/** \details
  The vertical circular arc segment is defined as an arc using the inherited attributes from IfcAlignment2DVerticalSegment 
  and the following additional curve parameters Radius as the radius of the circular arc, 
  and IsConvex to indicate the whether the circular arc defines a sag (i.e. concave, increasing gradient) or a crest (i.e. convex, decreasing gradient).
  The circular arc is described by:
  * x = offset as length measure relative to start of curve segment (i.e. 0 is at head).
  * g<sub>1</sub> = StartGradient as ratio measure
  * R = Radius as length measure
  
  For crest curves (where IsConvex is True), the elevation of a point along the curve (relative to StartHeight) is defined as:
  
  <IMAGE ifcalignment2dversegcirculararc-formula-concave>
  
  For sag curves (where IsConvex is False), the elevation of a point along the curve (relative to StartHeight) is defined as:
  
  <IMAGE ifcalignment2dversegcirculararc-formula-convex>
  
  Example of alignment vertical arc segment convex:
  
  <IMAGE ifcalignment2dversegcirculararc-convex>
