We’re Going Inside : Buildings and BIM
Por Jim Foster - 3D, Built Environment, New Technologies - August 20, 2010
New technologies have developed around the capture capture of existing buildings in a digital environment. Laser Scanning comes first to mind, and now Photofly from Autodesk, however, these seem to best address the exterior of the buildings and are used in particular circumstances that warrant them. Now comes the backpack scanner, and thanks to Erik Lewis and his blog Who’s Afraid of the Big Bad BIM for bringing it to my attention and I’ll quote him here:
“Incredible. Between PKNail and emergent technology like this, I see a real future in gathering existing facilities information into BIM databases…”
Laser Backpack Creates Instant 3D Models
Very cool.
BIM CAD Throwdown : Dassault Takes Aim with Catia Live Building and Draftsight
Por Jim Foster - 3D, BIM, New Technologies, Open Standard, SaaS, cloud - July 30, 2010
Holy frontal assault Batman. Dassault, the french producer of CATIA (Computer Aided Three-dimensional Interactive Application) / Solidworks is making a strong move into the world of architecture. CATIA, generally used in the aerospace and engineering fields, has also been used successfully by Gehry to produce his curvilinear buildings. They are now introducing 2 products aimed squarely at the Autodesk Bullseye, a CAD application developed through the IntelliCAD Consortium (ITC) and the Open Drawing Alliance (ODA) called Draftsight and its going to be free, yup free. And is available here.
And while it is available for the Windows Family of OS (XP / Vista / Seven) MAC and Linux versions are in the pipeline, take that into account that IBM, you’ve heard of them, markets these solutions worldwide and that complaints about Revit not handling larger products are scattered across user groups and BIM forums one can believe there is an opening. Additionally, if they are following the SaaS path of putting Draftsight in the cloud for file sharing/integrity it becomes a pretty powerful argument to think about switching, especially if all the ingrained keystroke commands and shortcuts from AutoCAD are copied along with it. Having seen the Intellicad interface, I think that most likely a yes.
Excellent article at AEC Magazine that covers the introduction in depth, and thanks to @amonle / John Allsopp twitter for bringing this to my attention. I’ve included a portion below.
Based on a future version of Catia and its data management system Enovia, Dassault Systèmes is developing a competitive parametric modelling solution to compete with Autodesk’s Revit BIM (Building Information Modelling) tool. I understand that the next update of Catia will store its data in the cloud and Catia will potentially be downloaded and licensed from the desktop. This will enable Dassault Systèmes to overcome the fact that it does not have a value-added reseller channel to sell Catia Live Building but needs to compete with an established and low-cost player.
The brief demonstration showed an architectural model being rapidly developed and edited using Catia. Bernard Charlès said that the new product could do modelling in seconds, what Revit would take 45 minutes to do. And Dassault Systèmes should know — it was among the many original investors in the start-up company that developed the first version of Revit.
While Revit has captured the mindshare here in the US and Down Under among other places no one can discount the Dassault / IBM alliance and their entrance into the AEC industry in a big way. The amount of consulting opportunities and hardware sales should have IBM salivating. So if Draftsight is free, what is Live Building coming in at?
CAD Market / BIM Market 2010 : Installed Base : Ouch.
Por Jim Foster - 3D, Autodesk, BIM, Installed Seats, economic trends - May 6, 2010
So earlier in these ruminations I stated that I thought 30% less was the new watermark, that is, 30% less work out there, 30% off what used to be a winning bid. Early market data from Jon Peddie Research, shows a 22% drop in 2009 CAD revenues as compared to 2010. This is just on the software side, not services, which we can argue would be worse. Subscriptions are down because why renew an empty seat as are new sales. This report deals with CAD on all levels from designing parts to designing buildings but still gives a good overview of the industry. The good news for those embracing BIM is that they reaffirm other anecdotal information that BIM is a bottom up phenomena not a mandate from management. That is, the people building the buildings are the ones who are using not because of perceived value or marketing spin but because it adds value. Hammer..check…Compressor…check…BIM model…
Updated Aug 2010
I noticed a lot of traffic to this page, and also noticed that the link to the report required a log in so decided to quote it here.
