# Synopsis

PDX_MSGT gdx_DiscontToContNurbSurf(long option, T_GDX_NURB_SURF *surf)

# Purpose

Force a discontinuous Nurb surface to be continuous.

# Description

This routine forces a discontinuous GDX NURB Surface to be continuous. It averages the two points along a row or column of discontinuity to obtain the resulting continuous surface. It assumes that no interior knot has multiplicity greater than order.

# Input

## option

Not used.

## surf

Pointer to the GDX NURB Surface which is to be made continuous.

# Output

## surf

Structure pointer does not change, but knots and control points do change.

# Return

          GDX_NOERR
          Low level error return
