Synopsis

PDX_MSGT picr_Shell(long option, int model, MDA_PTR orig_db_ptr, int tag, int identifier, MDA_COUNT n_faces, MDA_PTR *faces, int *orients, MDA_PTR acorn, MDA_COUNT n_edges, MDA_PTR *edges, int sign, int shell_type, MDA_PTR *shell_ptr)

Purpose

Create the PINT model Shell entity.

Description

This function creates a PINT Shell entity for the given input data. The data provided must result in a valid definition. 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

PICR_VALIDATE

Validate the entity fields

PICR_NOVALIDATE

Do not validate the entity fields

model

PINT model for entity creation

identifier

Parasolid's identifier

orig_db_ptr

The original entities orig_db_ptr as obtained from the mda_GetOrigDbptr call, or MDA_NULL_PTR

tag

orients

list of orientation flags for faces

acorn

MDA_PTR to vertex entity, if shell_type == PINT_SHELL_ACORN

n_edges

number of edges in the shell

edges

MDA_PTR to edge entities

sign

PINT_SHELL_POSITIVE

The volume of the shell is a finite region

PINT_SHELL_NEGATIVE

The volume of the shell is an infinite region

PINT_SHELL_OPEN
