The recently introduced Subscription Advantage Pack for Inventor 2010 subscription users adds a couple of new tools and functions to your Inventor 2010. These new functions will be probably included directly in Inventor 2011. Do not install the Pack on a localized version of Inventor.
Among the new functions there are e.g. chain dimensions and dimensioning styles, text islands in hatches, the Block Browser, element suppression in simulations, global material assignments in simulations, etc.
