    Do you think guys that sketchup needs to reformat itself and recreate itself as BIM tool, or either create a separate Sketchup for Architect who needs effeciency in time using Sketchup, e.g. by using a dynamic wall they can adjust its height, length by selecting just one wall and everything on its type will be automatically adjusted. And instead of hollow space inside wall they can interact with its properties by selecting it and all wall material properties including spot section can be viewed just a Revit does. I think its too ambitous but they need to follow along the flow of 3d software so they can sell the product.

      This is an interesting topic for me, and it speaks to a number of other discussions I have had around the internet lately. If SketchUp were to be "BIM", what entities, tools or other features would have want it to have?

      sawhack: It sounds like you're thinking of a set of new parametric entities (wall, floor, roof, window, door, ..?) with new tools to make them? Is there more to BIM than this?

            Haha, that's true. The earth has no meaning to buildings. Architects would prefer it if their building could float away up into space and leave the dirty soil and plants far beneath them πŸ˜‰

              If I understand the intent of BIM, it would not stop just with the building, but could encompass building, grounds, and subsystems such as irrigation, perhaps even natural subsystems, pre-existing or introduced by design. And part of BIM can include the fourth dimension, or facility life cycle management.
              @Chris: I could imagine one or two freak architects somewhere out there actually understanding building and site integration, even the site being more important than the building, even bold enough to say "don't build it, here". Build it over there. πŸ’š

              I take the slow, deliberate approach in my aimless wandering.

                Hi!
                I work at a large architectural company where BIM is growing into everything we do and leadership is pushing towards starting all new projects in BIM.
                There are still quite a lot af architects that start designing their buildings in SketchUp and then have to start all over in the CAD/BIM program. (In our case Revit.)

                IMHO, for SU to be a key player there would need to be better ways of getting the SketchUp model into, for example Revit, as a intelligent BIM model without the need to start all over.

                Having parametric entities would be a good start.
                Maybe some kind of solution where any SU entity could easily be linked to its Revit counterpart as some kind of preset so that it would be automatically substituted upon export?

                Quite often when I modify a Revit model in SU for (rendering purposes) I hear "Oh, I wish it was that easy in Revit" so I believe SU still have strengths that makes it useful in these BIM times.
                (As a side note, importing a Revit model with materials would be great.)

                  Thanks Alvin for starting this topic.

                  I imagine its the way you put your proposals that 'hooked' John B πŸ˜„ I hope we see lots of suggestions / proposals that might seed some ideas for John and in turn he will travel down the road of an SU Pro Arch version.

                  In the last couple of editions of Catchup 15 and 16 I wrote about this subject. 'What is BIM' in Catchup 15 and 'Sefaira Sustainability for SketchUp' in Catchup 16. The latter article on Sefaira, from my perspective, covered how in the early stages the building designer can to a large extent, 'get it right', from a sustainability stance. Sefaira works well with SU and is reasonably priced which is important for the 'one man show' Achitect! ...... there are a lot of them out there!

                  Chris raised the point about taking landscape into account in the early stages. I couldn't agree more and have always done this in my projects and feel its does pay off. The building will only last for a number of years, whereas the land will be there always ..... well at least until that Neutron star decides to head our way πŸ˜’

                  For me, I have felt for a long time that SketchUp needs a simple 2D 'sketching' front end, possibly for execution on a tablet, that would allow the designer to freehand bubble diagrams to get to grips with the initial design concept. This SketchUp 'front end' could also be tied in with something like Sefaira that would in turn analyse the sustainability of the proposed design concept. I never go straight into 3D when designing a building. For me and imagine many other designers the thought process is via 2D first, then sections and then 3D! Of course its possible do the initial 2D in SU but now as a 'doodle' or rough loose sketch! This ability would be good I feel.

                  Above it is mentioned that many architects / designers give the impression that they would like their buildings for be detached from the earth! I tend to agree with this suggestion. I highly recommend viewing 'How Building Learn' by Stewart Brand http://www.youtube.com/watch?v=AvEqfg2sIH0&hd=1 This BBC six part series (30 min segments) is both informative and quite entertaining. Its also turns, on its head, many preconceptions folks in general have about buildings.

                    Do a Google search on "Sketchup to Revit". There are quite a few references. One tutorial/demonstration showed that a simple model for quick visualization could be constructed in Sketchup and brought into Revit as a "mass". From that point on, all development of the model would have to be in Revit to retain the attributes applied to the model.

                    I take the slow, deliberate approach in my aimless wandering.

                      Thanks guys for all your reply

                      Here in our country, the most widely used 3d platform by small architecture firm is Sketchup because of its handy UI, easy to learn and the plus factor is its cost. I like the idea of Sketchup getting into a BIM industry because it needs to. the market of competition is now on the BIM especially all architectural firm. You guys were right that BIM only focus on a Building and its lifespan, but not on exterior such as landscape, terrain etc. It might be a plus factor if Sketchup become a BIM which also integrates the exterior sorroundings and that will become very useful especially in Landscape Architectural firm.

                        According to the 2012 "AIA Survey Report on Firm Characteristics", of the 38% of U.S. architects who have purchased BIM tools for their firms, 91% are using those tools for "Design Visualization." I guess that's something that SketchUp does pretty well already.

                        edit: I should also mention that only 27% of them are using their BIM tools for "Quantity Takeoff" or other related data/analysis tasks.

