I will admit that I am not a professional, but in my spare time I have designed some parts in CAD software (Fusion 360) which I've then 3D printed. My experience was once I understood the key bindings to manipulate the view, it was very easy to spacially understand what was going on, even with parts that had layers hidden below other layers (you just turn off the layers you don't care about). I'm not really sure how a VR headset would have helped in my case, but as I said, maybe this is just because the work I was doing was simple.
