 == ICircleSegment vs. ICircle ==

 What if we change the proposal to derive FdoICircleSegment directly from FdoICurveAbstract, in the process renaming FdoICircleSegment to be FdoICircle.  To me, this has some merit, since as currently described, a circle must be closed and cannot be combined with any other !ArcSegment Types to form complex curve strings. They can only stand alone, and wrapping it in a !CurveString seems wasteful. If a user wished to define a non-closed circle, they would use ICircularArcSegment.

 The FdoICircle may be something of a hard sell. In OGC, Circle extends Arc, which extends !ArcString, which extends !CurveSegment, which implements !GenericCurve.

 == Can ICircularArcSegment Describe a Closed Circle ==
 
-Question:
+=== Question: ===
 
 I’m not sure how !CircularArcSegment can describe a full circle. If the start and end points are identical, then you only have two points (start/end and mid-point), which does not define the plane of the arc for XYZ dimensionality.

 For the rest of this explanation, it’s assumed that the circle is complete (start and end are same position).
