The Tutorial Gallery in Inventor is a great tool to create and use tutorials.
It would be great if this function would also be built into Plant 3D, Autocad and Vault.
It allows you to create tasks... at each task you can add a video and a model.
You can skip the tasks you don't need and the model/drawing will open in the state you need.
If, like me, you work with multiple Autodesk products, this could be a great help.
