Bearing-Distance Use the bearing-distance subapplication to calculate the intersection point of a
line and a circle. The line is defined by a point and a direction. The circle is
defined by the center point and the radius.
Distance-
Distance
Use the distance-distance subapplication to calculate the intersection point of
two circles. The circles are defined by the known point as the center point and
the distance from the known point to the COGO point as the radius.
