class MakeCylinder from gce inherits Root from gce
---Purpose : This class implements the following algorithms used
-- to create a Cylinder from gp.
-- * Create a Cylinder coaxial to another and passing
-- through a point.
-- * Create a Cylinder coaxial to another at a distance
-- <Dist>.
-- * Create a Cylinder with 3 points.
-- * Create a Cylinder by its axis and radius.
-- * Create a cylinder by its circular base.

Create (A2 : Ax2 from gp ;
Radius : Real from Standard) returns MakeCylinder;
--- Purpose :<A2> is the local cartesian coordinate system of <me>.
-- The status is "NegativeRadius" if R < 0.0
Create(Cyl : Cylinder from gp;
Point : Pnt from gp) returns MakeCylinder;
---Purpose : Makes a Cylinder from gp <TheCylinder> coaxial to another
-- Cylinder <Cylinder> and passing through a Pnt <Point>.
Create(Cyl : Cylinder from gp ;
Dist : Real from Standard) returns MakeCylinder;
---Purpose : Makes a Cylinder from gp <TheCylinder> coaxial to another
-- Cylinder <Cylinder> at the distance <Dist> which can
-- be greater or lower than zero.
-- The radius of the result is the absolute value of the
-- radius of <Cyl> plus <Dist>
Create(P1 : Pnt from gp;
P2 : Pnt from gp;
P3 : Pnt from gp) returns MakeCylinder;
---Purpose : Makes a Cylinder from gp <TheCylinder> with 3 points
-- <P1>,<P2>,<P3>.
-- Its axis is <P1P2> and its radius is the distance
-- between <P3> and <P1P2>
Create(Axis : Ax1 from gp ;
Radius : Real from Standard) returns MakeCylinder;
---Purpose: Makes a Cylinder by its axis <Axis> and radius <Radius>.
Create(Circ : Circ from gp) returns MakeCylinder;
---Purpose: Makes a Cylinder by its circular base.
-- Warning
-- If an error occurs (that is, when IsDone returns
-- false), the Status function returns:
-- - gce_NegativeRadius if:
-- - Radius is less than 0.0, or
-- - Dist is negative and has an absolute value
-- which is greater than the radius of Cyl; or
-- - gce_ConfusedPoints if points P1 and P2 are coincident.
Value(me) returns Cylinder from gp
raises NotDone
is static;
---C++: return const&
---Purpose: Returns the constructed cylinder.
-- Exceptions StdFail_NotDone if no cylinder is constructed.
Operator(me) returns Cylinder from gp
is static;
---C++: return const&
---C++: alias "Standard_EXPORT operator gp_Cylinder() const;"

--The solution from gp.
