3D printer and CNC routers

[thinfourth]

Hi and welcome to the forum. Personally I would get my head around a decent cad cam package from the start, Fusion360 is free for hobby use and has cam built in it also is very powerful. There are plenty tutorials on the web.
Have a look here:- https://www.youtube.com/watch?v=A5bc9c3S12g

Okay

Currently to design something i can either spend some time learning fusion 360 OR i can grab a lump of chalk and draw it out on the bench.

I can work chalk perfectly

I can use the draw, circle and delete functions

Which is all of them

I have no need for using fusion 360 apart from when i occasionally send stuff off to a lazer cutter which is rare as it is expensive and a pain in the behind.

My thinking is if i have a 3D printer there is no shortcuts

I need to use fusion 360

So what else can i carry over from a 3d printer or is there no cross over whatsoever?
