If you wanted me to draw an abstract floorplan of my house, or the layout of my town, I can do that easily. I can navigate an extended road trip unassisted by simply looking at a map ahead of time and mentally storing an abstraction of where I need to go. But if you wanted, say, an image of my house, or the main intersection in the middle of town, or anything like that -- I'm no good. I can't "see" it, and I would not be able to draw anything remotely accurate.
To circle back around too your "imagine" vs. "see" problem -- my response to the often-referenced "imagine a ball rolling on a table" exercise often elicits some confusion from people. I can imagine a ball rolling on a table just fine. What color is the ball, though? It has no color. What size is it? It has no size. It is just "a ball", in the abstract -- its only property is shape (spherical), which is ultimately all that is necessary for imagining rather than seeing. If you wanted me to visualize a large red ball on a green table, though, that's beyond me.
