Below shows how one would create a landmark Relative to the Global Coordinate System (Lab). In this case, a landmark called Ostacle_Top_Surface is created relative to the Lab's coordinate system with offsets of 0.0 for X, 0.7 for Y, and 0.45 for Z. These offsets are in metres.

Landmark Name: Ostacle_Top_Surface Starting Point: Define Orientation Using: Check Existing Segment: Lab Landmark Offset from Start Point or Segment Origin Offset Using the Following ML/AP/AXIAL Offsets X=0.0 Y=0.7 Z=0.45 Do Not Check Offset By Percent Do Not Check Calibration Only Landmark
