What's new in Autodesk Revit 2013?

The year is 2012 & the Autodesk fanfare announces the arrival of Revit 2013. The Revit technology has now been under Autodesk ownership for just over 10 years. Wow! How the world has changed in that time, politically & economically. 10 years ago I would have never believed that Revit would have had such an impact on my career. Back then the original Revit vision was a one stop shop solution for all AEC disciplines. Whilst the tools for structure were less developed than those for architecture, certainly I was aware of engineers who were using Revit. I once heard a blasphemous rumour that a MEP tool set was being developed for Revit, but to this day, can’t confirm or deny that was the case. Either way, Revit was seen as a holistic solution that would serve the AEC industry. Nether the less Autodesk saw things differently & divided the product up into the 3 flavours that we know as Architecture, Structure & MEP. But Autodesk have been under pressure from the industry to look at the way Revit is served up. BIM by its nature is a collaborative effort & many multi dis firms are using all flavours of the product. Also, other firms want to use architectural tools in say an MEP workflow. The industry has spoken, there should be no BIM silos, so Mr Autodesk, give us the Revit product which includes all the disciplines!

Revit 2013 will come in its now well established traditional flavours of Architecture, Structure & MEP. But it will also come as a complete AEC solution, code named “OneBox” during development, this will be all three disciplines installed as one. The official name will just be Revit 2013. In Revit 2013 you have access to all of the platform tools and if you need to, you can customize the ribbon interface to turn off the discipline tools you don’t require. This can be done via the options dialogue box under User Interface.

Certain changes have been made to some tools to allow consistency across the different disciplines. For instance, the ability to save & load selection selects is now available in Architecture & MEP, not just structure. Site tools are made available to the MEP user. The naming & locations of commands now provides a level of consistency. You will also discover that this extends to the filtering of categories. In all products the “show categories from all disciplines” checkbox has been replaced with industry specific list of disciplines. This ensures you have more control over the disciplines you are working on.

 

What’s new?

So what else does Revit 2013 have to offer? This review will focus on the Revit platform enhancements as well are main architectural functionality; I will leave structure & MEP toolsets to others who are far more capable in providing an in-depth review than me! So as well as Onebox we have specific improvements to:-

• View & view templates
• DGN v8 import & export
• DWF & DWG tweaks
• IFC
• Materials
• Further Construction modelling enhancements
• Worksharing
• General usability improvements
• Massing – repeating & dividing
• Visualisation & Graphics
• Stairs & railings

 

Get a view

I have always been a big aficionado of view templates; to be honest I am probably guilty for not using them enough. But for view consistency they are great. However, they had a minor flaw & it seems to catch users out all the time. If you applied a view template to a view, one assumed if you made a change to that template it got automatically applied & updated. Wrong; you had manually reapply the view template. Fortunately the improvements in 2013 ensure that if a view template is updated it does indeed automatically update the view. If a view is controlled by a view template, then it is locked to the template, so then only way to make changes is via the properties embedded within the view templates management dialogue. The old school functionality of applying template properties to a view is still possible, so you have the best of both worlds.

The view template improvements also extend to the ability to associate a view template with view types. This means every time you create a view or duplicate a view it can automatically have a view template associated to it.

Other VT tweaks included allow you to explicitly control which discipline your views are on during creation; plumbing is now an option for a view discipline in its own right; the underlay orientation parameter can be configured in a VT; colour schemes parameters can be assigned to views templates where applicable and when you create a reflected ceiling plan if the underlay orientation is not defined then it will be set to “reflected ceiling by default”.

Whilst not exactly a view template related improvement, more so a work around, but within the worksets dialogue box there is now a project standards workset for workset global visibility settings. It’s a really a hack & is not an answer to proper access & standards control, but in essence, if this workset is owned by one person, others will be unable to change the global visibility setting for any workset. I still believe this is area where Revit falls short, some sort of wider management of standards really does need to be implemented going forward. But for the short term, beggars can’t be choosers & this does provide a fix to an outstanding problem.

 

Collaborating with Microstation

Revit has always been good at collaborating with other “CAD” packages. It has the ability to import & export various versions of DWG & DXF. It is also able to import & export Microstaion files. However, during the 10 years of ownership, plenty of effort has gone into improvement of DWG & DXF capability but the Microstation export & import capabilities have remained stagnant during that time. So it is pleasing to see that Revit 2013 finally gets V8 Microstation support. A new user interface has been provided; mapping functionality for Levels, Lines, Line Weights, Patterns and Text & Fonts has been added to the export DGN workflow; the DGN export settings are retained & saved in the project file. Therefore, if you need to pass these between projects, this can be achieved by using Transfer Project Standards. With regards to importing Microstation files, there is full support for V8 files; minor tweaks have been made to the V7 algorithm & there is added support for importing of design model.

