At the end of the Construct 3D Conference a representative from Autodesk introduced a new feature in TinkerCAD that allows you to go back and forth between TinkerCAD and Fusion 360 and back to TinkerCAD. There is also a new feature similar to the old 123D Make (now Slicer for Fusion) that allows your model to be created using Legos. It spits out a BOM and displays the build order as well. They also showed a new integrated circuit feature as well. You can email above to get the demo versions for these.
