Yesterday, I read the news (oh boy) about a lucky man who made the grade…
Photos of the “Italianate villa” showed rooms with intersecting vaulted ceilings that inspired a GH quest:
My first effort used mirrored BiArc curves that worked fairly well but could produce wiggly lines at the intersections, depending on parameters. So today I tried half ellipses instead and discovered magic! With ellipses, the diagonal intersections in top view are always straight lines. This is wonderful!! The X and Y arches can have different widths but all have the same height.
These are the inputs:
“gap” is the dimension of square columns, not included in the model though easily could be:
Kind cool, eh?

P.S. Here is the BiArc version, deprecated:
