Currently I have one pipeline (one line number) on which I have placed several "Stop Signs" on at logical spool breaks, normally at a flanged connection to split the pipe over several sheets making it easier for our workshop to read and follow. Each "Stop Sign" designates the start point and end point of a logical spool. In a nutshell each designated spool is on a separate sheet. So for example, Spool A is on Sheet 1, Spool B on Sheet 2, etc........and so on.
Although it works quite well, OPIM does some crazy things from time to time. Such as, putting the discharge end on sheet 1 and the inlet (supply end) on the last sheet.
I have 13 sheets in total.
What I require is to be ability to control which end of the pipeline is placed on sheet 1. Normally I would expect Iso's to start on sheet 1 from the Inlet end in the direction of flow. Completing on the last sheet, being the Outlet end.
Is this possible? And if not, why not?
Hi Steve,
Have you tried reversing the flow arrow and generating sheets? For multiple Pipeline having different situation, where user expects one line with start point & another with End point as sheet 1, in that case what would user do?
I am trying to take out number of cases where I should be able to discuss it further.
You may expect responses from experts here.

The image below is the pipeline in question, showing the flow arrows and Stop Signs (in Green). Placing the Stop Signs where indicated should produce 10 Iso sheets, as there are 9 logical spools with 2 of them spilt for clarity.
The Inlet is shown in the Yellow Box, and the Outlet is shown in the Light Blue Box. I would reasonably expect that OPIM would start the Iso generation at the Inlet as First Sheet, and the Outlet as the last sheet in the series. So, if there are 10 sheets the Inlet Spool would be on Sheet 1, and the Outlet spool on Sheet 9.
However, OPIM is generating them the other way around, with the Outlet Spool as the First Sheet, and the Inlet Spool as the Last sheet. Even though you can clearly see where the starting Flow Arrow is placed on the Inlet pipe after the flange.
Also, the Stop Signs are not working as expected, as OPIM is generating 13 sheets not 10, splitting Spools at Flange welds and in arbitrary places at Tess.........This all causing me great frustration.
My expectations of OPIM are that it will honour wherever I place the Stop Signs, but this is not the case. I far more sophisticated method of controlling this behaviour would be preferable.
