I’ve gotten so many questions about how to learn Revit, what technology to buy, etc. lately and so I wanted to respond in what might initially sound like a surprising way…STOP!!! Don’t stop asking, and don’t stop pursuing, but stop and think and ask yourself a question: Why? Why am I learning Revit? Why am I purchasing expensive technology? Otherwise, you’re just throwing money at something that you’re hoping at some point you’ll understand. Not to sound like Mr. Miyagi or anything, but, understand first, purchase after. Revit Essentials or Advanced? 12 gigabytes of RAM or 24? You certainly don’t need to understand all the ins and outs of your company’s transition to BIM, but strategize a bit. What are you trying to accomplish? Do you even know why you want to go from CAD to BIM (and your answer shouldn’t be because everyone else is). And it also can’t just be because the project requires it. Do you understand the difference between Revit and BIM? You shouldn’t be transitioning from AutoCAD to Revit. You should be transitioning from a CAD-based project process (which used AutoCAD) to a BIM-based project process (which uses Revit – among a lot of other applications). You need to take two approaches: project process AND technology. Your project process WILL change. How and what pace is up to you. Your technology will need to change also, but you should understand why before you purchase it. And when buying more powerful technology for the new software and processes you’ll be going through, don’t buy cheap. And I say that because “cheap” will WILL WILL cost you in the long run. I promise you it will. You can buy inexpensively, and you can find deals, and even negotiate, for what you need. If you’re purchasing for commercial purposes, technology shouldn’t be free. You will spend more time getting “free” things to work for you and your business and, again in the long run, it won’t be worth it.
Now, you may be asking yourself, “why is Scott ranting like this?” For too long now technology has been an after thought. It has been thought about and budgeted for way past when it should be and you end up backing yourself into a corner. Then you either buy too much, or even too little, of what you need. But Scott, you say, why is anything you’re saying new? Hasn’t it been important to plan for technology all along? Of course it has, but these days the change in technology is not simply an upgrade in software or a better graphics card. With the introduction of the Cloud and new found abilities to move design and construction data between different analysis applications to improve outcomes, we are once again finding ourselves both having to adjust our processes AS WELL AS investigate new process that can make our work more efficient and more effective.
In recent weeks I’ve been told that I am idealistic and that I wear my ideals on my sleeve. My answer was that in my job, I had to be. But it made me start to think about how any big change happens. Usually, it’s a small group of people who, not only have a unique vision of how things should be but, more importantly, know how to implement that change. It reminds me of a quote from Margarey Mead, “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.” If people who are trying to direct and implement change become intimidated, or doubltful, or waver on the belief that their ideals are right and worth achieving, then they have already lost. So this post is for people who are in my role throughout the world: do not stop trying to achieve the ideals that you believe in. While we all work as individuals trying to improve ourselves and our companies, each achievement that each of us makes in the service of a transition to a new and better way of working, helps all of us.
On June 12th of 2009, the United States government mandated that television stations nation-wide must broadcast exclusively in digital format. Did some people have difficulty with this transition (i.e. rural communities, the elderly, etc.)? Yes. Did the government make an effort to help with the transition (i.e. vouchers to be used towards a low-cost converter box)? Yes. Was this transition necessary? Of course. Why? Because sometimes a society needs to be pushed a little bit in order to make it over a large hump. The transition to digital broadcasts was not the end of the story, it was the beginning. By requiring the use of digital broadcasts, other technologies developed by the marketplace could finally move forward, which benefited the entire country, because they relied on the digital signal. The point of this is that, like the digital broadcast mandate, the design and construction process of Building Information Modeling is just the beginning of a transition which will usher in a whole host of better designs and more efficiently constructed and performing buildings. We just need to draw a line in the sand and then hurl ourselves over it. To be clear, I am by no means saying that BIM is a panacea. It’s not. If for no other reason, there are new hardware and software technologies, as well as other new processes, which haven’t been developed yet. The point is, though, that those things can’t be developed until BIM, as a process, is implemented throughout more of the AEC industry.
I know I’ve said this before, but it bears repeating: the transition to BIM is not as simple as uninstalling AutoCAD and installing Revit. BIM is an overhaul which requires huge changes including schedule, staffing and fee shifts, time for training and a learning curve (which will be a different lengths for each sector of the AEC industry) and the time to develop resources so we can reach our potential. These resources can include content, standards, data/information exchange and process development (i.e. how to we use BIM to determine environmental impact? How to we perform the test fitting task to understand which space is the right one for our client? How to input and then extract the right types of object data in order to perform highly accurate cost estimations?).
Understand what your work environment will look like when BIM is implemented, whichever sector of the AEC industry you work in, and then develop a plan to get to that place in the most efficient way possible.
