http://www.ohyeahcad.com/ifc2skp/index.phpQuestion? Is there an SKP2IFC ?
Update: I checked their forum at: http://ifc2skpforum.websitetoolbox.com/
and they mention almost 2 years ago that the SKP exporter would be out 'in a few months'; the world is still waiting... -

Thanks for that Dan. Yes, a system that works the other way around would be much much more relevant. Going from Revit to SketchUp is putting the cart before the horse (as far as I can see). If this ever becomes available I would love to hear about it.

Interesting post over at Google Groups: -
I'd like to point out that while all of your comments are PART of what BIM is, it is not complete.
BIM is taking parts and putting them together to make a finished product. BIM is able to categorize how many lineal feet of blueboard you need. BIM is making a change in the process (like changing a window), and it will autoreplicate through the entire project including the bill of materials or estimating form, thus giving you a revised cost of the project. For Civil folks, BIM is knowing how much dirt is needed to haul away or bring into the site. It is knowing how much 24" diameter smooth-lined plastic pipe (SLPP) is needed, how many type-c catch basins. It is knowing when there is an interference (two items trying to occupy the same space).
Having said that, SU can use components, but (unless I am unaware of any), be able to track quantities used for estimating. I think it is completely doable, but would take massive work to really be called a BIM system.
My thoughts only.

Unfortunately, Mac users are out in the cold with this software as they only have PC.

In my mind it is pointless tinkering around. Building and allied industries and consultants need a complete change of approach, getting rid of paper oriented processes and rule of thumb allowances. Only then can a proper transition be planned to accommodate the reactionary majority.
Don't you think?

As I read through the entire thread I was thinking something similar. Rather than asking, "How can we use Sketchup like BIM to get 2D drawings out of our 3D models?," maybe we should be asking, "How can/should we use Sketchup to successfully document our design?"
In essence, CAD is digital drafting and BIM is 3D digital drafting. Neither of these tools really change the way we communicate our designs to contractors. Sketchup has changed the way many architects design and how they present that design to clients. I think the time has come for it to change the way we document our designs as well. As of today we are stuck with handing contractors our design in a 2d format (paper, PDF). However, what we put on that 2d page can make a huge difference.
Here is a real-world example to illustrate...
I was asked to design a small addition for a young couple near where I live. After the design was finalized, I created a detailed Sketchup model built the way it would actually be constructed in the field. From that Sketchup model I extracted categorized 3d views which relate directly to the sequence of construction (demolition, wall framing, interior trim, etc...). These 3d views include quantities and sizes which relate to that specific construction task for contractors to price. Furthermore, these tasks integrated directly with industry standard construction specifications. In the end, this work leverages the information in the 3d model into something which truly improves the way we deliver a design to a contractor. It makes the 3d model more useful and the designer a more integral part of construction. I can say from experience that this work was extremely well received by both the client and contractor. In the end pricing the project was much easier and the the finished product was exactly what the client expected.
So although the title for this thread is "Could SketchUp be transformed to a BIM or PEN System?" I think we should be asking ourselves if that is really the direction we want to go, or if Sketchup gives us the opportunity to do something even better.

What a welcome first post. I think we are of like mind. Please have a look at this 3.5 min video, and if I am right I would like to start a JV-type topic with the caption "Using Sketchup to communicate instructions."
We can agree on the exact wording but I want to get away from document and emphasise instructions. I say this because buildings get built by instructions, simply put, "buy this, put it there". These instructions are currently drawn from interpretation of orthogonal drawings. The form of instructions is not so important as first realising their significance.
I think the forum will benefit from a fresh look at this subject.
Thanks
Edit: These instructions are currently drawn from interpretation of orthogonal drawings.

As far as I have experienced, a program that is capable of doing everything compromises its parts. If the architectural process is design, production documentation, and construction, then each phase is best represented by a program designed accordingly. To make the whole work, at best each phase must output "something" that can be easily used by the other phase, ideally in both directions. I believe that SU is a ideal product between "bubble diagrams", and 3d models of a design. LO is a program that applies itself to presentation, and Su via file transfer, to 2d production documents.

Please understand that I am not talking about a program but a scheme, something more akin to the characteristics of the web. People use specialist devices to participate in the process of creating or even using a building. Models - components, sub assemblies, buildings - attract and hold data and interpret it for various needs. There is no passing of output. The only physical output is the real thing.
I think, if I might say so, you see computer programs as solutions.
They are not, but they could become enablers once the method of the working was changed. This would define the real objective - for Architects I hope this is the creation of a building not a beautiful set of drawings - and open up use of the web with multimedia to communicate the instructions that get buildings designed and built.

The good thing about SU is the way we can sort of directly manipulate the model by pushing in and moving right until we are satisfied. Using BIM packages still resembles more filling tax forms than sketchupping. That's why I am still dreaming of a SU with a more direct link into BIM rather than increasing the BIM'ishness of SU.

