I agree 1,000% on the safety and undo issues. Also Parametric CAD is different from a GUI design application as in a parametric program you just setup parameters and you don't really draw/paint/modify on the screen as you will do Solidworks and Illustrator like programs.I drive parametric CAD (self taught) as a hobbyist and I'm learning to fly a light aircraft.
CAD is the easy one, and I'm a pretty natural pilot according to my instructor.
Penalty for failure in software is zero. Don't be afraid of making mistakes! The undo button has godlike power. Steep learning curve at the very start, but there's no black magic to the basics and there's an incredible amount of excellent free tuition online.
In the aircraft you're training carefully not to make mistakes with the penalty for doing so being huge. In software, I'd highly encourage you make as many as possible while learning
What I was referring to is the use of the mouse and KB to actually operate Solidworks and make it behaves as you want it to in real time, it is a learned muscle memory, it is kind of a delicate dance. In my mind it is a bit analogous to a stick and rudder work on landing with strong crosswind... You don't have time to think, you have to act intuitively with what you learned and practiced hundreds of times.
