3D printer and CNC routers

[Zeeflyboy]

So stuff learnt in fusion 360 for 3d printing will be no use whatsoever for a router/plasma

So what CAD package should i use as the 3D printing guys appear to like fusion 360

I'm not sure that's true - familiarity with the program counts for something, and on the CAD side beyond keeping in mind the limitations/strengths of the particular manufacturing technology there is no difference in the fundamentals of designing an object whether its going to be printer/lasered/waterjetted/milled/whatever.

Sure the CAM side is redundant when using a 3D printer, but getting the hang of modelling I think it's a valid option... and designing the object in the first place is at least half the battle for people new to cad/cam. A workable if not stellar 3D printer can be had for not a lot these days and they are quite useful little beasts for jigs/fixtures in my experience.
