Standard_EXPORT | ShapeAnalysis_Edge () |
Empty constructor; initialises Status to OK . | |
Standard_EXPORT Standard_Boolean | HasCurve3d (const TopoDS_Edge &edge) const |
Tells if the edge has a 3d curve . | |

Standard_EXPORT Standard_Boolean | IsSeam (const TopoDS_Edge &edge, const Handle(Geom_Surface)&surface, const TopLoc_Location &location) const |
Returns True if the edge has two pcurves on one surface . | |
Standard_EXPORT TopoDS_Vertex | FirstVertex (const TopoDS_Edge &edge) const |
Returns start vertex of the edge (taking edge orientation into account). . | |
Standard_EXPORT TopoDS_Vertex | LastVertex (const TopoDS_Edge &edge) const |

Standard_EXPORT Standard_Boolean | CheckVerticesWithCurve3d (const TopoDS_Edge &edge, const Standard_Real preci=-1, const Standard_Integer vtx=0) |
Checks the start and/or end vertex of the edge for matching with 3d curve with the given precision. <vtx> = 1 : start vertex only <vtx> = 2 : end vertex only <vtx> = 0 : both (default) If preci < 0 the vertices are considered with their own tolerances, else with the given <preci>. . | |
