# Synopsis

PDX_MSGT gdx_FaceSurfImproveNurbParams(long option, MDA_PTR gdx_face_ptr, int *mod_flag)

# Purpose

Improve the NURBS parameters of the surface in this face.

# Description

This function will improve the parameter uniformness of the surface of the face if it is nurbs based. If the surface is improved, existing parameter space curves will be deleted. For more specific information refer to gdx_SurfaceImproveNurbParams.

# Input

## option

Options (not used)

## gdx_face_ptr

DB pointer of GDX Face with surface to be improved

# Output

## mod_flag

Flag indicating whether or not surface knots and bounds were modified: = 0 : Nothing modified. = 1 : u-knots modified. = 2 : v-knots modified. = 3 : both u-knots and v-knots were modified, and possibly the corresponding bounds.

# Return

          GDX_NOERR
          GDX_MODEL_LOOP_NOT_CONT
          Low level error return
