I do 3D modeling and design and I am a hard #5. Can’t see a thing unless I’m dreaming. But when I think about a part or machine I’m designing I do have an awareness of it in my head, but it’s like it is related to my proprioception (the awareness of where your body parts are) instead my vision. I can imagine the surfaces of what I’m thinking about, and how those surfaces will interact as things move, but can’t see them whatsoever.

I didn’t know real visualization and aphantasia were things until I was well over a decade into this career, haha.

That is a pretty low bar.
