class Modification from Draft inherits Modification from BRepTools
---Purpose:
uses Shape from TopoDS,
Face from TopoDS,
Edge from TopoDS,
Vertex from TopoDS,
Location from TopLoc,
ListOfShape from TopTools,
IndexedDataMapOfShapeListOfShape from TopTools,
Orientation from TopAbs,
Shape from GeomAbs,
Surface from Geom,
Curve from Geom,
Curve from Geom2d,
Pnt from gp,
Lin from gp,
Pln from gp,
Dir from gp,
ErrorStatus from Draft,

raises NotDone from StdFail,

is
Create(S: Shape from TopoDS)
returns mutable Modification from Draft;
Clear(me: mutable)
---Purpose: Resets on the same shape.
is static;
Init(me: mutable; S: Shape from TopoDS)
---Purpose: Changes the basis shape and resets.
is static;
Add(me: mutable; F : Face from TopoDS;
Direction : Dir from gp;
Angle : Real from Standard;
NeutralPlane: Pln from gp;
Flag : Boolean from Standard = Standard_True)
---Purpose: Adds the face F and propagates the draft
-- modification to its neighbour faces if they are
-- tangent. If an error occurs, will return False and
-- ProblematicShape will return the "bad" face.
returns Boolean from Standard
raises ConstructionError from Standard
-- The exception is raised if ProblematicShape does not
-- return a null shape
is static;
Remove(me: mutable; F: Face from TopoDS)
---Purpose: Removes the face F and the neighbour faces if they
-- are tangent. It will be necessary to call this
-- method if the method Add returns Standard_False,
-- to unset ProblematicFace.
raises NoSuchObject from Standard
-- The exception is raised if F has not been added.
is static;
Perform(me: mutable)
---Purpose: Performs the draft angle modification and sets the
-- value returned by the method IsDone. If an error
-- occurs, IsDone will return Standard_False, and an
-- error status will be given by the method Error,
-- and the shape on which the problem appeared will
-- be given by ProblematicShape
raises ConstructionError from Standard
--- The exception is raised if ProblematicShape does not
-- return a null shape.
is static;
IsDone(me)
---Purpose: Returns True if Perform has been succesfully
-- called. Otherwise more information can be obtained
-- using the methods Error() and ProblematicShape().
returns Boolean from Standard
is static;
Error(me)
returns ErrorStatus from Draft
is static;
ProblematicShape(me)
---Purpose: Returns the shape (Face, Edge or Vertex) on which
-- an error occured.
returns Shape from TopoDS
---C++: return const&
is static;
ConnectedFaces(me: mutable; F: Face from TopoDS)
returns ListOfShape from TopTools
---Purpose: Returns all the faces which have been added
-- together with the face <F>.
--
---C++: return const&
raises NoSuchObject from Standard,
-- The exception is raised if F has not been added.
NotDone from StdFail
-- The exception is raised if IsDone returns False.
is static;
ModifiedFaces(me: mutable)
returns ListOfShape from TopTools
---Purpose: Returns all the faces on which a modification has
-- been given.
--
---C++: return const&
raises NotDone from StdFail
-- The exception is raised if ProblematicShape does not return
-- a null shape.
is static;
-- Methods inherited from BRepTools_Modification
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 Standard_True if the face <F> has been
-- modified. In this case, <S> is the new geometric
-- support of the face, <L> the new location,<Tol>
-- the new tolerance.<RevWires> has to be set to
-- Standard_True when the modification reverses the
-- normal of the surface.(the wires have to be
-- reversed). <RevFace> has to be set to
-- Standard_True if the orientation of the modified
-- face changes in the shells which contain it. Here
-- it will be set to Standard_False.
--
-- Otherwise, returns Standard_False, and <S>, <L>,
-- <Tol> , <RevWires> ,<RevFace> are not significant.
returns Boolean from Standard
;
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 Standard_True if the edge <E> has been
-- modified. In this case, <C> is the new geometric
-- support of the edge, <L> the new location, <Tol>
-- the new tolerance. Otherwise, returns
-- Standard_False, and <C>, <L>, <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 Standard_True if the vertex <V> has been
-- modified. In this case, <P> is the new geometric
-- support of the vertex, <Tol> the new tolerance.
-- Otherwise, returns Standard_False, and <P>, <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 Standard_True if the edge <E> has a new
-- curve on surface on the face <F>.In this case, <C>
-- is the new geometric support of the edge, <L> the
-- new location, <Tol> the new tolerance.
--
-- Otherwise, returns Standard_False, and <C>, <L>,
-- <Tol> are not significant.
--
-- <NewE> is the new edge created from <E>. <NewF>
-- is the new face created from <F>. They may be usefull.
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 Standard_True if the Vertex <V> has a new
-- parameter on the edge <E>. In this case, <P> is
-- the parameter, <Tol> the new tolerance.
-- Otherwise, returns Standard_False, and <P>, <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>).