 

Collaborating with AutoCAD

A release of Revit wouldn’t be complete without some work on the DWG Export & Import capabilities! Minor tweaks have been made to the Export CAD formats user interface for DWG/DXF/ SAT/DWF, also views & sheets are now displayed in alphabetical order when the dialog box is launched. There is a wealth of improvements with regards to Export & Import, some which are long overdue. Let’s start with Exporting:-

• Finally! Revit Text elements are now assigned to a text style when exported. This will make it easier to edit multiple text objects at the same time in AutoCAD.
• Images in DWG files exported from Revit no longer report an unreferenced error for the image path in AutoCAD.
• The export of custom hatch patterns has been improved. E.g. export of custom hatch patterns inside walls (e.g. fire lines) will now be exported with the correct hatch pattern scale.
• Export of underlined text elements from Revit has been improved.
• Improved DWG export of filled regions.
• Transparency value set on a Revit element is exported as an AutoCAD property on the object.
• Options for hiding scope boxes, reference planes, and unreferenced view tags have been added to the General tab.

With regards to Importing:

• Improved DWG import of inserted blocks.
• DWG files using “Center to Center” positioning will now be imported center to center of the view on the X, Y plane.

So I am going to leave best improvement on importing to last. So how many times have you imported a CAD file into Revit & seen the message “lines slightly off axis”? It is such a pain, as these errors almost propagate like virus & often end up as embedded errors in your model. They can be time consuming to chase down & rectify. In Revit 2013 we can fix this when importing CAD files. A new tick box option is provided on the import dialog called “Correct lines that are slightly off axis”. So during importing of a CAD file, if the option is ticked, Revit will automatically correct lines that are slightly off axis (less than 0.1 degree).

 

DWF Export Improvements

I am genuinely sold on DWF! Its light weight, quick & retains the embedded model data. With Design Review mobile now appearing on the Ipad as well as Android devices, I hope DWF has a healthy future. But I do wonder, as it seems to continue to have a head to head battle with Navisworks. Although they do compliment themselves well, with Navis being able to link DWF files into its environment. Improvements to DWF in Revit 2013 mean that phasing information is exported in the DWF format & you can manually name multiple views / sheets when you export as a single DWF file.

 

IFC interoperability

IFC short for Industry Foundation Classes, the answer to interoperability or just a pipe dream? So I have to be honest with you, I have a love hate relationship with IFC! It’s a great idea, but in the case of Autodesk, I’m going to kick them hard, their implementation of IFC has been poor. Even round tripping from Revit to IFC back to Revit produces total nonsense! But in Revit 2013 I am encouraged by the amount of work which has taken place to improve IFC import & export. My understanding is that there were some limitations within the code & these have been remedied & over time will allow Autodesk to adopt IFC4 compatibility. Listed below are “some” of obvious the IFC export enhancements in 2013 if you are interested & these are straight from Autodesk development team:-

• 2D Plan view export no longer offset from 3D Geometry
• True North will always be exported to the IFC file, even if True North is the same as Project North.
• Beams never extruded upwards
• Better Geometry splitting for elements allows for fewer surface models
• Floors, Railings, and Room geometry exported as solids or surfaces (not extrusions) will have a coarser geometry than default.
• Doors with nested openings export opening
• Assemblies will now export as IfcElementAssembly,
• IFC export will no longer silently fail when a filename with multi-byte characters (e.g. Chinese characters) is used.
• If any of the PSet_BuildingCommon parameters are in the Project Information, we will export the standard IFC property set "PSet_BuildingCommon".
• Export Parts - If "Current View Only" export is chosen, and the view has Parts visibility on, then parts will be exported instead of the original element geometry.
• Export Uniformat information as IfcClassification and IfcClassificationReference
• General optimizations to reduce IFC export file size
• Better GSA support
• Light Source no longer exported for lighting fixtures
• MEP Plumbing Fixtures exported as IfcFlowTerminal
• Slab base quantities are only exported for COBIE or QTO

