End Areas
Function
There are two types
of end areas: cut area and fill area. This command allows you to
digitize both cut area and fill area on the drawing and writes data to
a .ew file. The command first prompts you to
calibrate the section sheet by picking three points and
specify their offsets to the centerline and elevations in order to
determine the horizontal and vertical intervals .Corners on the section
grid are preferred reference points. Then it prompts you to digitize
the
cut area and fill area respectively. Place your
cursor at one end of the end area and begin digitizing
the outline of the area. At the end of the section line,
press Enter on your puck or
keyboard. The end area is completed, and its area is printed on the
command line, and you are prompted to digitize
next end area. After you finish all the end area at one station,
accumulated cut area and fill
area are computed and printed out on the screen. All data of cut area
and fill area at every station would be
saved in the area file (.ew) that you have specified.
