# Synopsis

PDX_MSGT gdx_FaceDeleteParmCurves(long option, MDA_PTR gdx_face_ptr)

# Purpose

Delete Parameter Space curves in a Face.

# Description

Delete all parameter space curves in the face. Also, degenerate model space edges will be removed from the loops. After parm curves are removed, there is no way to generate parm curves at the poles for the degenerate model curves.

# Input

## option

### GDX_KEEP_POLE_CAPS

Keep the cap loops. Basically, non-degenerate parm curves of degenerate model curve.

### GDX_KEEP_DEGEN_LOOPS

Keep all degenerate loops.

## gdx_face_ptr

The database pointer for the GDX face entity

# Output

## gdx_face_ptr

An updated GDX solid with parameter space curves

# Tolerances

          .fi

# Return

          GDX_NOERR
          GDX_INVALIDMODEL
          Low level error return
