Is there a tutorial for creating a dome shape or can someone explain it? So far I have been lofting a circle to create the staggered base, but now I need to add the cap and I haven’t been able to figure out how to get a nicely rounded peak.

For the record, I am not a professional Shapr3D is my first foray into real modeling (TinkerCAD is what I have been using until now), so more detail on any explanations would be greatly appreciated.