Let’s just get this over with: the year 2009 was a disaster in the CAD industry. According to our latest report, the CAD industry saw revenues of $5.1 billion, a 22% drop compared to 2008 and although the picture is improving for 2010, there is no rebound because that’s just not the way the CAD industry works, and worse, that’s not how this recession worked.
The CAD industry cannot turn on a dime because it’s part of larger systems. At this year’s Autodesk University, Carl Bass noted that subscriptions were down because there’s not much reason to maintain a subscription for empty seats. Unfortunately, there are a lot of empty seats for all CAD systems worldwide. We estimate that approximately 200,000 workers left the CAD industry worldwide. And, it can be added, we believe this is a conservative view.
In this latest report we have seen an interesting trend as Building Information Modeling (BIM) becomes accepted in the engineering, architecture and construction (AEC) industry. The similar discipline, PLM is just about ubiquitous in MCAD but as it was being introduced into the MCAD industry in the early 90s, it was essentially implemented in a top-down process as management signed up for the advantages that come with a consistent and connected data pipeline. In contrast, BIM in the architectural fields is being driven by those at the end of the pipeline in building and construction.
3D from Photographs : #BIM #3D
Por Jim Foster - 3D, BIM, Built Environment - February 23, 2010
The world wants an easier way to get 3D. Photographic manipulation has been around for awhile. I remember sitting in a presentation by Yonald Chery for Mok3 which created photo immersive 3D, and this was back in 2004. The technology is still used today in something called supertour. A quote from 2004 at the time-
“This Mok3 thing could be bigger than SketchUp, especially for interior designers and architects,” Geoffrey Moore Langdon tells me. “It is like a PhotoShop that allows you to push-pull the images into correct 3D with the ease of SketchUp. Thus from a single photograph, you quickly create a 3D model:
It was ahead of its time, but we are seeing more entrants into the field. Autodesk acquired RealVIZ and its Image Modeler software, you can view a demo here. And today in the NY Times today there is the article Computers Turn Flat Photos into 3-D Buildings. Where they are using a crowd sourcing/social media aspect to data collection and improving the algorithms to stitch this stuff together. A project out of Cornell and University of Washington morphed into Microsoft’s Photosynth where you can view 3D images that have been stitched into “quasi 3D” through a browser. However, Photosynth appears to be limited by the number of photographs and data so the bigger desire was to scale this thing. So the same folks have been crunching more numbers and algorithms to create a more robust platform and a web site called Photocity was created entice people to add data and create the digital 3D construction of the WORLD, okay maybe not the world but then again…
BIM : Explode Value Engineering : #BIM #AIA #Revit
Por Jim Foster - 3D, BIM, ROI, Revit, Uncategorized, Virtual Construction - January 11, 2010
I am not an architect, nor do I play one on tv I simply have a small company that surveys buildings. While that may not qualify me to design one I have had the benefit of being in hundreds of buildings, surveyed them, see how they were put together, and they functioned with people in them, so with this little bit of information I feel qualified on commenting on architecture in general. And before I start I want to say that I believe architecture has the ability to transform and inspire like few other arts or disciplines because I can walk by a statue without noticing it (which I hope I don’t but were all in a hurry sometimes) but tougher still to ignore the building you are entering, or working in or even passing by, however, with that said I am unfortunately underwhelmed by most buildings I’ve been in or pass by, or have worked in. Too often we exist in a world that is value engineered, that is something has been designed to be produced as inexpensively as possible. I understand that, less expensively built; more people can afford to purchase; we all win, fine. Good in cars and televisions, unfortunate in buildings. We live in a center core, curtain wall efficiency that drains most of the fun, awe and art straight out of a building. And if you are trying to do something inexpensive, yet impressive this too can be a daunting task. But there are examples, artchitect turning shipping containers into homes comes to mind, like Adam Kalkin, Another is a home we surveyed designed by Carl Koch as part of community on Snake Hill. Now personally I thought it was fantastically ugly from the outside, looked like a box, seemed kind of cheap but as I entered the house, which still had all its original materials and finishes I was amazed how everything made sense, nothing wasted, coherent, took advantage of passive solar while providing lots of light and a great view, lines were simple, I was impressed but again this happens so seldom.
