# Synopsis

PDX_MSGT gcr_Shell2(long option, MDA_PTR orig_db_ptr, MDA_COUNT num_of_faces, PDX_BOOL senses[], MDA_PTR face_ptrs[], int gdx_model, MDA_PTR *gdx_shell_ptr)

# Purpose

Create a GDX Shell.

# Description

Given the number of faces, the sense for each face, and the pointers to the faces create a GDX Shell. The sense flags indicates the senses of the faces with respect to the shell, PDX_TRUE means the sense agrees.

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
