• Calibration:  Make sure the room is well lit.  The App needs to be able to see texture on the floor.  If it is dark or an all white ground, it won't detect well.
  • Calibration:  Make sure the area that you "calibrate" on is a flat surface and give the app a few seconds after detecting the floor before placing your first point.
  • Measuring:  PLNAR is optimized for rooms < 25' (<8 meters) long.  Accuracy will degrade beyond that.
  • Measuring:  Walk around the room at around 4-6 feet away from each corner/door and then place the points
  • Vertical:  When establishing ceiling height, it is best to pick the segment that maps to the seam
  • Time: The longer the AR session is the more prone the measurements are to drift.
