# Synopsis

PDX_MSGT gdx_LoopSealGaps(long option, MDA_PTR gdx_loop_ptr, MDA_PTR gdx_surf_ptr, double ms_gap_tol)

# Purpose

Closes gaps between edge curves in a Loop

# Description

This functions closes the gap between two consecutive edge curves in a loop. If the edge parm curve has been modified to fix the gap then the all edge model curve and the vertices associated with the gap are deleted and regenerated.

# Input

## option

### GDX_MODEL_ONLY

Check for gaps between model curves only

### GDX_PARM_ONLY

Check for gaps between model curves only. If a gap is found between parm curves fix the parm curves only and not the model curves

### GDX_MODEL_PARM_BOTH

Check for gaps in model and parm curves and modify both to fix the gap

## gdx_loop_ptr

Database pointer of GDX Loop.

## gdx_surf_ptr

Database pointer of surface the loop is on.

## ms_gap_tol

The model space gap tolerance.

# Output

## gdx_loop_ptr

Database pointer of Modified GDX Loop.

# Return

          Low level error return