However, I have hope more and more architects are designing in 3D, even Architects who never once fired up CAD are embracing SketchUp as way to think and communicate in 3D. BIM allows design to happen digitally and with true BIM packages allows analysis and fabrication to build a building more cost effectively and real ROI metrics for making choices. Now this could be used for good rather than evil by providing hard bids on designs that were thought to cost prohibitive before, or proving new designs digitally and communicating them to developers and owners in 3D convinces them of their merit. What I hope is that ‘value engineering’ ceases to be a proxy for taking all the fun out out of a building but instead becomes part of the process that brings 3D digital design and BIM into reality and physical structures that continue to awe and inspire.
CAD Marketshare : BIM Marketshare : Installed Seats : Installed Base : #BIM #CAD
Por Jim Foster - 3D, BIM, CAD, Installed Base, Installed Seats, Revit, economic trends - October 22, 2009
I thought I’d share some numbers here since I find it difficult to find them openly out there on the interweb. I included a Market Share Pie Chart which appears to be from Gartner Research circa 2007. Using the 55% AutoCAD figure for the total market share and using the AutoCAD installed base via 2008 of 4,162,000, which is right from an Autodesk Press release, we then can approximate the total installed seats for CAD (2D, 3D, BIM) to be around 7,567,273. However, this figure could be derived by revenue which will distort the total installed seats figure.
If we assume that 7,567,723 figure is correct, as well as the 7% figure for Revit provided by Gartner we get installed seats of Revit to be 530,000, give or take. That seems kind of close to the back of the envelope estimates I was coming up with by getting published accounts of installed Revit seats to be around 400,000 end of 2008, and they were selling new seats of Revit at around 20,000 per quarter, would have them around 480,000+ by the end of this year 2009. If installed seats of Revit have not surpassed the installed seats of AutoCAD Architecture, previously Architectural Desktop, it has to be getting close, as of 2008 there was an installed base of ADT/ACA of 503,000.
Using the report as a guideline they had BIM growth at approximately 12%, if Revit is adding seats at approximately 20,000 per quarter that is a 15% gain from FY 2009. In 2008 they had an increase in revenue from Revit from the previous year of 23%, which could be attributed to sales of subscriptions and on going maintenance contracts above and beyond the 15% I came up with here.
Another interesting fact is that as a percentage of revenue 3D Products and AutoCAD itself were getting very close to parity, with AutoCAD and AutoCADLT at 32% and 3D Products at 30%. I am not privy to how they break out all the figures but Civil 3D, Navisworks and Revit are all thrown into that bucket. So 3D solutions has gone from 23% of FY 2008 revenue to 27% of FY 2009 revenue to 30% at the Q2 FY 2010 watermark.
Some other information I found in an article at Architosh, and I have posted some of it here.
Revenue and Growth
According to JPR’s research, CAD software vendors saw combined revenues of $5.2 billion (USD) in 2007 globally. The CAD software market grew by an astounding 20% in 2007 compared to 2006. Despite a very poor US economy and the threat of US recession, the CAD industry will continue its positive economic trend and will grow to over $6 billion (USD) in 2008. Looking out five years the global CAD software market will reach and exceed $8.2 billion (USD).
