class MakeCirc2d from gce inherits Root from gce
---Purpose : This class implements the following algorithms used
-- to create Circ2d from gp.
--
-- * Create a Circ2d concentric with another and passing
-- though a point.
-- * Create a Circ2d concentric with another at the distance
-- Dist.
-- * Create a Circ2d passing through 3 points.
-- * Create a Circ2d with its center and radius.
-- * Create a Circ2d with its center and a point given
-- the radius.
-- * Create a Circ2d with its axis and its radius.

Create (XAxis : Ax2d from gp ;
Radius : Real from Standard ;
Sense : Boolean from Standard = Standard_True) returns MakeCirc2d;
--- Purpose :
-- The location point of XAxis is the center of the circle.
-- Warnings :
-- It is not forbidden to create a circle with Radius = 0.0
-- If Sense is true the local coordinate system of the solution
-- is direct and non direct in the other case.
-- The status is "NegativeRadius" if Radius < 0.0.
Create (Axis : Ax22d from gp ;
Radius : Real from Standard) returns MakeCirc2d;
--- Purpose :
-- The location point of Axis is the center of the circle.
-- Warnings :
-- It is not forbidden to create a circle with Radius = 0.0
Create(Circ : Circ2d from gp ;
Dist : Real from Standard)
returns MakeCirc2d;
---Purpose : Makes a Circ2d from gp <TheCirc> concentric with another
-- circ2d <Circ> with a distance <Dist>.
-- If Dist is greater than zero the result encloses
-- the circle <Circ>, else the result is enclosed by the
-- circle <Circ>.
-- The local coordinate system of the solution is the
-- same as Circ.
Create(Circ : Circ2d from gp;
Point : Pnt2d from gp)
returns MakeCirc2d;
---Purpose : Makes a Circ2d from gp <TheCirc> concentric with another
-- circ2d <Circ> and passing through a Pnt2d <Point>.
-- The local coordinate system of the solution is the
-- same as Circ.
Create(P1 : Pnt2d from gp;
P2 : Pnt2d from gp;
P3 : Pnt2d from gp)
returns MakeCirc2d;
---Purpose : Makes a Circ2d from gp <TheCirc> passing through 3
-- Pnt2d <P1>,<P2>,<P3>.
-- The local coordinate system of the solution is given
-- by the three points P1, P2, P3.
Create(Center : Pnt2d from gp ;
Radius : Real from Standard ;
Sense : Boolean from Standard = Standard_True)
returns MakeCirc2d;
---Purpose : Makes a Circ2d from gp <TheCirc> with its center
-- <Center> and its radius <Radius>.
-- If Sense is true the local coordinate system of
-- the solution is direct and non direct in the other case.
Create(Center : Pnt2d from gp ;
Point : Pnt2d from gp ;
Sense : Boolean from Standard = Standard_True)
returns MakeCirc2d;
---Purpose : Makes a Circ2d from gp <TheCirc> with its center
-- <Center> and a point giving the radius.
-- If Sense is true the local coordinate system of
-- the solution is direct and non direct in the other case.
