How to determine the center line with compass
Centering is to measure and determine the line position of the building's sitting direction and door direction, and set the compass in the center of the building.
It is necessary to bounce or pull the line through the reticle in the center of the building plane to make it coincide with the ten lines in the center of the compass, and the direction of the reticle should be parallel to the building wall.
In this way, when the inner disk rotates, the sitting direction of the building can be known through the reticle or the celestial center.
