Set Out Line In this chapter •
Setting out points along a line, in either the horizontal or vertical plane
•
Checking that points are on a defined alignment
This function can be used for setting out and checking alignment of curblines, construction boards, and grades of pipes. A baseline or an offset from that baseline can be defined and its points set out in the field. Alternatively, a baseline can be established from which observations are described, allowing points to be set along the line of an offset. Plan view

Figure 15: Setting out a line
17.1 Defining the Baseline The SRX allows several methods of defining the baseline when setting out a line. The usual method for defining the baseline is to specify two points. However, you also can specify one point plus an azimuth, or a grade or vertical angle, to allow the setting out of points along the defined line.