As I’ve stated before, BIM is a paradigm shift from the way we’ve worked before. That goes for whether you’re in the architecture, engineering or construction industry. We’re not swapping out one software application for another. I’m not even sure there’s a “one to one” swapping of 95% of the traditional (usually CAD) project process for the new (BIM) project process. That being said, a destructive approach (i.e. wiping out the entire project process and starting from scratch) is neither realistic nor feasible. So, if we can’t swap out 95% of our current project process, and we can’t wipe out our current project process all together, what do we do? The answer is, targeted changes to specific parts of the current project process. Here are some examples of areas that will change:
As I write this, and think about it, we really are applying a destructive process, it’s just hard to see it because it takes a long time. If there are 10 steps to your traditional project process, a year from now those steps might be unrecognizable. The point is, an analysis of your current project process will allow you, and your BIM Advisor, to see what the most essential, immediate and easily changeable steps of your project process are. After that, you can devise a plan on how to integrate them.
I’ve also been saying a lot that BIM is not Revit, and that Revit is just one piece of software under the BIM umbrella. Your question to me, then, should be, How and where does Revit fit in? Revit starts and facilitates the project process. Revit is where design and documentation initially happens. It is where your building information model is born. As the design and documentation phases proceed, it is where your building information model grows. But, (ignoring home schooling) just like children, they cannot learn, adapt and mature only within your home. They need to explore, and be explored, in other applications to see how it reacts to other models (i.e. MEP or structure), how it effects, and is effected by, the environment. Once these lessons are learned, the information gathered, can be applied back to the model in Revit, in the form of design changes (I didn’t want to take the children metaphor further because it would be something like the child comes back and lives with his parents). Eventually, the model can, although doesn’t have to, leave the Revit realm as it’s given to the builders who might want to run it through cost estimation and construction scheduling applications. The point is, Revit acts as, more or less, the main software application within the BIM process.
“BIM! BIM! BIM! I’ve heard about BIM, and I want to… What is BIM? I don’t want BIM, I want Revit. I don’t want Revit, I want BIM. OK, BIM, Revit, I get it now, how can I integrate into my…” I’ve heard this a lot and and what I have found, as someone who manages BIM at an architecture firm as well as someone who consultants on the use and integration of it within the Architecture/Engineering/Construction communities, is that the more information you can give me, the better I can tailor my presentation to you about how BIM can benefit you as well as how you can integrate it into your company. The question is, why is that? The reason is exactly the same as why people struggle to get over the initial hump/learning curve/paradigm shift of a transition to BIM in and of itself. BIM involves a lotta stuff!!! Then, once you get into an actual software application (i.e. Revit, Navisworks, Ecotect, etc.), they do a lotta stuff too!! When I, and you, have a better understanding of what it is you and your organization do (and want to do), we can figure out which aspects of BIM, and its associated applications, will be most beneficial to you. Otherwise you’ll hear phrases like:
It’s not to say that a lot of these points aren’t correct but (or almost correct), but odds are, you’ll respond to me in the same way, I swear, someone did recently, “Scott, I’m going to stop you right there because I don’t know what the f*#k you’re talking about.” I actually was hysterically laughing after that was said, but it was a good point. Since then, I’ve insisted to those I was advising that they tell me as much as possible about the way they work and what they’re looking to achieve. So, the first question is, what kind of company are you? Architecture firm? Engineering firm? Construction company? The answer to this will determine the extent to which you actually need to use BIM. It’s most important to get your current practices in a BIM environment and then, once they are comfortably integrated, explore what else you could be doing. There are, however, some questions to consider that are independent of which of the three industries you’re in. That being said, the answers could be quite different for each industry. These questions include, but are not limited to, the following:
These questions, and their answers, should get you to a point where your firm is producing similar products that you were with your old, most likely CAD, system, and you are beginning to see increased productivity and reduced costs. As time goes on, personnel will become more facile with the software, they’ll strategize better and work will get done even faster. At that point, you can begin asking the next set of questions which will allow you to start doing what you didn’t, or couldn’t, do before. The following questions are the second half of the sentence, “Can the work your firm does benefit from…”:
Needless to say, there are many other things that BIM can do, but these questions, and their answers, will allow you to make better decisions when a project starts. This early strategizing informs the BIM process helping you to create what is know as a purpose-built model. That is to say, a model built for the purpose of…(see the previous list). Understand what integrating BIM into your office really means. Understand that it’s more than installing Revit. Furthermore, understand that the use of BIM, and or Revit, is not simply a technology issue. If anything, it is important that everyone understand (each up to an appropriate point) what you’re getting yourself into and how it will change everything from the software you’re using, the submittals you’re generating, the way you staff projects, assemble fees and create project schedules. Most importantly, get someone to help you. Revit is not the 2025 version of AutoCAD, and having someone who has been through it before can help you prepare for it, avoid pitfalls and help you deal with the inevitable issues that will arise.
I decided to write this post for a certain family member of mine in the construction industry who needs to be able to talk about BIM/Revit, but doesn’t really need to know all the little in’s and out’s of it. So here’s my list:
This process will continue on a regular schedule allowing each discipline to continually have up-to-date information.