Anssi, I agree. Its like a "one-in-all" solution that takes 10 steps to dimension a edge, vs. a dimensioner that will do it in one step. If however, someone comes up with a "all-in-one" that is all in "one step", then OK, I will be among the first to stand in line to get one (that is, after the first service release:-).
Chris, what you propose is conceptually elegant, but beyond my ability to grasp "the mechanics of". Besides, I like beautiful "working drawings", and will be sad to see the day they are gone, just like my overnight color pencil sketches.
Sorry for all the "off posting".

hi all, for my two pence worth,
I also, I like my working drawings, and I want to bury all the boring details inside them.
I can do this by adding layer upon layer of digital information, but I need a digital management tool to navigate quickly from grouping to grouping.I see Chris's tool as a PushPull tool for digital information, which lets me stay in SU longer, giving me more time to do additional renderings, which being part of the single information package can be presented at every possible opportunity I choose. Each project contains all it's own ideas, content, ingredients, I find that fantastic.
I'm trying to help get this working on Macs to give me the single document functionality that is already available to the brave PC user's amongst us. No doubt it's got a way to go before it's a day in day out functional tool, but it can be if people help develop it.

keep up the good work chris..

Yes that is exactly why I was attracted by Sketchup. I just want to make it better by capturing information at the very moment it's needed to make a model. In this way you have both the model and its data available for scrutiny all the time. If you want to delay a decision about placement or procurement you can test the financial and temporal consequences prior to doing so - perhaps a basis to detach the building industry from its outmoded ties.
@honoluludesktop said:

The mechanism is the concept. I am sorry I find your post surprisingly paradoxical and reactionary, so cannot really comment further.
@driven said:

Yes I think that it is a good way of putting it. The key, like bar coding, is to give components identities and link them to a digital record. Given today's amazing communications technology data can be pulled and pushed around to provide pertinent multimedia displays.

Not just the project but also each component.
Thanks for your support and particularly your efforts to make it Mac compatible.

I am of the 'old school', I started with a pencil, drawing board, T-Square, Set Square and Scale Rule and later on an adjustable? ...... God I've forgotten what it was called ..... eeeeerrrrr .... hold on! I have it now, Adjustable Set Square! Boy were they handy, saved all that messing around with the protractor
I had no difficulties in producing plans, elevations, sections and isometrics also the occasional perspective view for jobs. When computing came into the picture it should have made things simpler BUT this was not the case IMHO. Things became somewhat more complicated for me until SketchUp came along. I initially worked on MicroCAD, this was a decent attempt at 3D. It ran into financial difficulties and was shelved. I was then stuck with AutoCAD ..... the adapted Word Processor Program for draughting!
Mike
Very good comment you are making. I think what made these "old School" production methods work so well is that you were intimately aware of what you were doing. With all this technology we have lost awareness of what we are actually doing. I'm looking in to making a ruby script that can make the classic architectural "axon" using a 45/45 triangle. Simple to do on paper - once you know how to do it - and, I hope, simple to learn to script. Programming things was not what I concerned myself with when I was in architecture school and now I'm kicking myself!

it is amazing how some software developers do not realize how much they are losing by not porting their apps to mac. we architects are dying to find an affordable alternative to giants like autocad, archicad, vectorworks and the like but the developers of cheaper and less complicated apps either stick to the windows platform (this is for you, DoubleCad people) or, when they opt for mac, they not always produce competent stuff (i am here thinking of PowerCadd which could be an alternative but has lousy and insufficient documentation: not a single video or tutorial is to be found in their site).
I apologize for the ranting, guys.

Well yes you were but is a drawing (what you were doing) what you really need? I mean you used to need a cheque to draw cash from the bank. Now you can use an ATM. By doing so you minimise human effort and error. And you don't need cash cheques anymore.
@unknownuser said:

I think the awareness question is more what we want to achieve - the creation of a building or the creation of a beautiful set of drawings?

Chris,
In short I was making two observations about the role of technology in work produced and might have muddled them together.
- There is a lot of "tail wagging dog" going on. That is, programs forcing the designer to do what is easy on the program.
- To modify the program to your needs is a whole new and largely unanticipated project on top of existing projects. (BTW people that participate on this forum are largely in contradiction to this statement. Way to go guys!)

Yes I quite agree, and more than this technical prowess can overshadow real creative achievement (something tangible rather than more general "creativity") - looks good must be good kind of thing.
@unknownuser said:

Also agree and have suggested re-looking at the whole design/build/use/recycle process bearing in mind what technological advances have been made say since John Walker started Autodesk - Internet communication and software, 3D modelling, animation, file sharing and so on. Nearly two years ago I posted this short video which you may find interesting or disturbing.
