Inverse with Area
This command generates a report of the angle and horizontal
distance between a series of points and calculates the area of the
closed figure defined by the points. The points can be entered
individually or by selecting a point group or linework entities. To
use a point group, type G for Group at the first prompt. To use a
linework, type L for Line at the first prompt. For linework, a
single closed polyline can be used or a series of connected lines,
arcs and polylines that are selected one at a time.
Curve data can also be entered and reported. The points can be
either picked on the screen, or entered by point number. You can
also enter a range of point numbers (i.e. 1-9). The closure is
reported using the total distance inversed, and the difference
between the starting and ending points, as the closure error.
At the first command prompt, you can enter O for Options to bring
up the command options. The
Input Methoddetermines the default input mode for the first
command prompt. The
Different Radius Tolerancechecks that the distance between
the PC and radius point and the PT and radius point match for
curves. The
Linework Snap Toleranceapplies to the linework input mode
and is used to check the distance between end points when
connecting two linework entities. The Report Closed By choosing
between using the difference between the starting and ending
coordinates to calculate the closure error or angle and distance
values in the report. The
Apply Compass Rule Adjustmentwill adjust the perimeter as a
closed loop for the closure error. The
Label Both Feet And Metersis an option to report the
distances in both feet and meters. The
Report Stationsoption adds stations for each point into the
report. The
Use Report Formatterchooses between the standard report or
customizing the report. You can also set the decimal precisions for
the report and whether to report stations for the distances along
the perimeter.
This command creates a polyline of the figure which can be erased
or kept in the drawing. The
Prompt To Draw Perimeter Polylineand
Polyline Layersettings apply to this polyline.
The area can be labeled in the drawing using the settings from the
Area Defaultscommand. If you don't want to label the area,
press Enter at the pick label point prompt.
