Well there are lots of things going on and I am glad we have made all this progress - plus my method builds upon what Oster brought to the table as well! Now, a quick thing to highlight regarding the relationship of the diagrid to the floors: Joseph split your brep into the correct floor segments however it’s evident you’re still playing/exploring - which is fine, hence my ‘loose’ approach - my recent contribution builds the helicoid using your floor levels in the sense that each point of the helicoid sections (lines) is at the same elevation of each floor, then capped at the max height of the tower. Perhaps it doesn’t matter nonetheless these are multiple/separate goals that you might eventually manage to marry: aligning diagrid lines to floor lines always versus procuring the aesthetic part. Both scripts adhere to your floors in some regard, so that’s an advantage
