I have never been able to do anything close to this, and similarly have self-diagnosed as much weaker in this "power". I mean I can visualize things in my mind but it is fuzzy and fleeting, like focusing on any detail collapses the field of view.
This episode of radiolab about a musician who can maintain a 3d mental image of four orchestras playing at once always stuck with me, and seems relevant to this topic:

FWIW this is sort of a thing that the process of becoming an artist trains you to do. I have been a professional artist for a couple decades and it is much easier for me to do this sort of thing than it was when I was a kid. There's a lot of steps involved in projecting a mental 3d model onto a 2d plane that I can just do in my head now because I've done them so damn many times.
There's definitely an innate level of doing this as well, some people start with a big boost, various psychoactive chemicals can help (I have done so much work while slightly stoned for the performance boost it gives my visual cortex), and then there is that story about one 1940s animator at Warner Bros. who got in a car accident that involved a degree of head injury, and could suddenly just "trace" stuff directly off of his mental images onto paper once he recovered.
