I wonder if you may have aphantasia, and I also wonder if it may be more common (selected for even) amongst engineers.

If I say: "imagine a red triangle", can you do it easily? Is it red? Does it visually exist in front of you?

I have asked many people this, and many people say it is laughably easy. This tells me it is "normal".

I can't do this. I also have a terrible episodic memory. But my semantic memory is fantastic.

It exists but not in my visual field, so not in front of me. I can imagine it in my visual field but that is distinct from it actually being there, which may not make much sense unless you do the same.

I can not really imagine a whole object at once, I can only easily imagine the features/edges individually, although I know that they form a triangle.

Not sure if it's a useful data point, but my ability to construct things in my head improved dramatically after I'd been messing around with CAD for a few months.

My guess is it just got my brain to improve it's ability with that stuff, and the side effects helped in other areas (like this) too. :)
