altonhare,

I don't understand why you are being so obstinate. As a layman trying to grasp GR I have found the 2D and 3D visualizations to be not just valuable but required to understanding the subject. I simply could not get it until I tossed out 2 space dimensions and focused on a 2D Time-space coordinate system. Emphasis on time.

BTW, the rubber sheet analogy was worse than useless, it set me back years. I kept imagining space as having an intrinsic pressure created by mass curvature and that is what created the force of gravity.
