To the User:

This document describes Rebis's PXF file format to enable users and third party developers to read and

write AutoPLANT® piping models. The package contains field descriptions and sample model files.

PXF files are currently used for clash detection purposes and to transfer models between CAD and Stress

Analysis programs. We also see this as a tool to feed mainframe plant design systems, such as PASCE,

PDMS, and Intergraph PDS using low cost AutoCAD workstations.

Rebis seeks your comments on this specification, and will work with you to add or modify field

descriptions.

GENERAL DESCRIPTION

The PXF file format is intended to facilitate the passage of non graphic information between project applications

which must share information to perform design tasks.

The PXF is complimentary to AutoCAD's DXF exchange file. No attempt is made in the PXF to duplicate the

graphical data contained in the DXF. The ability exist to link the two graphical items in the DXF with the

associated non-graphical PXF data through the "AutoCAD handles" and "database links" (see Code fields 2006,

2007 below). This format allows each exchange file to operate in either an independent or dependent manner.

Certain applications may only require non-graphical data from a project CAD model:

eg: Pipe stress analysis

Structural Analysis

For applications of this type, the DXF file need not be created and the PXF is sufficient.

The DXF file format has already become the default format for exchange of purely graphical data between different

CAD programs:

eg: AutoCAD to Intergraph

PASCE to AutoCAD

A third class of applications require a transfer of both graphical and non-graphical data. This requirement typically

stems from the need to access and share the inherent intelligence stored in the CAD model created by multiple

distinct applications:

Project eXchange Format - Rev 3.17 3

eg: Pipe routing on a structural steel frame

HVAC routing within a structural frame

To handle the diverse intelligence of multiple application, each record of the PXF file format is comprised of two

fields:

Code field Key field (five character numeric) which identifies the type of information which

follows.

Value field Contains the assigned value in the appropriate syntax for this field.

This structure allows easy extension for expanded needs as well as easy screening and interpretation. The PXF

format also does not require that the components in the file be in any particular order. For piping components this

means that components will not necessarily be placed in pipeline order. The pipeline order can be determined by the

node numbers (3007 records).

The PXF file is an ASCII file that is no longer than 132 characters wide.

Changes in Revision 3.0

This document include changes required to facilitate the new database structure of AutoPLANT 97. In addition,

various documents describing different versions of the PXF file are consolidated. All previous versions are

superceded. The document is based on PXF definition revision dated 6/22/92, which is implemented in

AutoPLANT DESIGNER Version 11, 11.5, 12 and 13. Steel subsection is based on the PXF Definition, Steel

Member Sub-document, Revision 2.3, dated Feb. 22, 1996.

A new item code for class names is added to be consistent with classes used in the AutoPLANT 97. A new section

(Domain 5000) is added for nozzles and equipment.

Definition of Tee component and Y strainers has also changed. See Tee in APPLICATION OF PXF STRUCTURE

TO AUTOPLANT PIPING ITEMS.


Equipment module domain (5000) added. Includes information on equipment and nozzles.


Codes for Sort code (2065), Spec Tag (2066) and Spec Table (2067) added. Also corrected description of code

3029.


Code for Material Grade (MAT_GRADE, 2068) added.



Added codes for project preferences.


Added code for Project Name (1011). Also, modified 1001 code for Drawing units. Instead of numeric values now

string value of “Imperial”, “Metric” or “Mmetric” is being written to 1001 code.

For Engineering analysis result domain (8000 - 8999) refer to AutoPIPE online help for information on 8000 field

codes (search for "pxf displacement", "pxf support" or "pxf stresses") or refer to AutoPIPE SDS document:

PXF_ResultsExport_d637.DOC or D637_4.DOC.


CODE DEFINITIONS

Item codes have been grouped into domains to allow easy extension without conflict. Each domain is defined by a

specified four character range as shown below:

Domain Range Description

1 1000 - 1999 General drawing information

2 2000 - 2999 Piping component information

3 3000 - 3999 Coordinate information

4 4000 - 4999 Structural component information

5 5000 - 5999 Equipment and nozzle information

Future Extensions

The following are proposed extensions of the domains to handle other project related applications. A

reassignment of ranges may be done based on feedback from associated developers and users.

Domain Range Description

6 6000 - 6999 HVAC information

7 7000 - 7999 P&ID information

8 8000 - 8999 Engineering analysis result information.

The next four sections define the existing domains 1, 2, 3 and 4. Following this definition is a section which defines

how Rebis' piping application AutoPLANT 97 uses these domain codes to "export" and "import" PXF files of piping

components. Included in this section is a sample model and the associated PXF file created from a PXF export.

The syntax for each "value" field is expressed in parentheses following the description. If an inherent limitation

exists in the size of this field it will be stated. Note: All coordinates are expressed in the applicable units:

eg: Imperial: inches

Mixed Metric: nominal size = inches; coordinates = millimeters

Metric: millimeters

Domain 3: Point Related Data

Piping Components

The coordinate data for piping is defined as following. Primary connection points, such as the faces of a flanged

valve, are stored in 3000 records. Data that is associated with a primary connection point (also called a “port”) are

stored on record numbers 3000-3019. Reference points, such as the tangent intersection point for elbows, are stored

in 3040 records with any additional data stored in 3040-3059. Additional data can be attached to any component.

The attached data often has coordinate data which connects it to the primary item. These attachment point is stored

in 3060 records. If an attachment needs additional coordinates they are stored in 3080 records.

Each component will have a 3000 record for each point, a 3020 record for each tap, etc. When reading down the

PXF file, all 3000, 3020, 3040, etc. records are grouped by 2000 records. That is all records following a 2000 record

are for that component until another 2000 record occurs. The number of 3000 and 3040 records for a given type of

component will be fixed but the number of 3020, 3060 and 3080 will vary. If there is both structural steel and

piping in a PXF file, they can be distinguished using the 2000 record to define a piping component and a 4000

record to define a steel member.

All coordinates are real numbers with no fixed number of decimal places and are space delimited. The order is

always X Y Z where X is East, Y is North and Z is up.


3000 First connection port or point coordinates

3001 End type at point specified in field 3000 field (character).

Obsolete, retained for compatibility with old version - Use 3008 & 3009 instead.

necessarily contiguous, nor start at 1.

Structural Steel Components

The method used to store coordinate information is different for Structural Steel components than it is for piping. If

there is both structural steel and piping in a PXF file, they can be distinguished using the 2000 record to define a

piping component and a 4000 record to define a steel member. There is only one 3000 record allowed for each steel

member. To define more than one point for a member, add 20 to the codes listed below to get the corresponding

record number for the second point. For internal points, the 3040 records are used. There can be multiple 3040

records for a given component.
