I don't understand the appeal of domes compared to cylinders and other rounded extrusions. You still have the complexity of round interfaces but at least the outer surface has zero Gaussian curvature (you can wrap it with a sheet). Negative curvature (hyperboloids) can "cheat" and use a net of straight lines, so that also has nice properties. But, positive curvature surfaces (spherica and geodesic domes) require compound curvature everywhere. See also the complaints elsewhere about space utilization. I guess they look cool, that is their main feature. They also seem good for tensile structures (inflated domes) and massive self-supporting spaces. But you can also get most of those properties with extrusions, which are way simpler to fabricate.
