Go to AutoDesk and download Inventor2015 Student edition (it’s the only one that supports the apps we need from the AutoDesk exchange website). We will use one of the apps, MeshEnabler to convert our Inventor2016 STL meshes to base solids .IPT parts we can use in Inventor2015 (I will pre-populate the folders with each module with this and the scaling done, to fix the scaling issue as well, so don’t worry about converting and scaling—that will be done).
