.......Concerning the blobbytechture discussion I don't want to defend the lack of Rhinoesque tools in AC but what do you actually want in terms of free-form-modeling for your daily work as an architect? How much would you use unlimited lofting and blending etc? If you want free form you want totally free form and that's why ZH and the likes use Rhino! AC is very focused on what it is supposed to do. I would myself like to play with free form modeling...of course...it's fun! However it's not very clear to me how to implement it into the BIM model. How would you like "freeform" to be incorporated in a virtual building context? Would it be a separate module? Maybe the modeling issue would be a thread of it's own...Organic/free design from a BIM-perspective!?

.......this discussion has been had and beaten to death on these boards (do a search). One of the salient points in all those discussion is that those who request these Free-form/Organic modeling tools (read better modeling tools, period) are not necessarily interested in designing Zaha-esqe/Gehry-esqe/Blobitecture buildings, but rather for some of the more mundane common-place architectural design tasks that typically require work-arounds with ArchiCAD's current toolset. Tasks like design and modeling of custom-profile stair rails and handles along with railing handles; Roof Fascias with customized characteristic profiles and sections; Custom-profiled Window and Door architraves of potentially vaulted and non-rectilinear doors and windows. And let's not even go into just how plain old custom door/window/stair/[insert generic architectural object not available in the libraries, here] creation is routinely hampered by the limited capacity to just plain model what you can envision and conceive in a straightforward way.
These are objects that exist in Architecture today and have existed in Architecture for the better part of the last couple of Centuries. Not some fluidic blobby looking thing that someone's submitted for a design competition.
Yet try designing one of them without the aid of some work-around that may not invovle have to go back to AutoCAD or even just "fake" it in today with AC12's toolset, and you have another thing coming.
Every single time this issue of better design and modeling tools comes up, someone inevitably attempts to diminish and dismiss it by proclaiming that not everyone (or more specifically, them, in particular) needs to design blobitecture or organic-looking designs in day-to-day architecture, and therefore nobody needs these improvements in ArchiCAD. Which would be fine if that was the point in asking for the improvements but it's not. And it rarely ever is.
If I wanted to design a organic looking curvy building, I would never look to ArchiCAD to try to do that, nor would I want to; there are far better tools out there for that sort of thing. If, on the other hand, I wanted to design a double curving ramp with a customized slope, variable width and customized railing, I would like to hope that I would be able to do it in ArchiCAD in a somewhat straight-forward and logical way, without having to resort to 1001 work-arounds or to ArchiForma or some other third-party plugin or addon (which obviously means having to shell out more money to get them and then spend more time learning them, and then hoping they adequately address the design requirement and then that they document correctly in all views and are respectively parametric like any other ArchiCAD library or gdl object, and finally that they don't bog down the program with a massive polycount - currently a tall order for ArchiCAD, if you ask me).

I do not think you are answering Mat’s point here and that is: How to implement the free-form modeling into a BIM model. Yes I agree that you do not have to be ZH or FG to find yourself in a need for free-form shapes. The question is how to implement them. Should we have a free-form modeling mode with dumb (in terms of BIM) surfaces (aka Revit) or tool based free-form modeling methods?
Personally the first one is not the way to go - there are much more sophisticated applications for this - a good parallel would be GS’s aspirations to make Plotmaker Illustrator-like (or desktop publishing -like) software. They had learnt their lesson that the scope for this is far beyond the purpose of their software.
Second option based on tool modeling enhancements is more appealing (at least for me) as it preserves BIM ‘awareness’ of a created object. However this option will be facing inevitable limitations because of its very principle - eg. a slab cannot behave (meaning symbolic plan presentation, dimensioning, listable properties etc) like a wall even if they are modeled to the very same shape. The only complication but the fundamental one is that basic AC tools (slab, wall, beam etc) have to accommodate symbolic representation which does not always work with free-form shapes when they interact with surrounding elements as apposed to library parts which are self-contained and isolated blocks on a plan.

Just to shine some light on the difficulties with "BIM"-objects.
We're currently testing trapeziod corner windows with the GS programmers and even that seemingly simple object raises complicated constructional issues since it can be solved in so many ways (IRL that is and BIM modeling should be like IRL). It's pretty simple to make it "manually" but would be more BIM to have one object.
Concerning simple "non-BIM" objects I agree totally with Bricklyne and I would also like a Maxon-like tool set integrated and with AC UI.
I know AC13 will, amongst other things, continue to bring improved workflow (how boring does that sound...however professional) that will shorten the time from start to finish = money/time in your pocket.

As i read i can see that BIM is limiting u and something that sould give us better workflow is now stoping u to develop new features... I dont want all to be BIM. It dont have to be 100 % BIM...Is it enough to be 93.4% BIM for you?
... such 64bit to enable AC to address unlimited RAM to load the entire model into memory and avoid all HD access. Full multi-core awareness another. The hardware required is now a realistic option .. the software just has to catch up.Owen, I do not think it is just hardware. I believe that the underlying layer of maths and geometry is already built in AC. I reckon the UI design is a tremendous task - how to deal with 3D modelling in 2D plan/S/E (meaning editing hotspots, methods, material mapping and whatever you can think of). Each individual instance has to be addressed carefully. A good example would be CW - I hate the fact you cannot edit it on plan and I can tell you GS would be probably the happiest punter among all of us users to get it done just to avoid all that abuse we have given them for this (which I have done with a pleasure and satisfaction at the same time ). The point is that apparently there is a big problem to solve 'duality' of architectural representation with current AC resources.

Try to implement BIM functions to a free-form app. Visualize Rhino with archicad's plan- section representation, story handling system and scheduling functions. That would be tempting.Petros, this is the actually the most difficult way how to do this. How would you extract all this information from a blob of play dough which the model in Rhino or similar virtually is? how would you identify, transform and chop up whole model to pieces which make a sense to a builder / subcontractor / quantity surveyor etc? It would be a tremendous task to address this with current UI. Do you really think this would be possible over one, two or even more years of development? ... and actually can you give me an example who has done it successfully? You have to be kidding yourself mate. We do not have finalised tools for a simple documentation in AC12... get real.
