What the heck is a booleansplit anyway? Boolean Split is a tool used in the 3D CAD program Form-Z to divide one object with another. I’ve been using Form-Z as my primary CAD program since 1995. “Booleansplit” became my AIM handle in 2005 when I was sitting in front of the computer trying to come up with a good screen name while designing some iPod accessory or another. The name stuck and I used it as my screen name last year when I joined Flickr. The rest, as they say, is history ;-)
