Vector Normal to a Surface

Synopsis

SNORF(obj,u,v)

Description

Returns the components of a vector normal to the surface at a position specified by the U and V scalars. All Unigraphics surfaces are valid for SNORF. Detailed explanations of how the U and V values apply to the various surfaces, are given in the SPOSF function.

Parameters

Parameter

Description

obj

An existing surface which is used to calculate the normal vector.

u,v

Scalar values which can be any Unigraphics real number which define the location of the normal vector calculation in U and V parameter space. The scalar values located on the surface are from 0 to 1. Any value beyond that range lies on the extensions of the surface.