                          I think the biggest drawback to BIM is the interoperability between all the various softwares that professionals use.
                          I'm not talking about just Cad software, but all the various software used in structural analysis, lighting analysis, mechanical systems......, I think you get the picture.
                          I agree with John that parametric tools would be nice, but that they are not the end all. For example sake, lets look at what would be required in changing the parameters for a wall thickness. BIM is information oriented, and so the information affected in the simple change of wall thickness could mean changes to beam sizing, structural loading, any servicing that is within the wall cavity such as electrical, mechanical, (does your duct clear the new beam) etc.
                          So taking the design graphics to the level of building information, that is the new essence of parametric modeling.
                          Now all of this has to talk a language that all of the various software that is used by everyone on the integrated design team, can easily converse in.
                          So in my opinion, when I look at the exporting for instance dxf/dwg to other software, not just SketchUp, the outcome of this in reality, can be less than satisfactory.
                          I'm not sure if it just companies guarding their proprietary systems, because they want me to purchase their product or not, but without a universal language that has true inter-operative capabilities,.... well I just don't know.

                            @jbacus:
                            According to some comments on the AIA sponsored forums for special interest groups (egroups), many who are using BIM determine first whether to use BIM "if it has any value downstream". That is, if the project size or complexity warrants the effort, and if the client is one who may require long term BIM. Otherwise, I assume, they use their favorite 2D CAD program. Some mention their use of Sketchup, and some others pose the question of whether Sketchup would be of value to them. Still others have discussed the best alternative programs to Revit due to its first cost, even in a multi seat environment.
                            Many may not realize that there are several programs purporting to be BIM. "cad-addict".com blog has an ongoing list.

                            I take the slow, deliberate approach in my aimless wandering.

                              Why shouldn't this be Revit? Why would "the industry" seek a common language (a file format that contains all modelling data)? Isn't this optimally done by one software or suite of applications? This is how ESRI pretty much fills the needs of the GIS world.

                              Mike,

                              I would find it disheartening if John B is not already looking deeply into BIM. What are they doing at Trimble then?

                              So are you saying you think buildings should be separated from the earth? From the book 'How Biuldings Learn" I gathered that buildings are more flexible, or could be, than we might think, and certain buildings can be reconfigured, but I didn't see that it speaks against buildings relating to their site. I agree that some architects give the impression that siting is less important than what they want to design at that moment.

                                My script Calculator and My script Memo are two very interesting free IOS apps that let's you write with your finger and then does a very good job on translating your crappy handwriting to text. Calculator does the same with numbers and math. Like a hand drawn calculator. Something along the same lines would probably be doable and would let you draw a rough hand drawn line drawing and then recognize lines and annotations and automagically translate it to a cad like drawing with straight lines and arcs and such. There are already drawing apps that can recognize if you try to draw a circle and make a perfectly round one for you.

                                  I guess because Revit isn't used universally. I have dealt with consultants that use CivilFEM, Solidworks, Bentley, Civil3d, InteliCad, Vectorworks, the list goes on.
                                  People use the software suites they use for various reasons, but I just can't see everyone suddenly switching, or the developers of the alternative software just fading away.

                                    Good ideas. My question is quazi-rhetorical. I actually have not used AutoCAD for instance since I studied it, and don't like being pushed in one direction. I don't see though where such an effort would come from, as it doesn't seem of great benefit to the bigger players. Perhaps the revit file would be highjacked like DWG but look how after over 20 years we cannot get full, worry free dwg translation in many common applications. Maybe an open source platform would be the only way. And there MUST be enough CAD geeks to pull it off.

                                    This is also theoretical for me. I want to see my favorite platforms succeed, but I doubt BIM will be much use in my work, except some parametric tools. John B. mentions few architects use it for take-off in the US. That's how it is in the US. Architects don't do take offs, contractors do.

                                      I like sketchup for it's simple straightforward tools. One thing I really dislike about modelling stuff in bim software (archicad in my experience) are all the workaround methods used to build stuff even slightly off the catalog. I mean, using slabs to create stairs, empty doors for hollow spaces, beams for trellises, roofs for ramps, etc. One of the premises of bim is modelling with real world equivalents, but they often are very limiting, and when methods like the ones described above, not so useful when generating quantity takeoffs.

                                      Sketchup generic tools allow you to create any kind of real world equivalent structure, without bim specific limitations; for example, a box can be a slab, a wall, a door, etc, and each of these can be as simple or as complex as one needs. Not so in bim.

                                      If sketchup was to compete with bim, i personally would not invest a second of trimble's time in creating arch specific tools, (door makers, stairs, etc.), but would focus in core capabilities such as solid elements (stuff that not only gives out volume, but when sectioned show as filled, not hollow, better qty takeoff tools (improvements to component reporter) (fredo's area takeoff tool is a wonderful example), speed, and LAYOUT!!!! I remember waaaay back, there was some talk about "fat faces". This, if all technical limitations were solved, would be a very versatile addition to sketchup's core tools. Modelling in Bim is horrible!!

                                        We do takeoffs all the time. We have to come up with cost estimates for every project. I don't do it in any sort of automated fashion, I just count things one by one.

                                          that's pretty much how i estimate as well.. (not necessarily one by one as i don't always draw every single element but in a more area based way of thinking)..

                                          generally, everything i draw is highly customized in that it's either site specific or a new shape..

                                          point being.. i don't really see an advantage of someone like me working in a bim environment.. so if "sketchup needs to be BIM", where does that put people that don't really need it?.. do those features etc disappear unless called upon or will they change the flow/conventions for everyone using the app?