On the Import front, some the of the improvements include:-

• Better wall joins
• Different representations have their own elements and sub-categories
• IFC import now properly handles faces that are almost planar.
• More materials imported
• IFC import now does more checks to ensure that illegal faces do not get created on import.
• Space geometry not imported as in-place family solid
• Text Font now set correctly

 

Material changes

Over the last couple of releases of Revit we have seen materials dialogue box continually change. Much under the bonnet work has been taking place & last year you saw some of these results in 2012. Revit 2013 moves this forward. A new Materials data model has been incorporated which includes extended asset data within the material definition. So as well as the appearance, you are able to include structural and thermal performance properties. This extends the capabilities of material for more than just rendering; the thermal performance properties will open up opportunities to performance building energy analysis based on material definitions. The Structural properties data will mean this can be utilized for faster structural analysis calculations. I have to say that I personally found the general UI improvements rather confusing, a lot of picking & clicking & opening of windows which makes the workflow baffling. I guess I will work it out over time.

 

Construction Modelling “the next step”

Revit 2012 introduced us to the notion of Parts & Assembles for construction modelling. The tools represented the process of being able to take a consultants model, then being able to slice & dice it up as a model which is useful for construction. 2013 builds on that initial functionality. You are now able to merge Parts, so if you break two or more Parts, you can merge them into a single element.

You can now specifically exclude Parts from a project. The exclude Part is not visible & will not be scheduled in Parts schedules or component lists. These excluded Parts can be restored at any time by pre-highlighting the Part & using the restore controls from the Ribbon.

The shape handle functionality has been expanded. If a Part is selected, you now get shape handle controls on all faces of the element; just select the reset shape from the Ribbon if you need to reset the Part back to its original form.

Assembly views have also undergone some changes. When creating an Assembly view, you will find additional views available, enabling you to create detail section assembly views from around the Assembly.

The restrictions in 2012 that related to Assembly views & sheets have been lifted. You can now place Assembly views on non-assembly sheets; also Assembly sheets are able to host non-assembly views. This opens up the opportunity for Parts & Assembly to play a significant role where you need to do IPD related construction information or where a designer might need to generate fabrication detailing during CD stage.

All Assemblies how have an origin which is visible in the Edit Assembly Mode. The origin displays as a “point” similar to that available within the conceptual massing tools. This origin points defines the default orientation of the assembly views & also is the centroid that is used if you decide to swap assembly types.

If you divide Parts by drawing sketch line or using intersecting reference planes, in the properties you now choose to add a divider gap value. This allows you to generate parametric gaps on the parts you have created. I can see this being really useful for creating quick & dirty concrete paneling on facades, where you don’t necessarily want to use face based families.

Finally, the feature I have had most fun with is the ability to add a custom profile to divided Parts. A new type of family profile called Division Profile has been introduced that is comprised of a single curve chain that works with the previously mentioned Divider gap parameter. This allows you to generate complex joint conditions; for instance the types you might typically get on pre-cast concrete panels. Previously I was hacking Curtain Panels to achieve this, but I like this new functionality much more.

Each profile can be configured using the properties dialog. The Edge Match parameter defines how to relate the profile relative to the gap distance. There are three possible options; complementary keeps the profiles parallel to one another, mirrored will mirror the division & rotated creates a mirrored & rotated condition.

 

Worksharing

Last year we saw a major overhaul to worksharing, certainly these improvements have helped with the “large team” workflows but there were a few features which didn’t make the shipping version, however they are now included in 2013. When an Edit Request Notification appears, if you move your cursor over the request, this highlights the corresponding elements. A nice touch is the ability to click in an Editing Request Notification as this now enables the Editing Request Dialog. The Editing Request Notifications now provide Grant & Deny buttons for granting or denying an editing request, so you no longer have to bring up the Edit Request dialog to act on a notification request. Additionally, deleted & new elements in the central file are now shown in the Editing Request Notification.

 

General productivity improvements

A release of Revit wouldn’t be complete without general productivity improvements. These enhancements can make all the difference to day to day productivity, there are numerous, but I will pick up the ones which I feel are most compelling. If you have a multi-segment dimension & you decide that you want to remove a particular dimension in the string, you can now tab to the dimension & hit the delete key & the dimension is removed from the string.

It’s funny, but for a heavy weight package such as Revit, there was no diameter dimension tool! 2013 now includes that functionality.

If you equalize a dimension string, you can now to set up dimension parameter to display the dimension in a number of ways, so as well as having value & text you cans also Equality Formula String.

