I absolutely love Fusion 360 and I use it both for the Nomad and for my 3D printer.
I tried a few 3D apps for OS X, and as far as I know Fusion 360 is the only affordable yet not dumbed down 3D modeling solution for the Mac that also has a UI that is not unbearably ugly. It’s very powerful and fun to use.
For the Nomad, I used to export STL and import that into MeshCAM to produce Gcode to feed into Carbide Motion, but now I use Fusion 360’s built-in CAM and I like that a lot. It is very flexible and lets me combine the different passes step by step. I also like its toolpath visualization and cutting simulation. Now I go from Fusion 360 straight to Carbide Motion and it works great. I saw that Autodesk just added a Carbide3D post processor driver to one of its most recent updates.
BTW if you use Fusion 360, I highly recommend a 3Dconnexion SpaceMouse (I use the wireless model). It makes a huge difference for me, I am way more productive with it.
