◆ Continuity()

virtual GeomAbs_Shape BRepTools_Modification::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 
)
pure virtual

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>).

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

◆ NewCurve()

virtual Standard_Boolean BRepTools_Modification::NewCurve ( const TopoDS_Edge E,
Handle< Geom_Curve > &  C,
TopLoc_Location L,
Standard_Real Tol 
)
pure virtual

Returns true if the edge, E, has been modified. If the edge has been modified:

  • 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, BRepOffset_SimpleOffset, ShapeCustom_ConvertToBSpline, BRepTools_TrsfModification, BRepTools_GTrsfModification, BRepTools_NurbsConvertModification, ShapeCustom_ConvertToRevolution, ShapeCustom_DirectModification, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.

◆ NewCurve2d()

virtual Standard_Boolean BRepTools_Modification::NewCurve2d ( const TopoDS_Edge E,
const TopoDS_Face F,
const TopoDS_Edge NewE,
const TopoDS_Face NewF,
Handle< Geom2d_Curve > &  C,
Standard_Real Tol 
)
pure virtual

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 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, BRepOffset_SimpleOffset, ShapeCustom_ConvertToBSpline, ShapeCustom_BSplineRestriction, BRepTools_TrsfModification, BRepTools_GTrsfModification, BRepTools_NurbsConvertModification, ShapeCustom_ConvertToRevolution, ShapeCustom_DirectModification, ShapeCustom_SweptToElementary, and ShapeCustom_TrsfModification.

◆ NewParameter()

virtual Standard_Boolean BRepTools_Modification::NewParameter ( const TopoDS_Vertex V,
const TopoDS_Edge E,
Standard_Real P,
Standard_Real Tol 
)
pure virtual

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

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

◆ NewPoint()

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

Returns true if the vertex V has been modified. If V 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.

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

◆ NewPolygon()

virtual Standard_Boolean BRepTools_Modification::NewPolygon ( const TopoDS_Edge E,
Handle< Poly_Polygon3D > &  P 
)
virtual

Returns true if the edge has been modified according to changed polygon. If the edge has been modified:

  • P is a new polygon

◆ NewPolygonOnTriangulation()

virtual Standard_Boolean BRepTools_Modification::NewPolygonOnTriangulation ( const TopoDS_Edge E,
const TopoDS_Face F,
Handle< Poly_PolygonOnTriangulation > &  P 
)
virtual

Returns true if the edge has been modified according to changed polygon on triangulation. If the edge has been modified:

  • P is a new polygon on triangulation

◆ NewSurface()

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

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. 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, ShapeCustom_ConvertToBSpline, BRepTools_TrsfModification, BRepOffset_SimpleOffset, BRepTools_GTrsfModification, BRepTools_NurbsConvertModification, ShapeCustom_ConvertToRevolution, ShapeCustom_DirectModification, ShapeCustom_TrsfModification, and ShapeCustom_SweptToElementary.

◆ NewTriangulation()

virtual Standard_Boolean BRepTools_Modification::NewTriangulation ( const TopoDS_Face F,
Handle< Poly_Triangulation > &  T

Returns true if the face has been modified according to changed triangulation. If the face has been modified:

  • T is a new triangulation on the face
