It has always surprised me how low the number of interior design teams using Revit has been – often even not used by interiors teams in large firms where the majority of the architecture projects are being delivered using Revit. For me, Revit has always offered significant benefits to my projects, ever since I made the decision my team would move away from 2D CAD packages and into Revit for all projects back in 2007. That’s right -all projects. I doesn’t matter how big or how small a project, or if there are existing drawings in a 2D CAD format, or even if my new design team doesn’t yet know Revit – all the projects I have lead and worked on for the last 7 years have been primarily designed and documented in Revit. Recently, I’ve been pleased to find more interest in using Revit for interior design with a number of people mentioning to me both in person and on twitter that they want to know more about the benefits of Revit for interiors. So I thought it might be time to write a blog post (which has turned into 2 parts) on the main benefits of using Revit, as well as tips for optimising Revit for interior design teams. Today’s post is focussed more on the information benefits and setup of Revit whilst the next part will discuss Revit as a design and visulisation tool.
The Power of Scheduling
When asked recently on twitter for my number one tip for using Revit for interiors, it was to make use of scheduling. From the very beginning of using Revit it was the scheduling and tagging abilities of Revit that have paid off for my projects. At its most basic, the use of schedules for room areas or workstation numbers saves time every time. Scheduling furniture, fixtures and signage is also a breeze – and even better visually now that Revit 2015 allows us to incorporate images – finally! I am sure this change will play a big part in convincing interior designers to use Revit. Door schedules are great too – although come with their own challenges, as do finishes schedules (material take off in Revit terminology).
Anything you used to schedule in word or excel, you can schedule in Revit, so why type everything twice and risk making mistakes? There are a couple of key issues to be aware of when using Revit for schedules. Firstly you have to remember that your schedule is based on your model – if there is garbage in your model (eg two chairs on top of one another, or chairs off in space), there will be garbage in your schedule. The other is the visibility filters set in the schedule, what is not visible is not counted. If the schedule name is Level 23 Workstation Schedule, but the schedule filter is set to Level 22 then its not of much use (just as if someone accidentally counted off the wrong plan!). Schedules always need to be manually checked when first set up, and then some ongoing common sense checking as the project progresses.
Schedules themselves are also great to help you with checking. I use various kinds of schedules for BCA and GreenStar calculations and checking and even expanded schedules to check filtered or totaled schedules. Taken further schedules can become the basis for Room Data sheets created in excel, word (or other 3d party softwares). For an example using excel you can see my previous post What’s in a Room?
If you are interested in more on Revit Scheduling I have presentation on slide share called Informedesign which is primarily about using Revit and its information (often conveyed via schedules) to support your design process.
At the end of the day, the value of scheduling lies in its ability to free up time to spend more time doing what we love – designing. But before we get to the benefits of Revit in the design process, I will touch on the other key aspect of freeing up your time in Revit – leveraging repaatative content.
Revit loves repetition
Its true, Revit loves repetition. Many people believe that means its not valuable for the one off – but it is and I am going to talk more about that next post. However, as with scheduling you use Revit’s power of repetition to free up your time to focus on the one off items and area, because that is where we should focus our efforts as designers.
Two areas of Revit are key for repetition, families and groups. Families are discussed further below as part of your libraries but groups should also form part of your strategy for repetition. I’ve written extensively before about groups – so once you have got the basics of this post, you can go read more about groups here.
Building your generic library
Interior designers and BIM managers alike are often dismayed by the thought of modeling everything in an interior design project (or even worse – by starting to think about what could go into a every project), every piece of furniture and every material known to man. The answer to this dilemma – is that you don’t necessarily have to. If its your first Revit project and your aim isn’t to deliver a full BIM project then don’t try to – you will overwhelm yourself and struggle to deliver. Start off with a little and build up over time. Focus initially on two areas, one is the more generic content and the other is the areas where Revit assists your design thinking.
By generic content, I mean the components you use most frequently in projects. This will differ depending upon your firm, the types of projects you do and the types of 3d imagery you need to output. For me, primarily I am designing workplace and educational projects. My basic set of generic content therefore includes task seating, a few different lounge, meeting and cafe seating styles and a couple of shapes and styles of tables with easy to modify sizes and bases. At its most basic joinery and equipment may start out as a family that just contains a box.
Focus on your outputs. If all you are producing is 1:100 test fit planning – you are wasting time modeling every cupboard and agonising over what each chair looks like. As long as you have your plan objects looking right, you can produce your deliverables (and schedule too). Over time you can start to develop your 3D detail or information for different areas over time depending upon your design stages and outputs. For example, while we will end up modeling the casework in a store room eventually (in order to document it), we probably won’t look at it in anything other than plan until quite late in the project (or you might never even need to). By contrast, the 3D development of key spaces such as reception will begin much earlier and may include more specific furniture, joinery and finishes even from the very first presentations. Workstation areas would be likely to be in between. We model almost everything in 3D, so we can create massing type images and flythroughs, it is then the level of detail that differs across the objects in different areas. This also helps to contribute to a more sketchy feel earlier in the design process (as do the new 2015 sketchy lines).
I would also say, don’t rule out using supplier content but don’t rely on it exclusively. For anything you are going to use over and over again, you can start from a supplier family but make sure you do some sort of QA to determine if its suitable for your ways of using it – for me key things are that it is the right way around (all Hermans Millers chairs are backwards) and that is has a 3d plan component to it so it will represent as white in views with colour schedules applied. Beyond that I may also go further with replacing parameters and materials if my uses for it require this. (eg for scheduling) Its great to see the range of furniture and fixtures available as Revit families are growing – examples currently available include Haworth, Steelcase, Caroma and Britex (you can find a good starting list here at IGS website).
The other key part of your generic content is materials. It much more efficient to have a library and templates that already contain basic finishes such as white powedercoat, black laminate or stainless steel complete with information and keynotes that then doesn’t need to be recreated in every project. Again supplier sources such as Dulux free Colour Atlas for Revit app or RTV’s Revit Paint (which includes Dulux, Resene and more) can also help build up your material options quickly.
Next post I will talk more about Revit materials and finishes as well as how to use Revit to power your interior design process, but also about some of the limitations of Revit for interiors (Autodesk hope you will be reading!). In the meantime, are you using Revit for interior design? What are your tips? Or is your firm starting to think about it? What makes you hesitate? Are you just starting out with Revit for interiors? What’s driving you batty? (because Revit does do that too, even to me some days!)
