# Synopsis

PDX_MSGT gdx_SolidSurfImproveNurbParams(long option, MDA_PTR gdx_solid_ptr, int *mod_flag)

# Purpose

Improve the NURBS parameters of the surface in each face of solid.

# Description

This function will improve the parameter uniformness of the surfaces that are nurbs based. If the surface is improved, existing parameter space curves on the faces will be deleted. For more specific information refer to gdx_FaceSurfImproveNurbParams.

# Input

## option

Options (not used)

## gdx_solid_ptr

DB pointer of GDX Solid with surfaces to be improved

# Output

## mod_flag

Flag indicating whether or not surface knots and bounds were modified: = 0 : No modificated faces. = 1 : Modified faces.

# Return

          GDX_NOERR
          GDX_MODEL_LOOP_NOT_CONT
          Low level error return