If you do a lot of panning & zooming, then you are genuinely going to appreciate the ability to double click the middle wheel mouse button to invoke a zoom to fit! Another really splendid feature is the ability to search the project browser! About “bloody time”, I have wasted endless hours scrolling up & down the PB on complex mega projects looking for a particular view which I know exist, but I can’t find. The search function works similar to the find function in Microsoft Word, you enter the text for the view you are looking for, and there is a next & previous button to allow you to search through the matches. Your match is highlighted in the PB & the PB will even scroll if required to display the match.

 

Divide & Conquer

I think most Revit users are now comfortable with the conceptual massing tools & the in-place mass functionality in Revit’s project environment. However, whilst it opens up opportunities to build complex forms & surfaces it still lacks certain functions. Have you ever noticed you cannot array in the massing environment? Revit 2013 breaks that limitation by including a divide path tool. This allows the users to divide a range of curves such as lines, arc, ellipses, partial ellipses, Bezier splines, Hermite splines as well as chain curves & edges of forms. All you need to do to divide a path, is select the curve, edge or form you want to divide, invoke the Divide Path tool from the Ribbon & the path is divided, placing a series of node points along the path. The path can be divided by Distance between divisions, Number of divisions, Max or Min distance or you can divide by intersects. Once a path is divided, a number is position by the path, which defines the number of divisions. This number can be clicked in canvas & edited so that you can alter the number of divisions. As you would expect you can assign the division number to a parameter to drive the number of divisions.

So dividing with a series points/nodes is all well & good, but can you place families or elements at each node location? Well the answer to that is to use an Adaptive Component. If you divide your line, then create a Simple Generic model Adaptive Component family. Next load the AC into the divided line family & you can then place the AC on a node of the divided line. There is a new Repeat button; this allows you repeat the AC on all the nodes along the divided path. It couldn’t be simpler.

There are various ways you can place the AC’s so you can miss or even mix up different AC’s types to create different configurations for AC’s on the nodes. As well as using single point AC’s, you can also use multi point AC’s on multiple hosted curves, edges & even divided surfaces.

Again, the principles is as before, but this time draw two lines & divide these. Create a 2 point AC, load this into the divided line family & place the AC onto the nodes in the two divided lines. Hit Repeat & voila! I have played extensively with this feature, looking at all sorts of weird & wonderful options, even ones which I thought it might fail on, but it works a treat. What is not yet possible is to have a scale parameter, so as the AC is repeated along a line it can reduce or increased in size by a known value.

 

 

Architectural big ticket items - visualization

So far if you have managed to wade your way through this review of new Revit 2013 functionality, hopeful you found some useful improvements which will assist when using Revit. However, what about some real barn storming functionality? Ok, let’s start with visualization graphics. Whilst visualization graphics may be low hanging fruit to some BIM purists, to architects & designers a like, it is visualization functionality & the way you present your scheme that helps sell it. I know plenty of people who seemed to enjoy the class that Jason Grant & I gave at AU2011 on presentation graphics, so presentation graphics must be important to some people. In 2013 the Ghost Surfaces & Transparent Override options have been replaced with a single Surface Transparency slider. The Transparency slider allows you to control surfaces between 0 & 100%, so you can control individual elements with different levels of transparency.

Anti-Aliasing can be applied to all views, not just 3d views. If you use RPC content, these will preview correctly in Realistic Visual Style Views. The Graphic Display Option dialog has been further enhanced. You can now choose to between a new Sky background style, Images as background as well as the now famed Gradients backgrounds. You can choose a custom ground colour for the new Sky background, but the Sky colour itself is fixed, also it should be noted that the Sky background can is a little heavy for real-time use but ideal for presentation graphics. Finally we can also use Sky, images, and gradients in elevations, sections, isometrics & perspectives, so no more having to import bitmaps into these views to create sky backgrounds!

If you use Realistic Visual Styles in 3d isometric or perspectives views, you can now specify artificial lights & Photographic Exposure lighting schemes, exactly the same way you do in the mental ray renderer. Performance is slow, but for presentation graphics where you don’t want to render the image using mental ray, it’s a praiseworthy improvement.

