I'm just starating out with revit so please bear with me. Most everyhwere I've read recommends you link a revit file using the Auto- Origin to Origin positioning, and seemingly with good reason. However; when the import window pops up it always defaults to Auto- Center to Center positioning. Is there a way to set the positioning to defaut with origin to origin?

You cannot change the default setting. It shouldn't matter terribly which you use to begin a project, so long as you 'Acquire Shared Coordinates'. I've heard arguments for both, but did not retain enough information to to be able elaborate confidently...
As the previous post stated unfortunately this is a default setting within the Revit Architecture Program and the order of the drop down list cannot be reorderd to suite your needs.

Ideally you should use origin to origin and agree between your project team (both internal and external) that all models will have the same origin points. Also these origin points will ideally be located to provide positive values to all building element co-ordinates for recti-linear buildings or in the centre of circular/ovoid buildings such as sports stadia.
This way it doesn't really matter when other models have elements outside the building envelope, affecting the central position of the model, and you don't have to mess around aligning building models to each other when people start modelling in different positions, etc. Also makes it easier for linking CAD files. Once this is set up then acquiring shared co-ordinates is a fairly straight forward matter(ish!!).
Steve,
Thanks for explination, at least we finally have ONE reason for using center to center, unfortunately just like you said the reality is that drawings are a perfect storm of chaos. Even so much as having to expand the wall thickness of an exterior wall will shift the center- rendering our MEP model completely changed. As such, it would seem the potential for this extreme drawback is too great for an end user to justify using it, even if that means sacrificing the developer's 12th decimal place of accuracy. If anything, reality ditactes you should probably be pushing to have people set the origin near the drawing elements- not throwing the origin away and hoping everything just happens to line up.
At least that just my two cents any ways.
