class TrsfModification from BRepTools inherits Modification from BRepTools
---Purpose: Describes a modification that uses a gp_Trsf to
-- change the geometry of a shape. All functions return
-- true and transform the geometry of the shape.

Create (T : Trsf from gp) returns mutable TrsfModification from BRepTools;

---Purpose: Provides access to the gp_Trsf associated with this
-- modification. The transformation can be changed.

NewSurface(me: mutable; F : Face from TopoDS;
S : out Surface from Geom;
L : out Location from TopLoc;
Tol : out Real from Standard;
RevWires : out Boolean from Standard;
RevFace : out Boolean from Standard)
---Purpose: Returns true if the face F has been modified.
-- If the face has been modified:
-- - S is the new geometry of the face,
-- - L is its new location, and
-- - Tol is the new tolerance.
-- RevWires is set to true when the modification
-- reverses the normal of the surface (the wires have to be reversed).
-- RevFace is set to true if the orientation of the
-- modified face changes in the shells which contain it.
-- For this class, RevFace returns true if the gp_Trsf
-- associated with this modification is negative.

NewCurve(me: mutable; E : Edge from TopoDS;
C : out Curve from Geom;
L : out Location from TopLoc;
Tol: out Real from Standard)
returns Boolean from Standard
;
---Purpose: Returns true if the edge E has been modified.
-- If the edge has been modified:
-- - C is the new geometric support of the edge,
-- - L is the new location, and
-- - Tol is the new tolerance.
-- If the edge has not been modified, this function
-- returns false, and the values of C, L and Tol are not significant.
NewPoint(me: mutable; V : Vertex from TopoDS;
P : out Pnt from gp;
Tol: out Real from Standard)
returns Boolean from Standard
;
---Purpose: Returns true if the vertex V has been modified.
-- If the vertex has been modified:
-- - P is the new geometry of the vertex, and
-- - Tol is the new tolerance.
-- If the vertex has not been modified this function
-- returns false, and the values of P and Tol are not significant.

F : Face from TopoDS;
NewE : Edge from TopoDS;
NewF : Face from TopoDS;
C : out Curve from Geom2d;
Tol : out Real from Standard)
returns Boolean from Standard
;
---Purpose: Returns true if the edge E has a new curve on surface on the face F.
-- If a new curve exists:
-- - C is the new geometric support of the edge,
-- - L is the new location, and
-- - Tol the new tolerance.
-- If no new curve exists, this function returns false, and
-- the values of C, L and Tol are not significant.
NewParameter(me: mutable; V : Vertex from TopoDS;
E : Edge from TopoDS;
P : out Real from Standard;
Tol: out Real from Standard)
returns Boolean from Standard
;
---Purpose: Returns true if the Vertex V has a new parameter on the edge E.
-- If a new parameter exists:
-- - P is the parameter, and
-- - Tol is the new tolerance.
-- If no new parameter exists, this function returns false,
-- and the values of P and Tol are not significant.
Continuity(me: mutable; E : Edge from TopoDS;
F1,F2 : Face from TopoDS;
NewE : Edge from TopoDS;
NewF1,NewF2: Face from TopoDS)
returns Shape from GeomAbs
---Purpose: Returns the continuity of <NewE> between <NewF1>
-- and <NewF2>.
--
-- <NewE> is the new edge created from <E>. <NewF1>
-- (resp. <NewF2>) is the new face created from <F1>
-- (resp. <F2>).