The above seven points of knowledge and seven questions should give you a basic understanding of the important points of BIM and Revit as well as an idea of what important questions you should ask to begin your work. This is just the beginning of the process and Revit Essentials or Project Manager training can only increase your ability to make good decisions when it comes to staffing, budgeting and scheduling of a Revit-based project.
Happy New Year all! The transition to Revit from (fill in the blank) continues throughout the industry and I wanted to comment on the need for an experienced person on every Revit-based project. I often mention to people that nowhere within the Revit help files does it mention the specifics of how to complete uniquely architectural processes (ie. space planning or the placement of notes on sheets). These are things that BIM Leaders figure out and develop over time. Therefore it’s extremely important to have someone on your project team who has been through Revit projects before. This person is sometimes called a BIM Leader or Manager or Coordinator or any other word implying an advanced amount of knowledge and experience. It’s important to remember that that person shouldn’t necessarily be the Revit Cop or the doer of the tasks no one else feels like doing. This person acts as a mentor to the rest of the team on the best practices of moving through the lifecycle of a project. He or she advises project architects on, for example, how to verify the correct assembly of sheet sets within Revit, and/or Project Managers on how to staff, schedule and interact with consultants. The most important thing to remember is that there is no task that this person does on a project that everyone shouldn’t be able to do. At the moment, however, not everyone can. As time goes on, more and more people will have that experience and the role (which, by the way, is not an additional person assigned to the project, but a required inclusion just as a project manager or project architect would be) will no longer be necessary.
This is a quick post, but I had to mention it. I was just emailing someone in my GMail account and wanted to attach a file. In the email I wrote, “I’ve attached a file…” and I hit Send before I actually attached the file. The following message popped up:
I just thought this was very impressive. It’s all about the little things!
This past Thursday night was my last class at Pratt for a while and, ironically, the same exact last question as last year was asked: how can I use the mr Physical Sky as well as a custom background image at the same time. At the end of the last semester, I did some research and found a solution that seemed to work pretty well (http://bimuzer.com/2010/01/08/3ds-max-2010-viewing-a-background-image-when-using-a-daylight-system-and-a-mental-ray-physical-sky/). So, I tried it again and, oddly, it didn’t work. So, I became somewhat obsessed and worked at this students file for two and a half hours. During this time I found a good, three part tutorial on using the mr Physical Sky here: http://www.mymentalray.com/video.html (the last three videos called Mental Ray Sky Part 1, 2 and 3). The second video specifically mentioned that my method (he didn’t mention me by name), where you drag the mr Physical Sky into an empty slot in the Material Editor, click Use Custom Background Map and insert the image you want to use, is actually incorrect. It’s really just, “placing one image over another,” and is, “blocking the sun,” “and your entire mental ray sky map.” He says the reason for this is that the mr Physical Sky is what’s known as haze driven. Unfortunately, his tutorial had a slightly different outcome than I was looking for in that, and hopefully I’m interpretting this right, he was using a high-contrast image of clouds to create clouds in the background and have it give off light. So, I did some more research and came across another website (I love the Internet): http://jamiecardoso-mentalray.blogspot.com/2010/01/mental-rayvaluable-tips-2.html (the guy who runs this site is one of the authors of Realistic Architectural Visualization Using 3ds Max and mental ray – I have the first edition, but the second edition is now out and available here). In his article, he mentions a map that I’d never used (or really even heard of) before: Environment Background Switcher. So, I modified my own method, some things I learned in the video, and his method to come up with a new method that appears to work. Please note that the following is in 3ds Max Design 2011:
I have the following scene which has no lights, no Daylight System, no mr physical sky in the Environment Map, no Exposure Control Set, all mental ray settings are low and FG Bounces is set to 0:
If I were to render this right now, this is result:
Now if I render, this is the result:
Now if I render, this is the result:
The light still isn’t flowing far enough into the room. We’ll use an mr Sky Portal which gathers sunlight towards it and aims it in whatever direction you choose.
If I were to render now, I’d get this:
Once I increase the following settings from below the Rendered Frame Window (the Global Quality Control Knobs), set the time of day to 5pm, the time of year to 4/30/2010, as well as increase the resolution to 2231 x 1275, I get the final rendered image below.
This process definitely took some time to research and a lot of trial and error (and rendering) so I’d like to thank the various resources that I found on the Internet. Let me know if you have any questions.
I definitely plan on posting about 3ds Max 2011, but I get questions a lot to look at peoples MAX files and the first thing I usually tell them is to archive the file and send it to me. Archiving files in 3ds Max creates a zip file containing not only the MAX file, but also any other files that are associated with it (like other linked MAX files, image files, etc.). Here’s how to archive a file in 3ds max (I’ll be using version 2011, but I don’t believe the process has changed at all):
In the following file I have a simple box with a wood material assigned. The material has an image of Red Birch assigned to it:
The ZIP file created has the MAX file, the image file and a text file with notes about the archive:
