Measuring a circle
Circles can be measured by targeting between 3 and 100 points
around the circumference. Generally, accuracy of the feature is
increased as more points are targeted and the targeted points are
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.
