Point_Curves are NURBS
curve objects defined by interpolated points. All NURBS objects are
created through the special NURBS descriptor classes (see
Working with
NURBS) and the Point_Curve
class is used typically in object class testing with the
**classOf()**
function. Scene objects
created as Point Curve shape objects in the **3ds
Max** user interface have the
class **Point_Curve**.

**Constructor**

**NURBSNode**
<nurbs_set>
...

See Creating New NURBS Objects for details.

**Properties**

<Point_Curve>.**angle**
Float
default: 0.0 -- animatable

The rotational position of the cross-section in the renderer.

<Point_Curve>.**thickness**
Float
default: 1.0 -- animatable

Diameter of the rendered curve.

<Point_Curve>.**sides**
Float
default: 12.0 -- animatable

Sets the number of sides for the curve mesh in the renderer. A value of 4 will give you a square cross section, for example.

<Point_Curve>.**renderable** Boolean
default: true

When on, the curve is displayed in the rendered scene.

<Point_Curve>.**mapCoords** Boolean
default: false

Turn this on to apply mapping coordinates. The U coordinate wraps once around the thickness of the NURBS curve; the V coordinate is mapped once along the length of the curve.

Additional properties for point curves are accessed through a NURBSSet descriptor object. See Working with NURBS for more details.
