Line/Arc Methods
Description
Segment a line
Calculates the coordinates of new points on
a line.
Elements that must be known are
•
coordinates of the start and the end
point of the line
OR
•
a bearing and distance from a known
point that define the line
AND EITHER
•
the number of segments dividing the
line
OR
•
a segment length for the line.
The coordinates of the known points
•
can be taken from the job.
•
can be measured during the COGO calcu-
lation.
•
can be entered.
