Dealing with Priorities with mixed Files

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).

I suppose my issue is more related to priorities with AutoCAD files. I have been adjusting straight MS files without issue. But if I have a mix of reference files (some MS and some ACAD), how should this be handled? Let's say I have an ACAD existing file that has most of the topo drawn at elevation and then it has some property lines drawn at 0. I also have a proposed 2D microstation file that has proposed road and building improvements and also includes some patterned areas to designate proposed sod. My issue comes when I want most of the topo to be displayed at 0 priority (for the sake of a reference point), the property lines to be displayed at 100, the proposed improvements to be at 50, and the proposed pattern areas to be at -50. If I have all of that, what are my options? Should I set the MS file to 3D and adjust the elevations appropriately?

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.
