Autodesk Labs has released a new technology preview for Inventor 2013. The new add-in is called Inventor Simplification. If you are familiar with the Shrinkwrap tool that was released in Inventor 2010 then you will realize that this is just a more advanced version of Shrinkwrap. Inventor Simplification has made it easier to simplify parts and assemblies for downstream consumption by allowing you to remove intellectual property that might not be needed. Take a look at the videos and link below to get a better understanding on how amazing this tool really is.

Autodesk Labs have a new product to assist with coordinating Revit with Civil 3D. This new add-in tool will allow the coordinates inside of Civil 3D be saved out as an external file, that can be imported into Revit to acquire the Shared Coordinates. This process appears to work without having to import the actual Civil file. A quicker, simpler way to make sure you Revit model has the correct coordinates.
The add-in app is written for release 2012, but I copied it to my 2013 version and it appears to work correctly.
