I reported about the problems with Revit Structure not installing and missing content back on the 15th April - What can best be called a work-a-round from Autodesk was to suggest that UK users install the USA Metric Library and harvest what was missing see my post on the 17th may about Loading Missing Content
This process does not provide everything, below is a review guide of what you should get and what’s missing once you have downloaded the USA Metric and created what should have been installed in the first place.
The structure below has been based upon :-
What installed in UK RST2012
What installed as a US Metric Library
