavior. Normally, unless there is a problem with the alignments, this registry entry should be set to True (1).
Entry Name: AdjustLevelCommandRotation
Entry Type: Whole number that specifies True (1) or False (0). The default value is none (-1). The default value is True (1) when using a portable device.
