When troubleshooting, the ISOGEN message file FINAL.MES found in folder \PISOGEN\PROJECTS\APIPEPROJ\FINAL\OUTPUT\ provides increased message reporting using Option Switch 55=9 (Default = 1) for additional clues such as disconnections.55 9 !

Refer to the PDF files option switches.pdf, pcf component guide.pdf, in this folder. Note: Many of the switches are set automatically from the StressISO options and ISOGEN options dialogs in AutoPIPE. See the AutoPIPE online help topics ISOGEN Options General, ISOGEN Options OverFlow, ISOGEN Options Dimensioning/Text and Stress Isometric Options Plot. Please contact Bentley for additional information on customizing ISOGEN.</p> <p>9</p> <p>Rev 5.0</p> <p>Section C: Troubleshooting</p> <p>A.8.1.</p> <p>How can I systematically find the cause of ISOGEN errors?First, what is the error?</p> <p>ISOGEN will usually tell the error code in the ISOGEN progress dialog. Sometimes, a limited amount of information is given. Here are some examples of the types of messages you might receive when ISOGEN did not process the components correctly. a. ISOGEN errors: 0 Components exported. b. ISOGEN FAILED c. ISOGEN Iso: C:\Bentley Plant Project\PROJECT1\CONFIG\ISOGEN\FINAL\DRAWINGS\L100-1.PASS.DXF d. ISOGEN ERROR -13 Errors A and B are generic. Error C indicates there is a disconnect in the original AutoPLANT model. See question A.1 for details. Error D can be determined from the following PDF file: ..\PLANT 2004\AUTOISOGEN\ISOUTILS\PERSONAL ISOGEN ERROR CODES.PDF. But further investigation is usually required. In most other circumstances, the error information can be found in the following file \PISOGEN\PROJECTS\APIPEPROJ\FINAL\OUTPUT\FINAL&gt;MES) The component(s) causing the error will have *** to the right of the component. Please see the example below (an excerpt of the FINAL.MES): PIPE END-POINT 44.004 84.000 END-POINT 0.000 84.000 SUPPORT CO-ORDS 0.000 84.000 SKEY 01IN SUPPORT-DIRECTION WEST MESSAGE-SQUARE TEXT (A10 1) SUPPORT CO-ORDS 0.000 84.000 SKEY 01AN SUPPORT-DIRECTION UP</p> <p>0.000 0.000 0.000</p> <p>8.000 8.000 8.000</p> <p>***</p> <p>0.000</p> <p>8.000</p> <p>10</p> <p>Rev 5.0</p> <p>Troubleshooting MESSAGE-SQUARE By finding the corrupted component using the specified coordinates in the affected model and replacing or correcting it, ISOGEN will usually successfully run. 2. Where and when does the problem occur?</p> <p>Evaluate the sub-questions. a. Within the current model, does the problem happen on more than one pipeline segment? b. Does the problem happen on sections of that segment if components are manually selected for running StressISO? c. Does the problem happen in more than one model? As you will notice from the above questions, the problem can be narrowed down quickly and different avenues of trouble shooting can be pursued. Lets discuss each of these in depth. Questions A and B are related to each other based on whether or not ISOGEN is running at all. Most ISOGEN issues are model specific. In other words, the components in the model have been created or connected in such a way that the PCF file is generated but not recognized as valid by ISOGEN. Thus, the following questions will determine if that is the case. Can we get StressISO to run successfully in the model? If at some point it does work correctly, then the affected components can be narrowed down by using manual selection for ISOGEN processing. Hint: Run sections of the model to see which parts work and which ones don't. It's usually possible to narrow down the problem just by trial and error. Run one section. If it works, then try another. If that one fails, then run a smaller part of that section. Keep doing this until the problem is narrowed down to a few components. Sometimes an IDFGEN error or PASS_DXF file can be caused by an invalid component. By replacing this component, ISOGEN can run successfully. If ISOGEN doesnt run at all on any pipelines or ranges of pipelines, then please contact Bentley Support. c. Does the problem happen in more than one model? If the answer is no, the cause of the problem is within this model and further trouble shooting is recommended. Here are several suggestions which typically resolve ISOGEN errors. Repair possible disconnects by refering to question A.1 11 Rev 5.0</p> <p>Section C: Troubleshooting</p> <p>Contact Bentley Support if the ISOGEN issue cannot be resolved.</p> <p>A.9.</p> <p>What format can I create my custom drawing border?</p> <p>ISOGEN Drawing Borders It is recommended to create the custom border file in Autocad R12 DXF or R2000 DWG formats and use a fixed spaced (e.g. monospaced) font for the text. The default borders can be modified which contain all the colors and fonts for table data and plot text as well as symbols, pipeline etc. It is recommended to start with the default border which has all the colors assigned to all the pipe, dimensioning, text, fitting and support layers etc already defined, then modify these layers if required. Delete the default border elements then copy/paste the custom border into the drawing and save.</p> <p>A.10.</p> <p>How can I change the color and size of the Pipeline plotted?</p> <p>ISOGEN DDF File Modify the THE DRAWING-DEFINITION FILE as shown below and change the color for the pipe, pipe1, pipe2 layers in the border drawing file then re-generate the stress isometric.

