Blake, Thanks for your quick response!
Of course we will do the mapping in the manner specified by those requesting the data. However I do find that validating data where the buildings share nodes is a little more difficult. For example, if one of the two buildings is not squared (in the data), when you do square it, then the other building is likely to become out of square... The same type of thing applies if one of the buildings needs to be rotated a little to better match the imagery.
