It’s a fine idea to start with a grid and a set of hard rules – that’s how you get clean, repeatable symmetry. But remember the mystique comes from more than perfect geometry. Ancient builders worked with the earth, light, and the quirks of materials, not with a CAD outline. If you want to capture that, layer in the subtle asymmetries: worn stone edges, irregular stone placement, the way a plaza shifts with the sun. So a strictly measured, symmetrical model is a good skeleton, but the flesh that gives it soul needs a touch of intentional imperfection.
