# Synopsis

PDX_MSGT igdx_502ToVertexList(long option, MDA_PTR db_ptr, int model, GDX_MATRIX *gdx_matrix, MDA_COUNT *num_of_vertices, MDA_PTR **gdx_vertex_list)

# Purpose

Create the GDX form of the IGES vertex entities

# Description

Creates the GDX form of the IGES vertex entities as the list of GDX vertex entities in the GDX model. The IGES vertex entities must be valid IGES definitions.

# Input

## option

The entity creation option (Not used)

## db_ptr

The IGES 502 entity database pointer

## model

The GDX vertex entity model for creation

## gdx_matrix

The GDX matrix to apply to the geometry or NULL

# Output

## num_of_vertices

The count of vertices in the vertex list

## gdx_vertex_list

The pointer to the list of the GDX form of the vertex entity database pointer. Note: The application must free the vertex list after used.
