Detailed Description

• defining the construction of the arc of circle,
  
• implementing the construction algorithm, and
  
• consulting the results. In particular, the
  Value function returns the constructed arc of circle.

• the sense determined by the order of the points P1, P3 and P2;
  
• the sense defined by the vector V; or
  
• for other syntaxes:
  
  • the sense of Circ if Sense is true, or
    
  • the opposite sense if Sense is false.
    Note: Alpha1, Alpha2 and Alpha are angle values, given in radians.
    Warning
    If an error occurs (that is, when IsDone returns
    false), the Status function returns:
    
• gce_ConfusedPoints if:
  
  • any 2 of the 3 points P1, P2 and P3 are coincident, or
    
  • P1 and P2 are coincident; or
    
• gce_IntersectionError if:
  
  • P1, P2 and P3 are collinear and not coincident, or
    
  • the vector defined by the points P1 and
    P2 is collinear with the vector V.