A new progressive real-time ray trace render style has been introduced. You enable this new style from the view control bar. As soon as you enable it, the Revit caches the model; the view then starts to render immediately as a photorealistic style. You are able still able to pan & zoom around the Revit model, allowing you to create interactive walk through, but be aware that this renderer is using the processor & not the GPU of the graphics card, so the better your processor, the quicker the viewport will render. The rendering quality starts at low quality, but the longer you leave it the better the quality of the image. You are able to set the lighting, exposure & background from the graphic options dialogue. Once you have reach the quality image you require, you can stop the rendering by either clicking in the view or stopping render from the interactive Ray trace panel. You are able to save views that have been rendered, but be aware that these are only at screen resolution. I am confused why Autodesk thought we needed Ray trace viewport rendering when we have Mental Ray & cloud rendering. Seems rather over kill to me; I would have preferred the effort to have been focused on giving us sketchy graphic styles similar to that product that sounds like a well-known red source product.

 

Architectural big ticket items – stairs & railings

Revit Stairs & Railings…..where do you start! On the whole they are great, but those that are new to Revit soon realize there are some obvious shortcomings when using Stairs & Railings. Not that they are a complete failure, the sketch based process works well & is more aligned with how you typically draft a stair, but granular control is not easy & the way stairs displayed on screen does not always match with local graphic conventions. However, if you have ever read or watched Phil Reads AU class on stairs & railings you realize once mastered, you could hack your way through to create even the most complex stair design using the standard tools available. But for the rest of us, we just want a stair component which just works as we expect to see it. Therefore, to help the “modelling” challenged, Revit 2013 introduces a new stair tool which is component-based rather than sketch based.

The new stairs allows you to assemble a stair using run, landing & support components. Each of these components can be individually modified using grab handles, so the changes can be made in canvas. The improved tools allow you to configure component based stairs in multiply configurations.

The process seems very reminiscent of how you develop stairs in AutoCAD Architecture, the move away from a sketch based approached is certainly alien to me. But the more you play with the functionality the more you recognize that this is genuine move in the right direction. For instance I am most pleased to see that I can now create a 3 run stair or switch back stair. In the past you had to either wrap the sketch on itself, which causes genuine downstream editing issues or you had to create two separate stairs. As the stair is a proper 3d component, this opens up far more flexibility in its configuration, so the new stairs also allow you to customize the end to suit different concrete stair conditions.

The other challenge with stairs has been how they graphically appear as well as how you dimension & annotate them. I have lost count how many hours I have wasted arguing / discussing with architects & project managers why Revit displays stairs how they do. But it’s difficult to defend the in defensible. So these new stairs are far more customizable from a graphics perspective, although the number of sub-categories used to define a stair is confusing. I know that Autodesk has done a lot of user research in this area, as I have provided feedback on the way we like to see stair cases displayed here in the UK. Annotation improvements mean we can annotate individual stair run, landing, and support components. We can now tag the tread depth; treads & risers can be numbered using a Stair Tread / Riser Number tag & we can now properly dimension stairs.

As stairs have moved to component based approach Revit 2013, so are railings. This is not yet complete, there is still much work to do, but the direction is promising. In Revit 2013 there are new handrail and top rail sub-category elements, improved railing transitions, and the ability to include system generated extensions to top rails and handrails. Getting access to the hand rail is very confusing; you need to tab select to get access to the handrail before you edit it. It certainly isn’t very discoverable.

The stair & railing is an on-going multi-year project, so what you see in Revit 2013 is the first incarnation. So if you still yearn for the sketch based stair tools, they are still included. Also, you can convert a component based stair to a sketch based stair for more finite editing, but be aware once you do this; you are not able to convert the sketch back to a component. This is annoying, but as long as you are aware its fine.

 

Conclusion

So there you are, the major improvements for Revit 2013. Am I happy? I think so, but sometimes my expectations are greater than what is delivered. Nether the less Revit 2013 does deliver genuine user productivity benefits. Slowly but surely each release of Revit sees improvements in primary functionality.

If I am truthful, there are aspects of Revit development which have managed to keep up with the pace of industry BIM developments. The Assembly & Parts tools are a case in point, but there are others tools for whatever reason are lagging behind & are starting to show their age. My hope is Autodesk recognise this & address these short comings. The lack of development in the site tools is unbelievably irritating.

