Remarks

Represents a curve segment that uses circular arc interpolation. Two main cases are supported by the three-point definition: - three distinct, non-collinear points (start, end, midpt somewhere in the curve) define an open arc - start and end coincide exactly, midpt is diametrically opposite, defining a circle (closed arc), presumed to be counterclockwise in direction when viewed from above (even if the circle isn't flat) - tilted circle: support midpt's Z ordinate not being the same as start/end, circle is tilted; the diameter that is perpendicular to the start-mid vector is parallel to XY plane. It is possible to define a vertical circle, but one must assume the direction of the normal (which will be somewhere in the XY plane). That is, one cannot define an arbitrary vertical circle using three points.
