I like what you’re attempting with the relative item @Bilan_Gumus , yet I think the true highlight is your shift in direction via a more manageable geometry.
Please pardon this insolence:
I trust it sparked good redemption as your efforts now prove. Very inspiring!
I took another look and I think you can re-utilize the diagonalize method you were suggested previously before you opted for the diagrid alignment relative to your floor levels. You should obtain what you’re onto at the moment without having to clean up those gnarly lines provided you use the current point setup to obtain mesh quads, unify them, then convert to diagonal mesh as shown below.
Here’s an example:

P.S.:
The modeling class I’m involved with this semester starts today - I am using you as an example of persistence and determination.
