It would be great, to have a possibility to import Revit's T&P content directly into the Inventor's T&P library and can use it in Inventor's T&P projects.
In Revit there is huge database of T&P components of many companies so it can improve horrible unusable small T&P library of Inventor.
There could by some connector to online Revit db/library and possibility to import selected parts to the Inventor library.
