Standard_Boolean | AdjustCurve (const Handle< Geom_Curve > &C3D, const gp_Pnt &P1, const gp_Pnt &P2, const Standard_Boolean take1=Standard_True, const Standard_Boolean take2=Standard_True) const |
Modifies a curve in order to make its bounds confused with given points. Works only on lines and B-Splines, returns True in this case, else returns False. For line considers both bounding points, for B-Splines only specified. More... | |

Handle< Geom_BSplineCurve > | ConvertToBSpline (const Handle< Geom_Curve > &C, const Standard_Real first, const Standard_Real last, const Standard_Real prec) const |
Converts a curve of any type (only part from first to last) to bspline. The method of conversion depends on the type of original curve: BSpline -> C.Segment(first,last) Bezier and Line -> GeomConvert::CurveToBSplineCurve(C).Segment(first,last) Conic and Other -> Approx_Curve3d(C[first,last],prec,C1,9,1000) More... | |

Modifies a curve in order to make its bounds confused with given points. Works only on lines and B-Splines, returns True in this case, else returns False. For line considers both bounding points, for B-Splines only specified.
Warning : Does not check if curve should be reversed

) | const |
Modifies a curve in order to make its bounds confused with given points. Works only on lines and B-Splines.
For lines works as previous method, B-Splines are segmented at the given values and then are adjusted to the points.
