End Areas
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.
