PointNormal

 
 
 

The smoothed normal at locations on a geometry.

If you get this attribute at locations on a NURBS surface or curve, the values are calculated directly from the NURBS equations instead of being interpolated from surrounding points.

If you get this attribute on a NURBS surface or curve by an explicit string reference, for example Get Data ("curve.PointNormal"), the context is per point and the values represent the values of the NURBS hull (control polyline) at the control points (CVs) rather than values on the curve or surface itself.
