Depends on your definition of walk through. Like I can tell you at my old office I would walk in first door, scan badge, walk into lobby, head to the right(saying hi to receptionist and security guard) badge into office area, walk past first group of cubicles on right side, mail room on left, walk past hallway with copier, walk past hallway with bathrooms, in second group of cubicles walk past first 4 cubicles and the 5th one was mine.

I can't visualize any of it. I know it and can describe it. I could even give the names of people in each of the cubicles I walked past. I just can't "see" it. It's like reading a book vs watching a movie.

Picturing mechanical processes like how a robot works or how a milling machine works I can kinda just walk through the math and programming. I can say it moves in z- for 1 inch, rotating for 1. 5 inches diameter at 250 rpm then raises z+ for 1 inch, moves in x+ for 3 inches and repeats for 5 times. No idea what it looks like but I can walk through the math and kinda read the code in my head for how to do that.
