What do you all do for profiles themselves? That's the one file I keep together. We label all our utilities in it then xref them into "cut" sheets.
I've always had a hard time with Profiles (as in Profile Views) - mostly due to pipe networks.
I get compartmentalization, so it makes sense to design the pipe networks in a separate drawing, and DREF them where you need.
Problem is you layout the 'water main' pipe network in a drawing named UP01 (Utility Plan). You DREF that pipe network into your 'base' (plan) drawing, because you need to XREF that in other sheets where it should show up, if not for design purposes. You also DREF that pipe network into your profile (profile view) drawing, because you at minimum need label it for your sheet.
You now have duplicate DREFs, both of which are synced at drawing open... Yes, you can NOT DREF it into the 'base' drawing, but then you cannot use it for design purposes, AND you're now required to DREF it into each-and-every-single sheet drawing, which means you cannot Edit it in plan, or profile.
To that end, it doesn't make sense to have the pipe network in its own drawing, when you could instead just do the plan and profile layout within the profile drawing itself, and DREF as needed. There, you now have the ability to properly design the utility in a single drawing, that is used directly in the plan sheets via XREF.
Now, I only label the pipe network in Profile View (to be XREFed), and with the XREF in the sheet drawing, I can then label the XREF pipe network as needed.
Drefs.. for some data, and or the actual data like profiles/pipes are in the 'sheet' files and dref'ed back to the design...IF I was following correctly.
The prospect of designing a single pipe network across multiple sheet drawings, is terrifying.
Never mind the inherent requirement to match pipe elevations with each adjacent sheet, but to DREF that back into the design, just means that each sheet drawing now has both the actual pipe network, and every other pipe network to sync, utterly defeating the purpose of designing the pipe network (segment?) in the sheet from the outset, no?
... Or do you cut up the 'design' (or base?) into each sheet as well?
