class MakeCirc from gce inherits Root from gce

    ---Purpose : This class implements the following algorithms used 
    --           to create Circ from gp.
    --           
    --           * Create a Circ coaxial to another and passing 
    --             though a point.
    --           * Create a Circ coaxial to another at the distance 
    --             Dist.
    --           * Create a Circ passing through 3 points.
    --           * Create a Circ with its center and the normal of its 
    --             plane and its radius.
    --           * Create a Circ with its center and its plane and its 
    --             radius.
    --           * Create a Circ with its axis and radius.
    --           * Create a Circ with two points giving its axis and 
    --             its radius.
    --           * Create a Circ with is Ax2 and its Radius.

Create (A2     : Ax2  from gp      ;
        Radius : Real from Standard)  returns MakeCirc;
    --- Purpose : 
    --  A2 locates the circle and gives its orientation in 3D space.
    --- Warnings :
    --  It is not forbidden to create a circle with Radius = 0.0
    --- The status is "NegativeRadius" if Radius < 0.0

Create(Circ : Circ from gp      ;
       Dist : Real   from Standard) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> coaxial to another 
    --           Circ <Circ> at a distance <Dist>.
    --           If Dist is greater than zero the result is encloses 
    --           the circle <Circ>, else the result is enclosed by the 
    --           circle <Circ>.

Create(Circ    :     Circ from gp;
       Point   :     Pnt  from gp) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> coaxial to another 
    --           Circ <Circ> and passing through a Pnt2d <Point>.

Create(P1,P2,P3 : Pnt  from gp) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> passing through 3 
    --           Pnt2d <P1>,<P2>,<P3>.

Create(Center  : Pnt  from gp      ;
       Norm    : Dir  from gp      ;
       Radius  : Real from Standard) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> with its center 
    --           <Center> and the normal of its plane <Norm> and 
    --           its radius <Radius>.

Create(Center  : Pnt  from gp      ;
       Plane   : Pln  from gp      ;
       Radius  : Real from Standard) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> with its center 
    --           <Center> and the normal of its plane <Plane> and 
    --           its radius <Radius>.

Create(Center  : Pnt  from gp      ;
       Ptaxis  : Pnt  from gp      ;
       Radius  : Real from Standard) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> with its center 
    --           <Center> and a point <Ptaxis> giving the normal 
    --           of its plane <Plane> and its radius <Radius>.

Create(Axis   : Ax1  from gp      ;
       Radius : Real from Standard) returns MakeCirc;
    ---Purpose : Makes a Circ from gp <TheCirc> with its center 
    --           <Center> and its radius <Radius>.
    -- Warning
    -- The MakeCirc class does not prevent the
    -- construction of a circle with a null radius.
    -- If an error occurs (that is, when IsDone returns
    -- false), the Status function returns:
    -- -   gce_Negative Radius if:
    --   -   Radius is less than 0.0, or
    --   -   Dist is less than 0.0 and the absolute value of
    --    Dist is greater than the radius of Circ;
    -- -   gce_IntersectionError if the points P1, P2 and
    --   P3 are collinear, and the three are not coincident;
    -- -   gce_ConfusedPoints if two of the three points
    --   P1, P2 and P3 are coincident; or
    -- -   gce_NullAxis if Center and Ptaxis are coincident.
