Conversion of the complete geometry of a shape (all 3D analytical representation of surfaces and curves) into NURBS geometry (execpt for Planes). For example, all curves supporting edges of the basis shape are converted into BSpline curves, and all surfaces supporting its faces are converted into BSpline surfaces. More...

Public Member Functions  
BRepBuilderAPI_NurbsConvert ()  
Constructs a framework for converting the geometry of a shape into NURBS geometry. Use the function Perform to define the shape to convert. More...  
BRepBuilderAPI_NurbsConvert (const TopoDS_Shape &S, const Standard_Boolean Copy=Standard_False)  
Builds a new shape by converting the geometry of the shape S into NURBS geometry. Specifically, all curves supporting edges of S are converted into BSpline curves, and all surfaces supporting its faces are converted into BSpline surfaces. Use the function Shape to access the new shape. Note: the constructed framework can be reused to convert other shapes. You specify these with the function Perform. More...  
void  Perform (const TopoDS_Shape &S, const Standard_Boolean Copy=Standard_False) 
Builds a new shape by converting the geometry of the shape S into NURBS geometry. Specifically, all curves supporting edges of S are converted into BSpline curves, and all surfaces supporting its faces are converted into BSpline surfaces. Use the function Shape to access the new shape. Note: this framework can be reused to convert other shapes: you specify them by calling the function Perform again. More...

BRepBuilderAPI_NurbsConvert::BRepBuilderAPI_NurbsConvert  (  ) 
Constructs a framework for converting the geometry of a shape into NURBS geometry. Use the function Perform to define the shape to convert.
BRepBuilderAPI_NurbsConvert::BRepBuilderAPI_NurbsConvert  (  const TopoDS_Shape &  S, 
const Standard_Boolean  Copy = Standard_False 

) 
Builds a new shape by converting the geometry of the shape S into NURBS geometry. Specifically, all curves supporting edges of S are converted into BSpline curves, and all surfaces supporting its faces are converted into BSpline surfaces. Use the function Shape to access the new shape. Note: the constructed framework can be reused to convert other shapes. You specify these with the function Perform.

virtual 
Returns the list of shapes modified from the shape .
Reimplemented from BRepBuilderAPI_ModifyShape.

virtual 
Returns the modified shape corresponding to . S can correspond to the entire initial shape or to its subshape. Exceptions Standard_NoSuchObject if S is not the initial shape or a subshape of the initial shape to which the transformation has been applied.