One other major concern I have is that often functionality is released which on the face of it seems only partially complete. The staircase improvements are a good example of this. Whilst the new stair tool addresses some specific requirements, which is pleasing to see, in others areas it falls short. Why is this a concern? It relates to training. You now have to train two methods for creating a stair. This can be confusing to the new user & equally frustrating to the Revit expert. The number of hidden dialogue boxed & parameter settings you need to fight your way to customise a stair is truly amazing. It’s certainly not discoverable & goes against everything I believe Revit should be. It may not be a big deal for some, but as I have said many times, moving people to a BIM centric workflow is about changing hearts & minds. I don’t see why the experts have to continually justify why some tools are not finished or why there are two different ways to create the same element. I understand things take time to develop & there are only so many man hours during a yearly development cycle, but a maybe a modular approach could be the answer to ensure things get to a better completed state? It’s a careful balancing act between providing value to the existing client base and ensuring continued dominance and further growth of the Revit platform.

BIM is no longer a pipe dream or something for the earlier adopters or technologists; therefore we need a suite of tools that can deliver at all levels. I do feel that after 10 years, Revit 2013 is going back to its original roots as a solution for the AEC industry.

The wait is almost over

The blogosphere will go mad tomorrow as Autodesk will reveal all the new 2013 products, including Revit 2013.

Dear NDA Violator,

Dear NDA Violator,

My headache has now gone & I have had time to reflect on your actions. I read with interest your justification; No, let me rephrase that, worm turning to explain why you did what you did. Apologies sir, but that just don’t hold water where I come from!

At the end of the day you suggest you are not under any NDA, are not reseller or beta tester. But the fact is you did have access to confidential information & I have a good idea how you acquired the “said” data. I wonder if you still have access to the “said” vendors reseller portals? Hmmmmm makes me wonder. So armed with this information did you ever think of contacting the “said” software vendor to see if you were allowed to post it?...... I guess not. Oh yeah, you are a journalist & you can do what you like. Freedom of speech & all that.

SO I note you see this as some kind of competition? Who gets the most traffic? Really? Oh, did I touch a raw nerve? I guess I did. Do I post for notoriety & want to be the first one past the post? No, I really don’t. If you take a look at my site you will notice only one advert & that’s for my friends & colleagues book. So there you have it, it’s not about revenue generation or being first past the line. I wonder if you can say the same thing???……..Yeah, that’s what I thought.

So that is my response to our Bog post & in my eyes this puts closure to this sorry state of affairs. Normal service is now resumed.

Yours respectfully

David Light :-)

My headache (under NDA)

I generally try to not rant on my blog, it makes you look unprofessional & does you no favours in my humble opinion. However, today is different. I have a headache & it hasn’t gone away ALL day & to add to that, somebody has irritated me & I suspect they have irritated somebody bigger than me. What they have done somehow seems to have ruined it for everybody else. You know who you are! Not sure what sort of power trip you are on, but it’s not cool if I am honest.

When a company puts in place an NDA, (non-disclosure agreement) they put it in for good reason. I have signed more NDA’s than I care to remember. In fact I am thinking of getting one tattooed on my arm. Nether the less, this particular blog pushed out information which is indeed still under NDA to the masses. Why, I really don’t know. They gave some lame bullS**T excuse about they are a journalist exercising their rights as a writer, really? If they are a journalist, that makes me the pope.

Yeah so you wanna be first every year, whoopie do, anyone can grab a load of screen grabs & stuff them on a website & say look at me, ain’t I great. So this numpty has let the cat out of the bag. All I can say is look for quality posts in the next week or so on your favourite product, from your favourite bloggers which hopefully gives you a candid view on what is good & what is not.

So if I have offended the “said” person, sadly I care little, because as I said at the start, I have had a headache & I still have it now.

Launch of NationalBIMLibrary.com

So it really has been a week for BIM content announcements! This is great to see & I am excited to see BIM moving forward in the UK. It seems to have taken a long time for this topic to become a priority. When I first started using Revit, that was 2002, many firms were really not talking about BIM back then. In many cases it was more about generating a model for documentation, scheduling & visualisation, nothing more, nothing less. Times have changed & people are now recognising BIM is about data not just pretty visuals. So after his ecobuild presentation, I managed to speak with Stephen Hamil from NBS about the launch of the nationalBIMlibrary.com.

DL – Why have NBS decided to launch this initiative around BIM?

SH – At NBS/RIBA Enterprises our mission is to be the leading providers of information to the UK construction industry. Through our specification products we already provide structured and maintained data for generic specification, proprietary specification, technical guidance and the latest standards and regulations. This can be thought of a national information model. What has been missing from our information model to date is the geometry. Now that object-orientated CAD packages support true information and not just 3D geometry then this is a natural step for us.

