Chapter 49. Adjusting plane

Adjusting plane

This module serves to calculate the adjusting plane using the least squares method. The plane formula is calculated with the condition of the minimum sum of the square of the distances of the individual points from the plane. This condition can be completed with the additional condition of verticality of the plane.

Plane specification

The plane is determined using the spatial coordinates of the points. The points can be entered in the module from the keyboard or dragged from the coordinate list. You can add the points to the point list by pressing the button (Add), and remove them by pressing the button (Remove).

If you have checked the option Use for plane formula when adding the point on the list, the added point can be used to define a plane formula. If this option is turned off, the distance from the plane will be calculated for the point, but it won't be used for the plane definition. The points used for the plane definition are marked in the report with a star.

After calculating the plane, the distances of all the entered points from the plane are calculated.
