The linework code set (
Figure) lists what designators are used to start, stop, continue, or add segments to lines. For example, the B code that is typically used to begin a line can be replaced with an S, RT can be simplified to R for a right turn, and PC and PT can be used to begin and end curves. Linework code sets allow a survey crew to customize their data-collection techniques based on methods used by various types of software not related to Civil 3D.

Linework Option: Begin on Figure Prefix Match
There is a setting in the linework code set called Automatic Begin On Figure Prefix Match (as you can see in
Figure). If you select this option, lines will start when a shot description matches one of your figure prefixes (such as EP or CL in
Figure: The Figure Prefix Database Manager), with no additional coding needed.
Depending on your survey department’s method for picking up linework, Automatic Begin On Figure Prefix Match can be a good thing or a bad thing. If the survey crew has fastidiously collected each line with its own name, such as CL1, CL2, EP1, EP2, and so on, with no repeats, it can work well. If they use start and stop codes but reuse line names throughout the survey, it can produce figures that connect unintentionally.