2D and 3D
In 2007 the worldwide installed base of CAD users reached 5.31 million. In 2007 the majority of CAD users (63%) are still working in 2D, while 37% work in 3D. However, revenues for 3D CAD surpassed 2D CAD taking 53% of the market. This trend will continue but JPR makes note that not all 2D CAD users will make a transition to 3D CAD.
The article was based on the research from Jon Peddie Research.
To look at the 2007 figure of installed seats as reported by Jon Peddie, of 5.3 Million and a 15% Growth Rate we would get approximately 6.09 Million Users in 2008 and 7.00 Million in 2009.
Hope this was helpful for those of you at their searching for this stuff, and if you weren’t I don’t know how you got here and why you’re still reading.
Summer Thaw, Projects on the Rise: #BIM
Por Jim Foster - 3D, As Builts, BIM, Built Environment, Laser BIM, New Technologies, Revit, architects - August 19, 2009
I have always thought companies like mine are like the canaries in the coal mine for part of the industry, like box companies as an indicator for the overall economy. When companies start ordering more boxes they are expecting to ship more product. Our company surveys buildings and provides as builts in both 3D BIM and 2D CAD formats. When times are flush we operate much like others enjoying the benefit, but as projects start to dry up, firms will immediately pull back outsourcing to keep employees busy rather than laying them off. This impacts us greatly. When the economy turns the inverse is true, and firm wary of hiring yet or not having enough stuff turn to us to augment their services without increasing head count. While I might argue that might be a prudent way to do business generally we ride the tide like everyone else. Having said that there has been a very perceptible uptick in business and companies asking us for proposals. More germane to the BIM world is people asking about Revit and asking for more Revit deliverables. A University even asked us after our presentations to deliver their dorms in Revit even though they did not even have an installed seat of Revit but wanted to plan for the future. Yesterday an architect I spoke to said they are now doing 70% of their work in Revit and that clients love seeing their projects in 3D, so even with the economic benefits of working in BIM are real no one should discount the importance of visual communication. This has been a rough ride but I believe more strongly than ever that a fundamental shift has taken place in the building and design community and investing now in training in BIM will pay dividends well into the future.
ASHRAE Issues Grant for Interoperability: #BIM
Por Jim Foster - 3D, BIM, Energy Analysis, Green, New Technologies - August 17, 2009
ASHRAE, the American Society for Heating, Refrigeration and Air Conditioning Engineers just issued a grant to Texas A&M for “ensuring that a common language of ‘energy efficiency’ is spoken by the both building information modeling software used by architects and energy analysis and simulation software”. I have not played around with Ecotect or IES enough, but I know it had required separate 3D modeling outside of standard BIM authoring software, getting to a point of seamless data exchange you would think would be a starting point not the end point, but glad we are moving that way.
AEC Edge Premiers: Industry Mag from AUGI – Focus on Revit
AEC Edge just premiered from AUGI. (Autodesk Users Group Intl.) It’s inital focus is to provideAutodesk users crucial information to “be more productive and on top of their game.” First issue seems to deal with all things Revit. 3D and IPD, and Revit in High School, which seems interesting that these deign/collobration tools are starting to far down the education pipeline. The format is of electronic magazine, where you flip pages which seems fine from a user consumption model, but web share model, and maybe it’s me, but does not seem as user friendly as it could be. For example, if I wanted to post a link to the article I just read, it is not readily apparent on how to do so, which seems counter intuitive in web dissmenation of content. Either way worth the read for those in the INdustry. And for AUGI, this is a crucial site and source for anyone, anybeing in the Autodesk Universe. They have provided, at least to me, more answers and information than any other site out there.
OGC 3D Fusion Summit @ MIT
Por Jim Foster - 3D, Built Environment, New Technologies, Point to Point Laser Technology - June 22, 2009
This event is being put on by the Open Geospatial Consortium, tough to type, tougher to say but it is one of many pushing for open standards and interoperability. They will be speaking about these issues and new tchnologies. I hope to stop by for some afternoon sessions and our lead technologist will be going so I hope to post on the presentations and findings.
