OPIM is crashing due to four (4) Stop Signs reasonably close together. The Stop Signs are being used to separate spools enabling each spool of which there are several, to be on a separate sheets.
The position of the stop signs has not changed for the last 3 months, and I have successfully run Isometrics with OPIM on the same pipeline. The only change to the problematic spool is that two (2) welds have changed from Shop Welds to Field Fit Welds today with 50mm additional length added (enabled option in the Schema).
I had a similar problem last December 2015, but the latest version seemed to fix the problem until now. I really need the ability to place Stop Signs at practical positions normally at the Face of Flanges. If that is not possible, then placing Stop Signs to break up Iso's into practical Spools is useless.
In the screenshot below you can see the Stop Signs in green (I changed the colour to make them more visible). The Spool is basically an "H" shape for fabrication, so I really need the Stop Signs where they are now placed.
You can see below that where the first purple Isometric appears is where OPIM crashes. Line Number FG-51050-50-CA2B is the Spool in the image above that is causing the crash.
Anyone have any ideas?
Apologies, Line Number should read FG-51050-50-CA2B_6

Hi Abhijit,
I have attached an image showing location of FFW, in blue rectangles. Stop Signs are in green just for visibility.
Okay. This morning I tried a different approach trying to isolate what may be causing the OPIM to crash, or more accurately fail to generate an Isometric.
In the screenshot below I have indicated which is the Top and Bottom circuits. FFW's and Stop Signs indicated have been removed but need to be there for Iso generation
What I have established is that there is nothing wrong with the actual piping model as the Iso generates normally when Stop Signs are removed.
Troubling thing is that the same piping circuit was generating properly prior to some changes to the Regulating valves size. Now it just will not generate an Isometric(s).
Something I should have mentioned earlier is that when placing a Stop Sign it doesn't always select the face of the flange (which is where it needs to be in my case), but more often than not it selects the weldneck (at the weld in my case). Now, using the T to toggle the placement should do the trick, but no. Sure it places the Stop Sign at the face of the flange, but when I generate an Isometric the flange gets placed on a sheet all on its own and not on the same sheet as the piping spool..
1. Place Stop Sign selects the weldneck.
2. Use T to toggle placement.
3. Generated Isometric with Flange from above on its own sheet.
Hello Stephen,
Regarding isometric crash issue. could you please try following steps:
1. Go Project Administrator.
2. Select your current project.
3. Open isometric configuration Manager.
4. Click on Isometric Management Tab.
5. Max. ISO continuing components set value to 1.
6. Save the settings.
7. Generate isometric to review the result.
Hope this helps. Looking forward to your reply.
Regards,
Abhijit Bute

Abhijit, you are a marvel. Changing -1 to 1 did the trick. Thank you.
I have generated a complete set of Isometrics for two different pipelines from two different models without error or crash.
Wish this had been covered in the OPIM training course, but I suppose you can't possibly cover everything or every situation.
The only outstanding item to be fixed now is the lone flange on its own Iso sheet due to the Stop Sign placement issue I mentioned previously in this thread.
As per below (see previous item in this thread):
