I was using Houdini when it was called Prisms on an SGI Irix machine. It is for 3D graphics and effects, not CAD or FEM/FEA. Autodesk Fusion is for creating 3D geometry and testing your design with an FEA analysis. Houdini uses a physics engine for graphics, not engineering results or stress analysis. Autodesk have now made the FEA simulation portion fee and cloud-based, when it was free before if you ran it locally on your computer. I have Houdini installed for fun, but I also use Blender (since 2000). Two different uses entirely between Houdini and Autodesk Fusion 360.
