Cut out the 2 markers A and B. (6cm x 6cm).
Position Marker A at the top left and B at the bottom right.
When positioning the grid, visualize the Marker-A for a few moments, and a red circle will appear (this may take a few seconds). The grid configuration switches to parallel mode.
Then visualize the Marker-B. The application will draw a line between the 2 and position the grid in the center. You will be in parallel mode and you can set the height of the grid relative to the plane.
