distributed at more or less equal arc distances around the circle.
When more than 3 points are targeted, a best-fit algorithm will be
used to create the circle feature and an F (Form) value will be
included in the circle feature data.
Angle
Angles can be measured by targeting between 2 and 100 points
on each of the vertices of the angle. Generally, accuracy of the
feature is increased as more points are targeted and the targeted
points are distributed at more or less equal distances along the
line.
