The documentation officially says is not possible to add 2D documents to a 3D view (Web's user Manual).
I was looking for this function too.
I think the most promising way is to go through Revit, which can shows overlay plans at the right level and position, and export them alongside with IFC.
In TC should appear also in 3D and you may control visibility through layers.
At least is what's happening with DWG overlays, I have to check with PDFs.
It's not the same thing as having a managed document with all the features in place, but for sharing annotations and plans against the model may be enough.
Anyway, the competition is moving forward and I don't see any major improvement in TC in the past years...
Worse, they are pulling out some, like DWG editing, and never releasing beta features that are sitting there for years...
I'm asking myself what's the future for this product.

Not seeing this anywhere in documentation. There doesn't seem to be any way to add a PDF to a model in TC. Please provide a source or demonstration.
