## Nurbs class

The NURBS.
Describes a NURBS curve in 3D space.



**Inheritance:** [`Nurbs`](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs) → 
[`ColladaElement`](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/colladaelement)



The Nurbs type exposes the following members:

### Constructors
| Constructor | Description |
| :- | :- |
| [__init__](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs/__init__/#) | Initializes a new instance of the [`Nurbs`](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs) class. |


### Properties
| Property | Description |
| :- | :- |
| [source](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs/source) | Gets or sets the source. |
| [control_vertices](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs/control_vertices) | Gets or sets the control vertices.
<br/>The control vertices element  must occur  exactly one time.
<br/>It is used to describe the CVs of the spline. |
| [extra](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs/extra) | Gets or sets the extra. |
| [degree](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs/degree) | Gets or sets the degree.
<br/>Specifies the degree of the NURBS curve. |
| [closed](/cad/python-net/aspose.cad.fileformats.collada.fileparser.elements/nurbs/closed) | Gets or sets a value indicating whether curve is closed.
<br/>Specifies whether a NURBS curve is closed.
<br/>The default is false.
<br/>Optional. |