In other words, after opening the bend dialog at A01 and pressing OK without making any changes, results in a round-off error in the DZ offset, i.e. 4.67 ft compared to the actual value of -4.666667 ft. This round-off error can be significant when calculating the coordinates of the bend tangent points.</p> <p>Bend Midpoint</p> <p>13</p> <p>Rev 5.0</p> <p>Section C: Troubleshooting</p> <p>Changing from 2 to 3 significant digits shows small DZ offset = 0.003</p> <p>14</p> <p>Rev 5.0</p> <p>Troubleshooting</p> <p>Stress Isometric</p> <p>15</p> <p>Rev 5.0</p> <p>Section C: Troubleshooting Workaround Set Tools/model options/Edit &gt; Digits after decimal for coordinates = 3</p> <p>Edit offset to -4.667 , with Apply offset = unchecked</p> <p>16</p> <p>Rev 5.0</p> <p>Troubleshooting</p> <p>A.13.</p> <p>Why are the flanges drawn incorrectly on the flanged valve?</p> <p>Flange is shown in the wrong orientation with respect to the valve</p> <p>17</p> <p>Rev 5.0</p> <p>Section C: Troubleshooting Workaround The Valve has been defined incorrectly as a Butt-weld instead of a flanged valve. ISOGEN can only plot a flanged valve correctly with correction pipe flange orientation if the valve is a flange type i.e. the Joint End type must be Weld-neck or Slip-on</p> <p>18</p> <p>Rev 5.0</p> <p>Troubleshooting</p> <p>A.14. One table data record is missing if it continues in the next drawingIf tables in an isometric cannot be fitted in one drawing then some tables are shifted to the next drawing sheet. However, this causes one record to be lost from the data table which continues onto the next sheet. The lost record may be the last record in the current drawing or it may be the first record in the next drawing, e.g. if FLANGE table contains 11 records, out of which 5 are to display in the current drawing and the remaining 6 are to display in the next drawing sheet, then the 6th record will be lost resulting in the display of 5 flange records in the current drawing and 5 flange records in the next drawing. This problem exists with any table which continues in the next drawing sheet and is an know ISOGEN defect to be fixed in October 2006 timeframe.</p> <p>1 record missing in the data table</p> <p>19</p> <p>Rev 5.0</p> <p>Section C: Troubleshooting</p> <p>Workaround 1. Use a small table font size to fit all the table data onto one sheet. 2. Use Selected Range and generate an isometric with table data to fit on one sheet. Note: Enhancement logged to generate a isometric using either a user-defined PCF or STS or both for AutoPIPE XM SR2. This will allow the user to edit the STS or PCF files then manually generate the stress isometric.</p> <p>A.15. Can ISOGEN create isometrics with continuous dimensioning?ISOGEN Limitation Currently ISOGEN can create isometrics with continuous string dimensioning as shown below but supports are not included in this dimensioning format. The dimensioning below can be achieved by first setting the dimensioning options similar to the dialog below then editing the APIPE.OPL file to set OPL Switch 9 = 100 and OPL Switch 40 = 10 as below: 9 40 100 10 ! Type of Dimensions on isometric ! Pipe Support information control 20 Rev 5.0</p> <p>Troubleshooting</p> <p>21</p> <p>Rev 5.0</p> <p>Section C: Troubleshooting</p> <p>A.16. Can StressISO options be saved for use of engineering team?</p> <p>Yes all Stress Isometric options are saved to stressiso.ini file and ISOGEN options are saved to apipe.opl. Both these files can copied to other workstations to achieve same isometric settings e.g. default border drawing size, dimensioning, overflow etc. Note: The stressiso.ini file does store the absolute path to the apipe.opl and border files which may vary from machine to machine depending if Autopipe has been installed to different folders on different machines. Note: If the user changes any of the stressISO or ISOGEN options before generating the stress isometric these will be updated to the stressiso.ini and apipe.opl files which will be different to the original settings.</p> <p>A.17. Is it possible to only print data associated with the isometric plot sheet shown? Currently some of the data for the 1st iso drawing overflows to the next drawing sheet.Yes this would be useful but currently ISOGEN does not have smart logic to know beforehand which drawing sheet has which table data associated with it. The overflow of Table data is only continuous and not synchronised with the plot. Workaround One workaround is to select small desired ranges or hide segments and generate ISO's with "use select range" option which will only print data on the isometric for the selected range.
