23 class NurbsConvert from BRepBuilderAPI inherits ModifyShape from BRepBuilderAPI
25 ---Purpose: Conversion of the complete geometry of a shape into
26 -- NURBS geometry. For example, all curves supporting
27 -- edges of the basis shape are converted into BSpline
28 -- curves, and all surfaces supporting its faces are
29 -- converted into BSpline surfaces.
35 ShapeModification from BRepBuilderAPI,
36 ListOfShape from TopTools
40 Create returns NurbsConvert from BRepBuilderAPI;
41 ---Purpose: Constructs a framework for converting the geometry of a
42 -- shape into NURBS geometry. Use the function Perform
43 -- to define the shape to convert.
44 Create(S: Shape from TopoDS;
45 Copy: Boolean from Standard = Standard_False)
47 returns NurbsConvert from BRepBuilderAPI;
48 ---Purpose: Builds a new shape by converting the geometry of the
49 -- shape S into NURBS geometry. Specifically, all curves
50 -- supporting edges of S are converted into BSpline
51 -- curves, and all surfaces supporting its faces are
52 -- converted into BSpline surfaces.
53 -- Use the function Shape to access the new shape.
54 -- Note: the constructed framework can be reused to
55 -- convert other shapes. You specify these with the
58 Perform(me: in out; S : Shape from TopoDS;
59 Copy: Boolean from Standard = Standard_False)
61 ---Purpose: Builds a new shape by converting the geometry of the
62 -- shape S into NURBS geometry.
63 -- Specifically, all curves supporting edges of S are
64 -- converted into BSpline curves, and all surfaces
65 -- supporting its faces are converted into BSpline surfaces.
66 -- Use the function Shape to access the new shape.
67 -- Note: this framework can be reused to convert other
68 -- shapes: you specify them by calling the function Perform again.
