class SolidOfRevolution from IGESSolid inherits IGESEntity
---Purpose: defines SolidOfRevolution, Type <162> Form Number <0,1>
-- in package IGESSolid
-- This entity is defined by revolving the area determined
-- by a planar curve about a specified axis through a given
-- fraction of full rotation.
uses
Pnt from gp,
Dir from gp,
XYZ from gp
is
Create returns mutable SolidOfRevolution;
-- Specific Methods pertaining to the class
Init (me : mutable;
aCurve : IGESEntity;
aFract : Real;
aAxisPnt : XYZ;
aDirection : XYZ);
---Purpose : This method is used to set the fields of the class
-- SolidOfRevolution
-- - aCurve : the curve entity that is to be revolved
-- - aFract : the fraction of full rotation (default 1.0)
-- - aAxisPnt : the point on the axis
-- - aDirection : the direction of the axis
SetClosedToAxis (me : mutable; mode : Boolean);
---Purpose : Sets the Curve to be by default, Closed to Axis (Form 0)
-- if <mode> is True, Closed to Itself (Form 1) else
IsClosedToAxis (me) returns Boolean;
---Purpose : Returns True if Form Number = 0
-- if Form no is 0, then the curve is closed to axis
-- if 1, the curve is closed to itself.
Curve (me) returns IGESEntity;
---Purpose : returns the curve entity that is to be revolved
Fraction (me) returns Real;
---Purpose : returns the fraction of full rotation that the curve is to
-- be rotated
AxisPoint (me) returns Pnt;
---Purpose : returns the point on the axis
TransformedAxisPoint (me) returns Pnt;
---Purpose : returns the point on the axis after applying Trans.Matrix
Axis (me) returns Dir;
---Purpose : returns the direction of the axis
TransformedAxis (me) returns Dir;
---Purpose : returns the direction of the axis after applying
-- TransformationMatrix
fields

-- Class : IGESSolid_SolidOfRevolution
--
-- Purpose : Declaration of variables specific to the definition
-- of the Class SolidOfRevolution.
--
-- Reminder : A SolidOfRevolution instance is defined by :
-- the curve(Curve) rotated for a fraction (Fraction) of full
-- rotation about an axis that is given by a point(X1,Y1,Z1) on
-- the axis and the direction(I1,J1,K1)
--
theCurve : IGESEntity;
-- the curve that is to be rotated
theFraction : Real;
-- the fraction of full rotation
theAxisPoint : XYZ;
-- the coordinates of the point on the axis
theAxis : XYZ;
-- the axis of rotation
end SolidOfRevolution;
