The survey figure prefix database contains information to determine the layer that a figure is drawn on, how a figure is stylized, and whether figures are created as breaklines and lot lines.
When figures are imported or created, they are matched based on their names and the prefix names. When a figure is created and its name is matched with a figure prefix, the figure prefix properties are assigned to the new figure, such as a layer name.
Figure prefixes are also used to determine linework connectivity when you use the Process Linework command. Any point that is coded with a name that matches a figure prefix is treated as an active feature. The Process Linework command may begin a figure when it encounters a prefix match if there is not an active figure with the same name and if the current Linework Code Set setting Automatic Begin On Figure Prefix Match is set to Yes.
