It's a block language where you program the object rather than manipulate shapes. It works well for my brain. Ymmv

Grasshopper for rhino is awesome too. It's actually really relevant for this topic. It's the only syste I know that integrates so well into a precise cad design system and also allows you to do complex stuff easily. I love it. Drawing a stellarator precisely is probably not that hard on it... Will see if I can throw something out quickly today.

For me CAD is pretty much the opposite, I rely heavily on the apps, I spent about a week trying to learn to draw before deciding I didn't really want to spend months or years on it.

I'm not a mechanical engineer, I mostly only do incidental CAD and hobby level work, so it's not really essential to have the deep understanding of space that real MEs need.

I often don't know what sequence of operations I'll need until I actually open the app. Generally it's more of an "Oh I need a mounting hole, lets look around on the screen and see where one could go" thing, a lot of the thinking is in the app rather than in the mind.

Of course you can't make nicely parametric things without a lot more thought so I will often wind up having to redo things that aren't one offs...
