Absolutely right - I've run a few "intro to F360" sessions for fellow club members and I reckon the ones that have the biggest problems are the ones who come to it with a "I've done lots of 2D draughting and 2D CAD" approach. They have to go through an unlearn cycle before they can pick up the new ideas! Building a 3D model is not the same as creating 2D engineering drawings, and especially not if you want to get the best out of it.

As for things going wrong when you're not looking - between my last run of my router and the next "switch on from cold" session (no more than overnight) my machine managed to break a limit switch wire inside a junction box; as there were two switches in series, this seems to have also caused one of those switches to self-destruct. Symptoms were axis moving slowly in wrong direction when homing, which was really weird to see. I no longer believe that a machine won't develop a fault if you only turn your back on it for a little while even while it's switched off!
