Best cad for beginner

[brumster]

For 2D stuff I get on quite well with the freebie QCAD; I've no previous background so I'm quite happy to learn what others would probably call it's "idiosyncrasy".

For 3D stuff I really love OnShape as mentioned above. Again, completely free, very easy to use for me (having come from DelCam Powershape) and when you consider what you can do with it without spending any money, it's a pretty cool tool. I use it mainly for 3D printed parts. Don't poo-poo it straight away because it's browser based, but obviously it does necessitate an always-on internet connection. If you want private designs in it, unshared with the world, then you'll hit the free limits quickly though - and then, at $100 per month, it's not cheap. Their pricing could really do with an intermediate level IMHO.
