CAD and CAM can be separate packages if you want them to be if you want to spread the risk of F360 changing T&Cs (no sign of this by the way). I use a range of CAD software and they all produce IGES files which you can import into F360 and make use of the extensive CAM features.

Obviously the files are not linked this way and if you spot an issue doing the CAM you have to edit on the CAD program and export again. Rarely happens in practice and well worth it for the F360 CAM features.

The Vectric stuff is great (I have some myself) but there is a cost so I would do some comparisons with F360 before deciding. By the way F360 only runs on 64 bit so bare that in mind as last time I checked Mach 3 does not so if using that to drive the machine you need 2 PCs or dual boot etc
