One reason that I started this topic and why I am passionate about the use of MaxonForm and C4D, is that I see it as much more than people give it credit for .... everyone doesn't get the chance to design buildings like Norman Foster or Frank Gehry and so doesn't need the ability to create amorphous shapes in their software. However if the ability was there, it would be used..
With all due respect, you are talking like someone who doesn't build much.
Not that i wouldn't want freeform modeling in Archicad, too, but the whole program is so clunky at polygon imaging, it scares me to think how slow it might get with NURBS elements common in models. My public art work is quite unique with parts derived from many modeling applications. A 40Mg object that forms in Cinema 4D in an augenblick takes literally minutes in Archicad.
But i write, wishing we could more easily do freeform work with Archicad. What i disagree with is your "Field of Dreams" notion: "Provide it and they will design".
Freeform capability in software will not enliven the design world.
The mandate to create irregularity and freeform shapes doesn't come from software. It comes from a client who demands iconic, flamboyant marketing material in 3D form. Software was not used to create the Sydney Opera House or Notre Dame du Haut or many of the fine Olympic stadia of the seventies.
In my thirty year practice, deviating from the rectilinear in any respect causes immense cost increases that can be mitigated by BIM through reduced construction errors, but any lack of modular repetition means goodbye to economy. There must be a clear economic mandate to produce sweeping, wasteful forms.
The Sydney Opera House is notable for the way a complex coupled formwork for the tilted arch ribs grew so that the smaller parts repeated - an essential economy in an outrageous and beautiful structure. They used simple descriptive geometry to develop this idea. Drafted on paper, no doubt.
Your posting refers to a web site where top architects explore irregular and organic form using computer controlled cutters and 3D printing. This is fine for models, but real buildings made from those shapes still come from extruded linear panels of material, whether fabric or metal. Many of our younger users are not reconciled to the fact that buildings are largely made from sticks and sheets. They seek to manipulate an organic, sensual mercury lozenge as if it were a blob of clay and have it magically transformed by cussing men in coveralls into a watertight, energy efficient building.
Fuggedaboudit. Those guys have plenty of reasons to cuss.
At some point the cybermesh being pushed around without regard for gravity or water shedding must transform into sticks and sheets. Archicad is good at this because it forces us to make building parts responding to the realities of how things are made - by extrusion or casting or whathaveyou.
Rule of thumb: If it is hard to make in Archicad, it is going to be hellishly expensive to build.
Many of you might point to Gehry's flamboyant and delightful entertainment, the EMP in Seattle as an example of freeform architecture, but this is not true. These buildings are based in analog models, digitized. And they are also resolved using fairly simple techniques. If you were to study the structural solution of the EMP, you would see steel I-beams sawn and re-welded into torturous convolutions providing rigid - but not very logical - support to the theatric building skin above. This approach doesn't get you to the LEED gold award podium but it does draw people to your happening, man. Far out, eh?
I was visiting the EMP just after it opened and spoke with a construction supervisor. He related that when the unbent building panels were being screwed to the irregular interstitial framing [that extra matrix of sticks between organic skin and convoluted steel structure] their accumulated resistance bent the building enough to mis-align pre-drilled fastener holes in subsequent panels. And so it goes... even the finest software can still miss the mark.
All this said from a free form guy who knows how to build and was taught to get the maximum benefit from structure and materials. People: there's a material and energy crunch out there. Work in modules, already!
And don't build with rice. Rice is for motor fuel.
