Personal ISOGEN Files Understanding Personal ISOGEN Files

Personal ISOGEN uses data from two sources to produce a piping Isometric drawing. Thedescription of the pipeline comes from the Piping Design System in a Piping Component File(PCF), and the user requirements on how that data is to be processed and presented come from aset of user definable control files.

This section describes the following Personal ISOGEN operating files.

1. Piping Component Files (PCF).

2.

The ISOGEN.FLS file.3. The Message File.

4. Options files.

5. Material List Definition files (MLD).

6. Drawing Definition File (DDF).

7. The Weld Definition File (WDF).

8. User Defined Drawing Frames.

9. Output Data files (Text files for printing or passing data to other systems).

5.2

1) Piping Component Files (PCFs)

PCFs are text files containing component and routing information. They are created by the PipingDesign System extracting information from the piping model and passing this as an input file to

Personal ISOGEN for the creation of an isometric.

A single PCF can contain the data for a number of pipelines but generally The Piping DesignSystem extracts piping data for single pipelines only and then the Personal ISOGEN system willproduces isometrics for one pipeline at a time.

At the end of each run Personal ISOGEN places a copy of the PCF it has processed in the \PISOGEN\PROJECTS\projname\PCFS directory. If the user has access to a server version of ISOGEN these PCFs may be processed as a batch for final issue and document control. Otherusers also find the PCF to be a convenient and easily understood data file describing the pipeline itrepresents, and even use it as a source of data to feed other programs. This latter use should,however, be adopted only after consultation with Alias Limited to ensure that future changes in file

format do not invalidate the proposed use.

Personal ISOGEN can not reprocess a PCF from a previous run, and the pipeline musttherefore be re-extracted from the Piping Design System if a re-run is required. This willcreate a new PCF which will overwrite any existing PCF of the same name unless it isremoved from the ...\PCFS directory before the run.

Sample PCF input

Users will not normally need to see the detail in their PCFs. However, an example PCF for theabove pipeline is shown here for information.

In the interests of brevity, only the shaded start and end sections of the pipeline are shownin the file.

3) The Message FileEvery time Personal ISOGEN runs it writes a message to a file whose name and path are specified inthe ISOGEN.FLS file. The message is appended to this file so it will grow progressively larger as

Personal ISOGEN is used. These messages are only created for diagnostic purposes and as long aseverything works normally these will be of no interest of no interest to the user.

It is therefore recommended that the file is deleted from time to time to conserve disk space.

If Personal ISOGEN runs but does not produce valid output, you should save a copy of the MessageFile together with the Piping Design System Design File, the PCF and any output files which havebeen created. These will help the Personal ISOGEN support staff diagnose the problem.

4) Options Files. Personal ISOGEN contains a large number of variable features. For example :-

1. Isometric type

2. Bill of Materials position on the isometric

3. Dimensional units

4. Isometric drawing size

5. Cut pipe list - ON/OFF

6. Line weight and symbol size

etc.

These, and other features are all controlled by settings made by the user and held in the OptionsFile. Each isotype installed for a project will in fact have its own Options File containing thesettings relevant for the particular style and content.

Each Options File contains a total of 140 switches, many of which have several positions. Mostfeatures are controlled in numeric form by a single Option Switch, but some of the more advancedfeatures need two.

Like most other Personal ISOGEN control files, the Options File is a text file that may be createdand edited with any standard text editor but to simplify the process of making changes to settings,an Options Switch Editor is provided for use with Personal ISOGEN . To change Option Switchessimply click on the Options File Editor icon in the Personal ISOGEN Utilities group and load thefile of interest. Go to the appropriate page(s) for the switches you wish to change and select thenew settings. Then save the file and you are ready to use it. If you have not been provided with theOptions Switch Editor, please ask your Piping Design system supplier or contact Alias Limiteddirectly.

5) Material List Definition file (MLD)This file is only needed if you wish to utilise the User Defined Material List (Material List is alsoknown as Bill of Material or BOM ).

The following options are available:-

1. Two further Material List styles - in addition to the standard one

2. The ability to transfer components from their standard category to another one

3. Add Remarks - taken from a user-defined file of standard Remarks

4. Specify a Material Control File with user defined content and layout

Examples of the different Material List Styles

1) Style 1 Material List

This is the standard Material List which is produced without a user defined MLD file. The contentand layout are fixed but the headings can be redefined using AText (see section 6).