DL – The inevitable question will be, how much content do you have in the NationalBIMLibrary.com?

SH – Our launch set of content is around 200 pre-defined constructions covering external walls, partitions, cladding, ceilings, roofs, floors, windows and doors. These have all been created for UK construction industry custom and practice – for use on jobs in the UK or those abroad to British Standards. The launch set contains concept objects and also rich detailed objects – with full information for construction and FM. We are currently around half way through the next set of content which will be another 200-300 pre-defined objects covering sanitary ware, floor finishes, cubicles, hard landscaping and signage.

In terms of work flow, what we are missing are proprietary objects. But through our RIBA Insight sales force we are now securing contracts with the leading manufacturers. We are going to be pretty flat out over the next few months delivering this, but throughout 2012 we’ll see some of the leading manufacturers appear within the site. The user will then be able to take a concept object, work through its design, then toggle this to the manufacturer object to specify for a tender package or record in an as-built package.

DL – As you know, the discussion about standard is a real hot topic right now, what are your feelings on open standards?

SH – They are critical. But standards should ideally be set based on what the majority of the industry are doing. With BIM, the majority of the industry is not there yet. So there is a danger that standards are set and this limits innovation. A balance must be achieved here and the only answer to this is through collaboration.

At NBS, our chief exec Richard Waterhouse is part of the B/555 committee working on the BS 8541 standards. Our Head of Content Development John Gelder is one of the leaders on the changes to uniclass through CPIC. We are members of buildingSMART and also on the buildingSMART data dictionary team.

Now if we take IFC for example, our feeling with NationalBIMLibrary.com was to take a pragmatic look at this. IFC defines international ISO agreed property sets including COBie, so we’ve used all of these in our objects. In terms of authoring layered objects such as floors and walls we have worked with BIM Academy to create a process that uses an IFC source file and then generates native files in multiple native BIM formats such as Revit and Tekla and ArchiCAD. However, we don’t think it is strong enough yet to create functionally parametric objects such as windows and doors at source – so we don’t argue that it’s the answer to everyone’s problems just yet.

I am quite surprised at the amount of IFC bashing that goes on. Especially considering its basic use, this is as an open record format (like COBie). Back in the late 1990s people didn’t criticise HTML4 when it didn’t work in Netscape like it did in Internet Explorer and Opera. The “customers” strongly told the software vendors (Microsoft and co) that this wasn’t acceptable – they demanded change. When the customers say they are not happy then companies react to this – and now due to open standards, all websites can look great whether viewed in Internet Explorer, Safari, Firefox or Chrome. The same needs to happen in the BIM community world-wide.

That said, I think things are changing and the software vendors are listening. We’ve done some fantastic work with the likes of BIM Academy, BSRIA, AEC3 and Autodesk on a recent TSB funded project around IFC. There are also some very interesting developments coming from Tekla, Graphisoft and Vectorworks around the openBIM movement. At NBS we are members of the BIM Technologies Alliance, the technology group supporting the UK government’s BIM strategy – I am confident that real progress can be made through open standards through collaboration.

DL – Is there room for more than one national library of BIM components?

SH – What I think the government strategy does very well is to concentrate on specifying requirements and then to let the UK construction industries innovate. As the major construction spender in the UK this is a fantastic way to get competition amongst the private sector – whether this with architecture, construction, software applications or information delivery. So I think competition is going to be great for UK construction and we’ll see many providers of BIM content such as BIMStore.co.uk who have also recently featured on this blog.

Before ecobuild started I was speaking with the guys from BIMStore.co.uk and we wished each other all the best. Later in the week I sat and watched Rob’s presentation on the http://www.spacehus.co.uk/ and it was fantastic – true use of BIM in action giving cost certainty in creating low carbon buildings. Afterwards I think it was mentioned that there would be nobody left in Newcastle that week with BIM Academy, 4Projects and kykloud all down presenting at BIM at ecobuild.

When asked who will benefit most from BIM (designer/contractor/client)? I wonder whether it will actually be National Rail?

DL – And what are the plans for the development of NationalBIMLibrary.com?

SH – We’ll be listening to user feedback and asking what they want. After the next set of generic content goes live and the manufacturer content is coming through then we can create more new architectural/landscape content – or look at more configurations of our launch set – or concentrate more on components for the structural, services or infrastructure side of BIM. We’d be happy to take any steers from readers of your blog or the linkedin group we have.

