class ConeFrustum from IGESSolid inherits IGESEntity
---Purpose: defines ConeFrustum, Type <156> Form Number <0>
-- in package IGESSolid
-- The Cone Frustum is defined by the center of the
-- larger circular face of the frustum, its radius, a unit
-- vector in the axis direction, a height in this direction
-- and a second circular face with radius which is lesser
-- than the first face.

---Purpose : This method is used to set the fields of the class
-- ConeFrustum
-- - Ht : the Height of cone
-- - R1 : Radius of the larger face
-- - R2 : Radius of the smaller face (default 0)
-- - Center : Center of the larger face (default (0,0,0))
-- - anAxis : Unit vector in axis direction (default (0,0,1))
Height (me) returns Real;
---Purpose : returns the height of the cone frustum
LargerRadius (me) returns Real;
---Purpose : returns the radius of the larger face of the cone frustum
SmallerRadius (me) returns Real;
---Purpose : returns the radius of the second face of the cone frustum
FaceCenter (me) returns Pnt;
---Purpose : returns the center of the larger face of the cone frustum
TransformedFaceCenter (me) returns Pnt;
---Purpose : returns the center of the larger face of the cone frustum
-- after applying TransformationMatrix
Axis (me) returns Dir;
---Purpose : returns the direction of the axis of the cone frustum
TransformedAxis (me) returns Dir;
---Purpose : returns the direction of the axis of the cone frustum

-- Reminder : A ConeFrustum instance is defined by :
-- The Cone Frustum is defined by the center of the
-- larger circular face of the frustum(X1,Y1,Z1), its radius(R1),
-- a unit vector in the axis direction(I1,J1,K1),a height in this
-- direction(Height) and a second circular face with radius(R2)
-- R1 > R2

-- the radius of the larger face of the cone frustum
theR2 : Real;
-- the radius of the smaller face of the cone frustum
theFaceCenter : XYZ;
-- the larger face center coordinates
theAxis : XYZ;
-- the Unit vector in axis direction
