Revit Links as Underlays

From Autodesk Wikihelp for Revit 2012.

Using a Revit link as an underlay can be a common workflow for architects and especially for engineers. A link can be set to Halftone to distinguish it from the main model, but new work (model lines, for example) can still end up being obscured by geometry (walls, etc) in the link--making it difficult to see what you've drawn. Revit 2012 solves this problem:
  • Open your Revit project.
  • In the Insert tab, click Link Revit.
  • Navigate to the Revit model you would like to use as an underlay. Click Open.
  • In the View tab, click Visibility/Graphics (or type the keyboard shortcut “VG”).
  • Click the Revit Links tab.
  • Next to the Revit link that you just inserted, put a check in the Underlay checkbox. Click OK.
  • The geometry in the link will now be halftone, and more importantly, it's a true underlay: the link geometry will not obscure new lines and edges

I have the following comment on this new setting:

Cool but, keep in mind that this does not address the selection order experience we have unfortunately. I'm describing the situation that a linked file is "selected" by the pre-highlighting before native RST or RME elements. This means that Revit "sees" the Architecture model before it sees the RME user's duct (assuming the view is assigned to Hidden Line).

Ideally a link should take a "selection back seat" to elements that are native to the active project file.
