1.) What it is? Welcome to the new world of modern architecture. Frank Gehry, who first brought curvy buildings to public attentioin, may not have been constrained by sheets of plywood, but was constrained nevertheless by architectural CAD software. He had to resort to CATIA to liberate his design. The concept of organic shapes -- and functions -- seems to now being led by the Smart Geometry organization. Bentley is a big champion of generative components ("GC," as they are being called) and has flow in a bunch of us journalists to make sure word gets out.
2.) How is it put together?  I had to look at what CAD software is and that is when I find out Computer-aided design (CAD) is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design.
3.) When I first seen this picture all I could do is think how the world is getting more creative. I would love to go see it one day due to the fact I cannot believe a build is on the water. I like the design how it is put together. I think more and more individuals are going to start using this computer-aided design.
