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.
