# Synopsis

PDX_MSGT picr_Edge(long option, int model, MDA_PTR orig_db_ptr, int tag, int identifier, MDA_PTR start_vertex, MDA_PTR end_vertex, MDA_PTR curve, int curve_orient, MDA_COUNT n_fins, MDA_PTR *fins, int vertex_type, int enclosure_type, int fin_type, double precision, MDA_PTR *edge_ptr)

# Purpose

Create the PINT model Edge entity.

# Description

This function creates a PINT Edge 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

Parasolid tag for this entity

## start_vertex

MDA_PTR to start vertex entity

## end_vertex

MDA_PTR to start vertex entity

## curve

MDA_PTR to curve entity

## curve_orient

orientation of the curve

## n_fins

### 0

, May be zero, but need to have memory for fins (2).

## fins

list of MDA_PTRs to region entities

## vertex_type

### PINT_EDGE_OPEN

The edge has two distinct vertices

### PINT_EDGE_CLOSED

The start and end vertex are coincedent

### PINT_EDGE_RING

The edge has no vertices

## enclosure_type

### PINT_EDGE_INSIDE

The edge is surrounded by solid regions

### PINT_EDGE_OUTSIDE

The edge is surrounded by void regions

### PINT_EDGE_ON

The edge is adjaicent to both solid and void regions

## fin_type

### PINT_EDGE_WIREFRAME

The edge is a wireframe (no fins)

### PINT_EDGE_LAMINAR

The edge has one fin

### PINT_EDGE_NORMAL

The edge has two fins, with opposite senses

### PINT_EDGE_GENERAL

The edge has some other combination of fins

## precision

Precision of edge

# Output

## edge_ptr

The PINT model pointer

# Return

          Low level error return