With a Style 2 Material List you can customise the layout and column headings through entries inthe MLD file.

This is the MLD file that produced the Style 2 Material List above.

PT-NO 2 RN.S. 8 LITEM-CODE 15 LDESCRIPTION 28 LQTY 79

Each data item to be included in the material list is defined on a line with its internal ISOGENname, the start column for its location and the justification of the data field (Left / Right).

The user is responsible for ensuring that sufficient space is allowed in each column for thelongest likely text string.


MATER IAL LIST - FABRICATION PT.NO QTY CODE SIZE ITEM THK/RAT ENDS MATL. STANDARD REF.

With this style of Material List, the data items are plotted into pre-defined areas of the drawingframe. The data in the MLD file for this type of Material List is described in the ReferenceManual.

Style 3 Material List - Features:-

Data is plotted onto a user defined backing sheet containing all column headings and boxlines.

The user defines the X/Y data positions in the MLD file.

There are three types of layout:

Continuous (all Up or all Down). Up and Down ( e.g. FAB Up, ERECT Down).

Sectionalised, with separate sections for Fabrication Erection and Offshore items.

6) Drawing Definition File (DDF)This file is used to customise the appearance of isometrics by defining such features as :-

1. Thickness of the plotted pipeline - independently by bore

2. The thickness and scale of all fittings - flanges, olets, valves, instruments, welds, etc.

3. Round or square elbows and bends - controlled by bore range

4. Set drawing Layers for all parts of the isometric - e.g.

PIPEFITTINGSMATERIAL-LISTDIMENSION-TEXTDIMENSION-LINESFRAME

Colours can be set up for the layers in the MicroStation seed file to help in distinguishing the variousparts of the Isometric.

Example

This is the standard isometric produced without a DDF.

5.12

This is the same pipeline but the following changes have been made by the inclusion of a DDF.

1. Piping greater than 2 bore has been made thicker

2. All the fittings and welds have been scaled up in size and drawn slightly thicker

3. Elbows are depicted square instead of round

Although the drawing looks quite different it is produced from exactly the same PCF.

Full details of the allowable content of the DDF are given in the Reference Manual.

The Personal ISOGEN installation includes a default DDF for each isotype. These can becustomised as required by the user. A DDF editor is available to users of Personal ISOGEN . If you have not received a copy of this utility with your Personal ISOGEN installation, please ask the supplier of your Piping Design System or contact Alias Limited directly.

7) The Welding Definition File (WDF)Detailed Weld information may be shown on the isometric in a plotted Weld Table like the oneshown here. The table is user definable and will often contain spaces for data to be filled in laterduring fabrication or erection as well as columns for data contained within the PCF. The WeldTable (sometimes known as the Weld Box) is placed in the bottom right hand corner of the plotted


14/19


5.14

area of the drawing. Examples of Weld Tables can be seen in the samples included in the \PISOGEN\PROJECTS\TESTPROJ\SPOOL directory on installation.

To generate a plotted Weld Table on the isometric, you must supply relevant information in aWelding Definition File (WDF) which must be referenced in the ISOGEN.FLS against thekeyword WELDING-DEFINITION.

Welding Definition File data

The data in the file WELDING.WDF to produce the above Weld Table output looks like this :-

WELD-BOX-HEADINGSWELD | SIZE | WELD | WELD |No | INS | TYPE | CATEGORY |

WELD-BOX-DATA-ITEMSWELD-NO 5 R

N.S. 10 LWELD-TYPE 17 LWELD-CAT 26 L

For full details of the content of the WDF see the Reference manual.

8) User Defined Drawing FramesWhen you installed Personal ISOGEN a pre-defined drawing frame was loaded as a seed file foreach isotype . Although these can be used as required, it is most likely, at some time you will wantto make your own frames and have your isometrics plotted onto them. User Defined DrawingFrames are drawings created in the format to suit your Piping Design environment. egMicroStation Design Files (DGN) and DXF or DWG files for AutoCAD. You can thereforecustomise the frame to include information such as a company logo and other symbols and text.Also, the layouts may be designed to suit your exact requirements. These Design Files are thenused as seed files or underlays during the isometric production phase.


