Garbage in = Garbage out.
A bad design is a bad design with or without computers. The problem lies primarily in the user of the tools. Having come out of college fairly recently, I seriously believe that the number of qualified students leaving college is rapidly diminishing. Too many students are just cramming for exams and never bother to learn the real concepts behind the equations. Education in the USA is geared primarily to pass standardized exams, rather than teach you the concepts. I know one too many people in engineering/architecture/sciences who can't explain simple calculus or physics concepts, but can recite obscure formulas and equations. In the years after college, I have never once been asked to recite a formula, but I have been asked to apply basic concepts on a daily basis.
CAD is a great tool. It's helped to cut design times in half, perform sophisticated analysis on complicated designs, among countless other benefits, but the user still requires a level of expertise on the topic for the results to be useful. This level of expertise requires the conceptual understanding of math and science, not the memorization of formulas or equations, which is exactly what the newer generations seem to lack.
just my 2 cents on the topic

All plans sections elevs etc have been saved as DWGs and the project and if it continues will be documented in autocad. I will use archicad for a bit of design development, exploring better juctions etc
Even Gehry’s buildings still have (usually) flat slabs and vertical column under all the clothing

¿What happens if there was no energy, no light, no calculators? What tools you used to draw plans? Only a pencil and your hand...
It's means that there would be no architecture?

Someone had to figure out how to build it out of modular building materials. If you leave it to the contractor, he'll bring it in 2 years late and 300% over budget. Frank could do that, but I couldn't. I would model it for constructability, and Rhino, C4D, 3DS, etc. simply can't help with that.

The plain hand-drawn sketches were translated into physical mockups (clay? wood?), traced into 3D points, converted into 3D surfaces using Rhino and fully modeled into a construction model in CATIA. And AFAIK, the plans and sections are mainly AutoCAD 2D drawings.
I could certainly do the Guggenhein in ArchiCAD, but it would be a lot of segmented pieces on a helix frame that would be written in GDL. ArchiCAD may not be any good for the initial concept design, but you're talking about 1% of the overall project effort. The rest is in the details!
Use the best tools in each part of the process (or at least, in how far they work for your approach of design). If you want to start in SketchUp or with paper, do so. If you want to start in Rhino, AutoCAD or even ArchiCAD, then do so.

To accurately work out and document the large variance in the curvature of those forms and geometry, they had to use a lot of custom and specialized fabricated unit parts.

And yes, as mentioned earlier the actual design was in reality a more traditional sketch-paper/wood/clay model process which was then digitized and rationalized using a raft and arsenal of software including Rhino, CATIA and AutoCAD.
And no, you could NEVER do the Guggenheim in ArchiCAD or with GDL. For one thing, from a software-technical standpoint, ArchiCAD (or conventional BIM software) canNOThandle the ultra-high polygon count of the model, let alone the necessary degree of parametricity and parametric relationships necessary to maintain a live model. Otherwise Gehry would have used the far cheaper ArchiCAD (which did exist then or even years later when he did Disney) rather than licensing the far more expensive CATIA engine.
Additionally, a design of that level of complexity and peculiarity requires a higher level of accuracy and detail in the documentation process - certainly far higher than ArchiCAD (GDL or not) is capable of producing and handling in order to keep the construction costs feasible, let alone manageable within a perpetually changing and revising design environment. Speaking of which........

(The Disney Theatre in LA on the other hand went over budget but that had more to do with factors out of the control of the design and construction team, such as budget and cost overruns caused by the 1994 Northridge earthquake, which halted construction and drove up costs - as well as multiple design changes requested by the client).

This, obviously, was thanks, in no small part, to the use of CATIA which was already proven technology in this kind of workflow, in the Aeronautical design and Nautical (Ship) design Industries - where they have large design and R&D budgets and much higher stakes on the efficacy and safety of the finished product.
AEC design software (including everything in BIM) is lightyears behind, in comparison. So you couldn't really even begin to contemplate being able to document, let alone design a project of that level of geoemtric complexity in ArchiCAD or even a Revit or Microstation for that matter.

