In my previous post, I had some revolutions where the axis was off. Merging faces caused Rhino to lock up.
In trying to correct that, I have taken the Red revolution and copied it around the center 120 and 240 degrees.
I can Boolean Union the Red and Purple to Black BUT I cannot do so with the blue. I cannot split black using blue either.
I am curious why this is the case.
