Hi @Anonymous,

This is an AutoCAD forum so I am pretty much useless on these topics.  I would personally try 123dCatch and see if that is something you can bring into  Fusion 360.

I did a quick model on the site and then downloaded as images, mesh, and as STL.  I then used Fusion 360, went to the Insert menu and selected Insert Mesh. I was able to insert my STL file.  I hope this helps.

I would also suggest that you post on the Fusion forum as it will be much more useful regarding this topic.
