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. |

41 | ---Purpose: Constructs a framework for converting the geometry of a |
42 | -- shape into NURBS geometry. Use the function Perform |

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 |
56 | -- function Perform. |
