I'm not sure what it's called, but the thing in the middle, I've been able to create the triangular arch, but I don't know how to fill it, would I be better off trying to create a model instead?
Just to make sure I'm clear, I don't plan on using this at all, I'm just doing this to learn, and have no plan to release anything, which I'm pretty sure I'm allowed to do, if not point out otherwise.