15/19


5.15

Actions required to modify a User Defined Drawing Frame

1. Use MicroStation or AutoCAD to modify the appropriate seed file as required.

2. Modify the associated AText file to change or suppress ISOGEN text as required. (See

section 6 for control of AText .)3. Identify the location on the drawing for any new or revised data items and modify the TextPos

file accordingly.

4. Add records to the ISOGEN.FLS to specify:

Include a record to point to the Drawing Frame file name :

DRAWING-FRAME Drawing_Frame_Name.DGN

Include a record pointing to the file that contains your TextPos data.

POSITIONED-TEXT Text_Position_Name.POS

Include a record pointing to the file that contains your AText data.

ALTERNATIVE-TEXT AText_Name.ALT

In the case of AutoCAD a DXF drawing frame can be used as an underlay into which theisometric is merged as it is created by Personal ISOGEN but this adds significantly to bothprocessing time and to the size of the drawing files created. A preferable alternative is to create thedrawing frame as a DWG file and to create the Isometrics as a DXF without a DRAWING-FRAME record in the ISOGEN.FLS. The DWG file can then be loaded into AutoCAD and theDXF imported into it for plotting or the addition of data missing from the PCF.

Please note that when working in a MicroStation environment the Design File for eachisotype must be called isotype .DGN. eg for the isotype FINAL it will be calledFINAL.DGN, and for the isotype CHECK it will be called CHECK.DGN. For othersystems you may use any valid file name as long as you specify it correctly in theISOGEN.FLS record.

Example Drawing Frame:

This is a sample User Defined Drawing Frame. As may be seen, the main area is divided intotwo - the space on the right is for the Material List and the one on the left for the addition of the isometric picture.

Along the bottom of the frame are various boxed areas with corresponding descriptive text.The appropriate data is placed in the boxes using TEXTPOS (see section 6) when theisometric produced by Personal ISOGEN is superimposed onto the drawing frame as follows.

9) Output data filesIn addition to producing isometrics, Personal ISOGEN can also output information to text files forprinting or use as data input for other systems. The types of files that may be produced in this wayinclude :-

1. Printed Material List (BOM). This may be either the standard default version oralternatively, with a user defined content and layout and may be created either in addition to orinstead of the Material List on the Iso.

2. Material Control File. With user defined content and format.

3. Weld Summary File. With user defined content and format.

Printed Material List (BOM)

1. To obtain a standard Style 1 printed Material List for a pipeline all you have to do is to

include an entry in the ISOGEN.FLS defining the name of the file to be created. egPRINTED-MATERIAL-LIST BOM.MAT

The file BOM.MAT will then be created and data will be appended to it for each pipelineprocessed by Personal ISOGEN.

2. To obtain a user defined Style 2 printed Material List you must :

a) make a PRINTED-MATERIAL-LIST filename entry in the ISOGEN.FLS file as above,

and

b) add a PRINTED-MATERIAL-LIST-TITLES section to your MLD file for the printed

page titles. The remainder of the Material List control data will be taken from STYLE2-COLUMN-HEADINGS and STYLE2-DATA-ITEMS information in the MLD file, whichmeans the printed Material List will look just like the plotted one.

If required the Material List may be suppressed such that it does not appear on thedrawing by setting Option Switch 23. (See Reference Manual.)

Material Control File

To obtain a user defined Material Control output file you must:-

a) include an entry in the ISOGEN.FLS defining the name of the file to be created. eg

MATERIAL-CONTROL MATLC.MACThe file MATLC.MAC will be created and data will be appended to it for every pipelineprocessed by Personal ISOGEN .

and

Weld Summary File

A Weld Summary File can be created either in Append mode whereby data is added to the file

each time Personal ISOGEN

is run, or in Overwrite mode whereby a new file is created eachtime.

In the case of Overwrite files the user must move or rename each file as the same namewill be used for each run.

To obtain a user defined Weld Summary file you must :-

a) include an entry in the ISOGEN.FLS defining the name and type of the file to be created.eg

WELD-SUMMARY-OVERWRITE WELDSUM.WSOor WELD-SUMMARY-APPEND WELDSUM.WSA

and

b) add a section to the Welding Definition File (WDF) to define the printed output file.
