10. Iso Output Node:Path
Select the Iso Output Node:Path field and key in the nodename:path where the ISOGEN output files will be stored. The default is set to nodename:/login directory.
The key-in fields: Iso Output Node:Path, Iso Options File and Iso Seed Design File will accept a network address.
Each should be entered as nodename:drive:\directory path\filenamefor example:
111jn:C:\win32app\ingr\dat\defaults.dat.
To change the default settings for the Iso Output Node:Path field, edit the ISOPATH export statement.
Edit the pds.cmd file located in ˜\pdiso\bin. For example, a typical ISOPATH export statement in the pds.cmd file might be:
$ENV{’ISOPATH’}=’PDSNT:C:\users\iso\isofiles\\’;
11. Iso Design File
Select the Iso Design File field and key in the ISOGEN design file. By default, the first pipeline name is displayed with a .iso extension.
The .iso extension will generate multi-sheet isometrics into a single design file. Replacing the .iso extension with a .i* extension allows the software to generate multi-sheet isometrics into separate design files where the * will be replaced with a number.
For example, if the model in the Interactive Isometric Extraction form was changed to 400104wc.i*, the resulting design files would be
400104wc.i01, 400104wc.i02,, etc. This procedure will allow you to take advantage of ISOGEN’s plotting capabilities as described in the section Plot Isometric Drawing.
The the most recently processed iso, displayed in the Iso Design File, becomes the first selection on the list of available isos when the Plot or View Graphics command is selected.
12. Iso Options File
Select the Iso Options File field and key in the nodename:path where the ISOGEN options file is located.
If you key in an options filename and the file does not exist, an error message is displayed at the bottom of the form.
The options file contains switches, options and tables that drive the Intergraph interface to ISOGEN. This file allows you to customize iso’s to your standard practice.
The default is set to nodename:/pathname. The default value is delivered in the options file and can be altered by exporting the ISOOPTION variable.
13. Iso Seed Design File
Select the Iso Seed Design File field and key in the nodename:path where the ISOGEN seed design file is located.
If you key in a seed filename and the file does not exist then an error message is displayed at the bottom of the form.
The iso seed design file is a 2-D design file that is copied to create an empty design file into which the isometric is drawn by ISOGEN.
The default is set to nodename:/path name/iso seed file. The default value is determined when the ISOSEED export variable is defined.
To change the default settings for the Iso Options File and Iso Seed Design File fields, edit the ISOSEED and ISOOPTION export statements in the PDS.CMD file.
The following are examples of typical ISOSEED and ISOOPTION export statements as they would appear in the defaults.dat file.
export ISOSEED=$ENV{’ISOSEED’} = ’pdssrv:D:\proj\iso\ref\isoc.sed’
export ISOOPTION=$ENV{’ISOOPTION’} = ’pdssrv:D:\proj\iso\ref\isoc.def’

3.1 Extraction Criteria
The following sections contain information specific to defining extraction criteria which must be defined prior to initializing an isometric extraction. The following extraction criteria are covered in this section:
Model Files Pipeline Names
– Generation by Line Name Substring – Generation by Line ID
Iso Design File
__________________________________________________________________________________________________________________________________________________
3.1.1 Model Files
Key in the names of the PDS Piping, Equipment Modeling and/or Pipe Support files that should be considered for iso extraction. Up to eight model numbers can be input. Equipment model numbers must be specified in order to generate nozzles on the isometric.
The first model number entered is treated as the primary file and therefore must be a Piping model. Any RDB data accessed during iso extraction is obtained from the primary model (through its type 63 data).
The RDB data that is accessed by the Iso Extraction Software and that must be properly attached to the primary file includes:
Specification Material Database Graphic Commodity Library Physical Dimension Library Piping Job Spec Tables Library Standard Notes Library
Material Descriptions Library
Specialty and Instrument Descriptions Library Label Description Library
Miscellaneous data stored within the model itself
If the model number that you specify does not exist, the software displays an error message at the bottom of the form. Press <RETURN> to proceed.
If the model number is invalid, the software displays the message Error Retrieving Model and the fully expanded filename is displayed in the input field.
A filename is considered invalid if it does not exist in the project database.
__________________________________________________________________________________________________________________________________________________
3.1.2 Pipeline Names
Key in the pipe lines that are to be extracted into a single iso. Up to 8 lines can be specified.
The lines you specify must be connected together in the Piping Model files. That is, these pipelines must be a network of piping segments. In order for the lines to be connected, the segments that form those lines must also be connected. You cannot specify multiple disconnected piping sections (such as, vessel trim piping).
Pipelines can be identified for extraction in two ways: extraction by line name substring and extraction by line id (see the section Conventions and Limitations). The method you use depends upon the options selected and set in the iso extraction options file. Refer to The Options File, page 7 - 1 for more information.
For each method, you identify the network of piping to extract by specifying piping segment attributes. Piping segments usually correspond only to sections of piping and NOT to an entire piping system (unless the line is trivial).
