Dealing with Priorities with mixed Files

Question

I have several MicroStation sheet files that contain both MicroStation and AutoCAD reference drawings. I am running into issues when I try to control what displays on top of what, on an elemental level. I can't grab one file and push it to the back or bring it to the front since there are some items in each file that need to be controlled individually. What is the best and most consistent way to deal with this? Should I try to have all my reference files in 3D and control what goes where with elevations? I'm not sure what the best way forward would be. 
 Thanks!

You should not have any issues changing level priorities, By-level or override settings in nested reference files. Make sure you have the variable set MS_LEVEL_EDIT_NESTED_ATTACHMENT_LEVELS. This is under Workspace/Configuration you want to have this set to 1. This turns this variable on. In your level manager you should be able to select the level you want and make the change you desire.

If your files are 3D - then yes , elevation is what controls what is seen on top of what. If the files are 2D, then priorities can be used. These can be set on elements, levels or files (references).

If you are in a 3D model use elevations to make the adjustments and in 2D you should use priorities. You can also use Update Sequence in the Reference manager to move the Reference files up and down in display order this may also help. This is under located under the settings pull down. In two file you can also use Bring to Front under the Edit pull down.