Is that true? True still? Is that why it costs trillions of dollars to use?
Clarence: do you know anything about cost overruns and improperly manufactired assemblies at the Art Gallery of Ontario. Does anyone know what that was about? The inside poop, as it were?

Back in the day when CATIA was used to design Mirage fighter jets, I remember reading that what made the software so powerful was that it could define the location of an infinite number unlike its competitors that could only approximate points. I thought 'defect' this due to polygons ultimately being a representation of a surface. CATIA sounds like it deals absolutely with a virtual surface.

Yes, that's how CATIA used to work back in the day, but that was not necessarily nor primarily the reason for the its power or the cost. And it has since undergone (at least one) a major or massive overhaul from that particular engine: - I believe when they upgraded from version 4 to version 5.
Incidentally, an interesting anecdote about this software engine's overhaul has to do with the direct effect it had on one of Dassault's (the developers of CATIA) biggest clients. When the Airbus was being designed, since different parts of the plane are contracted to different manufacturing plants across Europe (partly to do with the fact that the Airbus is a multinational or at least multi-country effort), this was occurring just as Dassault were upgrading the software, and certain manufacturing parts upgraded their CATIA versions to the new engine in version 5 while others kept working in version 4 and the result was one of the most expensive and infamous blunders in the construction industry when the separate manufactured parts couldn't fit together due to the different ways in which CATIA v4 and CATIA v5 calculated or geometry defining the holes that the rivets go through in connecting the various parts. It was fractional error and really very very minor discrepancy, but nonetheless one that added up to billions of dollars (or Euros) in re-designs, re-simulations, etc, and an embarrassing set of delays and overall cost overruns for the Airbus corporation. Needless to say, they have since instituted a common coordinated software upgrade policy for all their various plants across Europe. Boeing have been looking to avoid suffering the same design pitfalls with their own 787 Dreamliner design, which is also being manufactured all over the world as they have sub-contracted the various parts of the plane to different manufacturing plants - and indeed completely independent firms and companies, outside their N. American plants.
But yes, Dassault Systemes have since upgraded the software since version 4 and it actually calculates geometry differently (more accurately? more efficiently?) now that before. I also heard that it underwent another overhaul for the recently released version 6 as well.
Regardless, CATIA's power and cost, aside from the 3D engine which is powerful as it is, really lies in the modular software structure that they have adopted which allows them to develop several separate modules for separate functions which then run fluidly atop the main base 3D Engine. This allows their customers to easily customize the software to their individual needs while also streamlining how it handles and manages information across the board. The modular approach is something that GS could greatly learn from in terms of how they dispense their limited R&D resources for developing various tools for ArchiCAD - to some extent I see that they seem to be adopting this approach as well when you consider the MEP module, and to a lesser extent the VBE explorer. I have always long hoped that they would adopt such an approach to developing other features that are often clamored for by users, but which may not necessarily be considered to be nor fall under the core functions of the design and modeling engine - such as a rendering module possibly developed by a ASGVIS/Chaosgroup, but licensed by GS users directly ala Vray in Rhino and Sketchup; or a Mass modeling/ conceptual design module or a Energy calc. module, a Take-off/Quantization module, etc etc etc.
All of which would keep the main engine light and streamlined while giving the customers the option of purchasing (and directly paying for) additional modules as they see fit for their individual needs and their firms.
Dassault systems is not that large a firm neither.

It's not exactly that complex of a design anyway (morphologically speaking) aside from the curvy curtain wall/facade and the spiral stair feature that he designed.

But then again, he is currently involved in litigation over MIT's Stata science research building that he designed (they're suing him over some leaks of something of that nature.) - although again therein lies the issue of the lack of control of the design once it goes into construction, and the contractors decide to cut shortcuts, use inferior materials or methods (as he contends happened in this case under the client's(MIT) direction, to cut down construction costs).
