I was absolutely terrible at this until I got into 3d modeling. After that, I can almost instantly rotate a shape in my head.
This is something that can be learned. Blender is a free 3d modeling software. If you decide to use some tutorials to make even some rudimentary shapes, after a while your brain will be able to turn things around more quickly. This is because you have to rotate your scene pretty constantly around whatever you're making. If you get into texturing by unwrapping UVs (It's kind of a drag) that's even better practice.
