This seems similar to how mine works too.

It’s as though the connections among things are dimensional rather than visual. I can “render” blueprints as this thread discussed, or know which way I’m facing deep in an intricate tube station, but am not “picturing” it, it’s just, this is how these things relate in space time. Although I can do the same with exterior architecture (is that an image?) or street corners. I don’t think I’ve ever “seen” anything: picture yourself on a beach, counting sheep, always assumed were metaphorical expressions.

I also feel concepts are dimensional, and can tell if a piece of a concept is missing because where it should be is empty. Think how periodic table of elements worked.

A red ball on a green table maps to billiards in dimensional concept space so I can render that too.
