Level Display on multiple sheets

Rikke:

It would appear that the settings for the sheets and referenced drawings are as per the Sheet Seed.dgnlib which is used to create them. I venture a guess that if you go to your dgnlib sheet seed and make "universal" changes to it (them), the settings will propagate as new sheets are created. The notion is analogous to any seed file; that is, when creating a new model from seed, the seed's settings are propagated to the new model.

I don't know how OpenRoads sets up the sheets, but in the past, I have gotten around this by creating a "collector" drawing which references all my design files. I control level display (among other things) from here, using Global Display. That Collector is referenced into each sheet with Live Nesting to a depth = 1 and "Display Overrides" set to Never.

It's still possible for sheets to get out of sync, but it certainly makes a good starting point.
Also, take a look at the design file setting REFLEVELOVERRIDES. This should probably be set to ON. This is analogous to the AutoCAD setting VISRETAIN. If it is OFF, it will not save any reference level display changes. Drove me NUTS until I found out about it. You can look it up in the Help file for more information.

If OpenRoads will not use a collector by default, you may be able to go through each sheet and repath your design file to the collector. You'd still have to open each sheet, but you may be able to get away with only doing it once.

Centralizing and controlling level display for large numbers of sheets has been a bugaboo for us for years. We haven't got it all figured out (because there's always something...) but this approach has worked best for us so far.
