.TH SEDITPT

.SH NAME
SEDITPT
SurfaceType SEDITPT( SurfaceType Srf, CtlPtType CPt, NumericType UIndex,
NumericType VIndex )
Provides a simple mechanism to manually modify a single control point number
UIndex and VIndex (base count is 0) in the control mesh of Srf
by substituting CtlPt instead. CtlPt must have the same point type as
the control points of Srf. Original surface Srf is not modified.
Example:
CPt = ctlpt( E3, 1, 2, 3 );
NewSrf = SEDITPT( Srf, CPt, 0, 0 );
Constructs a NewSrf with the first control point of Srf being
CPt.
