virtual Standard_Boolean NewSurface (const TopoDS_Face &F, Handle< Geom_Surface > &S, TopLoc_Location &L, Standard_Real &Tol, Standard_Boolean &RevWires, Standard_Boolean &RevFace)=0
 Returns true if the face, F, has been modified.
If the face has been modified:

virtual Standard_Boolean NewCurve (const TopoDS_Edge &E, Handle< Geom_Curve > &C, TopLoc_Location &L, Standard_Real &Tol)=0
 Returns true if the edge, E, has been modified.
If the edge has been modified:

virtual Standard_Boolean NewPoint (const TopoDS_Vertex &V, gp_Pnt &P, Standard_Real &Tol)=0
 Returns true if the vertex V has been modified.
If V has been modified:

virtual Standard_Boolean NewCurve2d (const TopoDS_Edge &E, const TopoDS_Face &F, const TopoDS_Edge &NewE, const TopoDS_Face &NewF, Handle< Geom2d_Curve > &C, Standard_Real &Tol)=0
 Returns true if the edge, E, has a new curve on
surface on the face, F.
If a new curve exists:

virtual Standard_Boolean NewParameter (const TopoDS_Vertex &V, const TopoDS_Edge &E, Standard_Real &P, Standard_Real &Tol)=0
 Returns true if the vertex V has a new parameter on the edge E.
If a new parameter exists:

virtual GeomAbs_Shape Continuity (const TopoDS_Edge &E, const TopoDS_Face &F1, const TopoDS_Face &F2, const TopoDS_Edge &NewE, const TopoDS_Face &NewF1, const TopoDS_Face &NewF2)=0
 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>).

  • C is the new geometry associated with the edge,
  • L is its 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.

Implemented in Draft_Modification, ShapeCustom_BSplineRestriction, BRepTools_NurbsConvertModification, BRepTools_TrsfModification, BRepTools_GTrsfModification, ShapeCustom_ConvertToBSpline, ShapeCustom_DirectModification, ShapeCustom_ConvertToRevolution, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.

  • C is the new geometry of the edge,
  • L is the new location, and
  • Tol is the new tolerance.
    NewE is the new edge created from E, and NewF is
    the new face created from F.
    If there is no new curve on the face, this function
    returns false, and the values of C, L and Tol are not significant.

Implemented in Draft_Modification, ShapeCustom_BSplineRestriction, BRepTools_TrsfModification, ShapeCustom_ConvertToBSpline, BRepTools_NurbsConvertModification, BRepTools_GTrsfModification, ShapeCustom_DirectModification, ShapeCustom_ConvertToRevolution, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.

  • P is the parameter, and
  • Tol is the new tolerance.
    If there is no new parameter this function returns
    false, and the values of P and Tol are not significant.

Implemented in Draft_Modification, ShapeCustom_BSplineRestriction, BRepTools_TrsfModification, ShapeCustom_ConvertToBSpline, BRepTools_NurbsConvertModification, BRepTools_GTrsfModification, ShapeCustom_DirectModification, ShapeCustom_ConvertToRevolution, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.

virtual Standard_Boolean BRepTools_Modification::NewPoint ( const TopoDS_Vertex V,
gp_Pnt P,
Standard_Real Tol 
) [pure virtual]
  • 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.

Implemented in ShapeCustom_BSplineRestriction, Draft_Modification, BRepTools_TrsfModification, BRepTools_NurbsConvertModification, BRepTools_GTrsfModification, ShapeCustom_ConvertToBSpline, ShapeCustom_DirectModification, ShapeCustom_ConvertToRevolution, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.

virtual Standard_Boolean BRepTools_Modification::NewSurface ( const TopoDS_Face F,
Handle< Geom_Surface > &  S,
TopLoc_Location L,
Standard_Real Tol,
Standard_Boolean RevWires,
Standard_Boolean RevFace 
) [pure virtual]
  • S is the new geometry of the face,
  • L is its new location, and
  • Tol is the new tolerance.
    The flag, RevWires, is set to true when the
    modification reverses the normal of the surface, (i.e.
    the wires have to be reversed).
    The flag, RevFace, is set to true if the orientation of
    the modified face changes in the shells which contain it.
    If the face has not been modified this function returns
    false, and the values of S, L, Tol, RevWires and
    RevFace are not significant.

Implemented in Draft_Modification, ShapeCustom_BSplineRestriction, BRepTools_NurbsConvertModification, BRepTools_TrsfModification, BRepTools_GTrsfModification, ShapeCustom_ConvertToBSpline, ShapeCustom_DirectModification, ShapeCustom_ConvertToRevolution, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.
