11.9 Determining a point in relation to an axis
11.9.1 The principle of "Point in relation to axis"
The application "Point in relation to axis", can be used to determine the position of a point (e.g. a reference point) in
relation to the axis. In addition, points parallel to the axis, at right angles or at any desired angle to it, as well as points
on the existing axis, can also be defined. This application is useful, above all, for example, when nails are to be placed
on batter boards to indicate parallel axes on the site.

The application is performed in two steps:
1.
Defining the axis.
2.
Selecting or measuring the reference point.
If the station has been set up in coordinate / graphical mode, the axis and the reference point can be determined
directly from the data in memory.
If the station has not already been set up, the axis must be determined by measuring its starting point and end point.
The reference point is also determined by way of direct measurement.
11.9.2 Determining the axis
Measuring or selecting the first point on the axis
Measuring or selecting the second point on the axis
Shifting the axis
The axis starting point can be shifted in order to use a different reference point as the origin of the coordinate system.
If the value entered is positive, the axis is moved forward. If it is negative, the axis is moved back. A positive value
shifts the starting point to the right and a negative value shifts it to the left.
