236 | Chapter 19 Adjusting Data and Working with Figures
By using figure names with figure prefixes, you can simplify the process of
turning observed data into lines and curves in a drawing. If you plan to query
a figure, such as perform a mapcheck on a figure that represents a particular
parcel, then you should give it a unique name. By referring to the figure
name, you can use the figure commands to do the following:
■ Continue a figure
■ Offset a figure
■ Inverse a figure to list its courses and area
■ Mapcheck the figure to determine its closure
■ List the figure area
Figure prefixes control which layer each figure is drawn on. You can establish
figure prefixes in the Survey Prefix Library. When you assign a name to a
figure and a prefix match is found in the Figure Prefix Library, the figure is
automatically placed on the correct layer.
Using the Survey Toolspace Figure Inquiry commands you can display the
figures, list figure names, and check the figure for closure information. For
more information see, Survey Toolspace and Panorama in the online Help.
Key Concepts
■ To begin a figure, either select Analysis/Figures ➤ Figure Creation or
type Figure Creation commands directly at the Survey Command Line.
You can also enter Figure commands and figure names directly into a
data collector.
■ All figures are polylines with extended entity data.
■ If more than one figure has the same name, then some commands may
not be able to find the correct figure. For example, to use the Centerline
or Baseline commands, a figure must have a unique name.
■ You can use figures as surface breaklines.
■ You can use figures to calculate closure information.
■ You can create figures by referencing observed points in point-to-point
mode (as if you were walking around the figure), or you can create figures
by entering data in cross section format. For example, you can collect
points for edge of pavement, centerline, and edge of pavement, and then
move up 50 feet and collect points for the next cross section.
