# Synopsis

PDX_MSGT gcr_CompEdgeCurve(long option, MDA_PTR orig_db_ptr, MDA_COUNT num_edge_curves, struct t_gdx_comp_edge_curve_surf_curves *surf_curves, int gdx_model, MDA_PTR *gdx_CEC_ptr)

# Purpose

Create a GDX Composite Edge Curve.

# Description

This function creates a GDX Composite Edge Curve entity for the given structures of edge curves and sense flags. The edge curves are assumed valid (possibly created by calling gcr_EdgeCurve).

The GDX Composite Edge Curve's closed field is set using tolerance of GDX MODEL_SPACE_POINT_COIN_TOL.

The orig_db_ptr argument should contain the database pointer of the entity that the new entity was created from (usually this should be obtained by the calling routine via mda_GetOrigDbptr) or MDA_NULL_PTR. See the mda_intro man page for more information about predecessor entities.

# Input

## option

### GCR_NOVALIDATE

No validation will occur on the input data.

## orig_db_ptr

The original entity's database pointer as obtained from mda_GetOrigDbptr, or MDA_NULL_PTR.

## num_edge_curves

The number of edge curves

## surf_curves

MDA memory containing the structures of sense flags and database poiters of Edge curves. Always consumed by this function even on error.

## gdx_model

The GDX model for entity creation.

# Output

## gdx_CEC_ptr

Entity database pointer of the GDX Composite Edge Curve.

# Return

          GCR_NOERR
          GCR_BAD_GDX_MODEL
