P&ID Line List not showing all lines

[AarTomas]

Hello, I appear to be having a bit of a problem with making P3D models from P&IDs. When I try to add lines from the P&ID line list some pages show their lines whilst other pages do not. Both of these pages in the picture below are "completed" P&IDs.

Any ideas how to fix the pages so that the lines show up?

I'm thinking it might be buried somewhere within the Page Options. I've been told the drawings were all made the same way as well.

Any thoughts or directions would be much appreciated, as we have to start this 3d modeling buisness fairly shortly.

Thanks!

The Line List dialog box evidently sees the completed drawing, so it is odd it’s not listing anything. Even if it were all untagged lines, you should still get a list of question marks. First thing to make sure of is that all applicable Service Packs or Hot Fixes have been applied to your version of Plant 3D. Also try an Audit on the P&ID drawing and then try doing a thorough Audit Project, as in…close all drawings, verify no one else in project, Audit Project, restart Plant 3D, open same project and do Audit Project again, first thing.  Then check to see if  that Line List shows up now.

The Audit thing did the trick!

Thank you sir! You saved me from unecessarily updating the .XML of this project from default, which would've taken me forever! (And used up my day off)

Much thanks!

Awesome tip; this saved me a ton of work. So Audit the file, save the file, then close it. Then reopen the file and run the Auditproject command, and it should be repaired.
