We're having a presentation/discussion on the workflow of Autodesk Inventor and Autodesk Revit today... I'll fill you in later on any good tidbits of information that come from the meeting, but for now you can reference these documents to get your feet wet.
AEC Edge has a short article on the subject. You can download the latest edition here.
You can also checkout this Skills Builder provided by Autodesk here.
I work at Eppstein Uhen Architects (EUA) as a Design Application Specialist. I focus on all aspects of Building Information Modeling (BIM) and Integrated Project Delivery (IPD) within our firm. We use Revit Architecture as our BIM authoring tool.
