Check this as well… You should change your rhino absolute tolerance fr 0.001 to 0.01.

I can’t read your R7 .3dm file in R6 so started with @HS_Kim’s code that has your geometry internalized.

I manually selected two of your breps and stretched them in the Y direction so they won’t fail to RUnion, but there are other poorly sized walls that also fail. I haven’t got time for the pain (Carly Simon). Oh, and I divided area values by 100 because they are so large (millimeters?).
