NOTE
The vertical layout always uses three-dimensional point descriptions. In layouts with control lines and layouts with
coordinates, the line, height and offset dimensions are used.

The other screens shown are the same as described in the previous section.

11.3 As-built

11.3.1 The principle of "As-built"

In principle, as-built measurements can be regarded as a reversal of the horizontal layout application.
With as-built, existing positions are compared with their positions on the plan and the deviations shown and recorded
accordingly.
Depending on how the station has been set up, the plan data or, respectively, the positions to be compared, can take
the form of dimensions, coordinates or points in graphics.
When plan data in the form of CAD drawings can be transferred from a PC to the total station and the applicable
graphical points then selected from the display of the tool, so working with long numbers or lots of numbers is no
longer necessary.
Typical applications are checking walls, columns, formwork, large openings and much more. These jobs are done
by comparing positions on the plan with actual points on the object and displaying or, respectively, recording the
differences.
The "As-built" application is started by way of the corresponding button in the in the application menu.
Difference in height. dH = height (measured) – height

Difference in coordinate easting based on the coordin-
ate reference system. dE = delta east (measured) –
