# Synopsis

PDX_MSGT gcr_RectMesh2(long option, MDA_PTR orig_db_ptr, MDA_COUNT num_u_points, MDA_COUNT num_v_points, double ***mesh_points, double ***mesh_parms, int gdx_model, MDA_PTR *gdx_rm_ptr)

# Purpose

Create a GDX Rectangular Mesh.

# Description

A GDX Rectangular Mesh entity is created for the given number of model space points. 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 entities orig_db_ptr as obtained from the mda_GetOrigDbptr call, or MDA_NULL_PTR.

## num_u_points

Number of model space points in u direction.

## num_v_points

Number of model space points in v direction.

## mesh_points

MDA memory array containing model space points [u][v][3].

## mesh_parms

MDA memory array containing parameter space points [u][v][2] or NULL.

## gdx_model

The GDX model for entity creation

# Output

## gdx_rm_ptr

Entity database pointer of the GDX Rectangular Mesh.
