If you are using a Huawei phone, if you want to measure the length of a straight line:

1. In the AR Measurement interface, tap the straight line.

2. Aim the lens at the plane where the measurement object is located and slowly move the phone to find the plane.

3. Move the phone so that the bullseye is at the starting point of the measurement object, and click the plus sign to add the starting point.

4. Slowly move the phone so that the bull's-eye moves along the edge of the object to be measured until it reaches the end point. Click the plus sign to complete the measurement.
