How to use Leveling assistant

Measure

1. 1

   Reach a target slope

   Slope: set a target such as level, a drainage fall, a 1:12 ramp, or a pipe fall per foot. Lay the phone flat along the slope, or on a level, and raise the end the screen shows until it reads On target.

2. 2

   Measure a surface profile

   Profile: fix the phone to a straightedge, set the contact-point spacing, and add a stable reading at each marked span. The chart estimates relative humps and dips; share the CSV. Error can accumulate.

3. 3

   Level a surface or trailer

   Surface and Trailer: use Surface for tables and appliances on four feet, or Trailer for caravans and trailers on two wheels and a hitch. Enter the size, lay the phone flat with its top edge toward the front, and raise each foot, wheel or the hitch by the amount on the drawing. ⋮ › Screen layout switches between the 3D view and the side views.

4. 4

   Correct for the phone’s mounting

   Choose Calibrate in the ⋮ menu if a case or camera bump tilts the phone: take one reading, turn the phone around on the same spot, and take another.

Save

5. 5

   Recheck and save the adjustment

   Pick what you are leveling in the Job field. With the buttons at the bottom, mark a steady start, adjust, and Recheck, then save the before/after result. On Surface, Match surface takes the current reading as the target, or turn on Target lock. Check accuracy is in the ⋮ menu.
