  • Tool determines the orientation (strike azimuth, dip azimuth, dip) of a plane defined by three points.
  • 0 < dip < 90 degrees (clockwise down from horizontal; on the right looking along strike)
  • 0 < azimuth < 360 degrees (+ve clockwise from North)
  • -1 000 000 < coordinates < 1 000 000 m or ft
  • Elevation is +ve up; depth is +ve down.
  • -10 000 < elevation or depth < 10 000 m or ft
