And you can emulate Gehry's work, with some limitations.
Remember that the sensuous forms of the EMP, Bibao and Disney Center aren't initially created in a computer - they are modeled with blobs of tissue paper, etc and then digitized.
This is more than an afternoon's work. The truth is the Catia/digitizing is not like pushing a puddle of formable mercury around your desk like we might hope but a painstaking extraction of analog model data that can also be achieved in ArchiCAD.
I've played with parametric, diamond/rectangular tiles that interleave and mesh components that describe double curves. The attached image [EMP, Seattle] shows how one might address the roll under with meshes for more fluid form, since ArchiCAD meshes cannot "roll under" from the vertical.
When you think of these forms as tiled structures made from manufactured components and not amorphic snot blobs, it helps, because ArchiCAD works that way. Besides, ever look at the fit and finish on the panel edges Disney Center? Shame. ArchiCAD can easily make a mess like that.
I got to talking with the project manager/cosntruction deficiency stooge at the EMP shortly after it opened. He was running to the bar with a length of hose to cope with a beer overflow. DNC and I know this bar well.
The builder guy told me that they had done the skin fabrication drawings in CATIA and the panels had been meticulously resolved, but there was a problem: as the flat panels accumulated on the segmented steel building ribs, their accumulating resistance to being curved to the support began to distort the structure so that overlapping panel holes didn't align.
And so it goes. Installers to the rescue. [Adjective I wouldn't want my mother to read] computers. Send some lads with plenty of rivets and a gutter machine.
We often envy the guys who work with these viscerally-exciting floppy pillow-forms, but they have their challenge. I imagine a frustrated project manager at Gehry's office:
"Why can't we do something straight."
This just before he quits to build Wal-Marts. There's a theme I understand.
Wal-Mart: Keep 'em shopping
Jail: Keep 'em in.