Finally, it’s not all about high quality technical content – but also about clever software. NBS customers can expect to see better linkage and coordination between the specification model and the geometric model coming soon. Also I think our TSB funded research project shows that there are more exciting things on the way with respect to linking the BIM objects through to financial and environmental cost databases. We have a team of people now dedicated to this project, we strongly believe that BIM is the future.

Barbour Product Search and bimstore join forces to promote BIM content

I got some exciting news from the James & Adam at http://www.bimstore.co.uk/. They have teamed up with Barbour Product Search www.barbourproductsearch.info to give specifiers and manufacturer’s access to the latest Building Information Modelling technology.

As we all know you can’t have missed the buzz surrounding BIM, and as interest grows, manufacturers and specifiers are faced with the challenge of adapting their working processes to meet the demands of BIM-savvy clients.

With over 10 year’s experience, bimstore has emerged as the leading online library for BIM content in the UK, helping manufacturers in the creation and hosting of BIM content, including the quick and cost-effective conversion of existing CAD objects to BIM format.

As the market leading digital resource for the entire specification chain Barbour Product Search is the perfect platform to promote bimstore’s extensive library. Specifiers will be able to search for and view BIM content from manufacturers, as well as access a dedicated BIM product library.

I managed to catch up with James & Adam at bimstore recently to better understand this new partnership as well as some of the exciting tools that they are working on.

DL - Hi guys tell me more about this new partnership with Barbour?

JA / AW - We have formed a partnership with Barbour search to power BIM components on their product selector site.  We have built a load of API’s into bimstore to enable this type of functionality.  Not only will bimstore be powering BIM on the Barbour site, we are also working closely with Barbour to help get product manufactures products into BIM, and training the whole of the Barbour team.  Initially the Barbour site will contain BIM on each manufactures product pages and also a dedicated BIM search page.

DL - Until recently you only seem to focus on Revit Content, have you plans to expand to other BIM platforms? Because as we all know, BIM is a collaborative effort…

JA / AW - We recognized this & as of Tuesday 20th March 2011 bimstore will officially support all the major BIM applications, including Revit, Archicad, and Bentley. We believe that quality, parametric; data rich native objects are the best BIM components, rather than a platform neutral IFC object. However, we are still proposing to offer IFC content as a download option. Although these components will not be available for download, on Tuesday we are announcing the fact that we intend to, so that the BIM community can help shape the standards for the content.

DL - So have you had to make changes to bimstore to allow you to expand to the next level?

JA / AW - For sure, we launched phase 1 of bimstore in April 2011. The intention of phase 1 was to get a user base of designers (Revit only) to use the site and we have now reached a critical mass so we are ready for phase 2. Phase 2 will allow us to connect with manufactures to allow them to host there BIM content. To do this we have re-designed the site and its message and adding an Eco-system of other applications and features.

DL - So you mentioned an Eco-system for bimstore, can you explain more?

JA / AW – bimstore is more than just a website, it is a powerful engine that is powering BIM components across the internet. We provide a number of distribution channels that we call the eco-system. All these channels are powered from our central cloud location, keeping all the stats and analytics in one place and enabling easy updating and management.

DL - So by the sounds of it you are working on other tools which will allow users to connect to the BIM Content?

JA / AW - Yes, that’s right. The bimstore Website is the shop window for the BIM components. But we also have a bimstore App, which will you to get direct access to bimstore components directly from within the designers/specifiers chosen software package.

The Revit version will be available for download in the bimstore Labs on the 3rd April 2012. We also have something called bimstore Shelf – When speaking with manufactures, we realised that they wanted to host there BIM components on their own website as well as bimstore. We created bimstore Shelf to solve this problem.  It’s a branded micro site portal that links directly into the manufactures website.

DL - From recent discussions Contractors are recognizing the BIM requirement, are you planning to help them?

JA / AW - We have designed something we are calling the Contractors Portal. Contractors are quickly embracing BIM, and are starting to ask their supply chain for BIM components for their products. bimstore powers Contractor BIM Portals where they can organise and distribute their approved BIM components to design teams.

DL - Looks like you guys having been working hard over the last 12 months, finally any other juicy projects you can share with the readers?

JA / AW - Yep, we are working on a bimstore iPhone & Android App, self explanatory to be honest, but it’s the bimstore site in an app.  Instead of downloading the component, pointless on a mobile! It forwards the BIM component to your email. 

We are also working on something called bimspec, can’t talk too much about this now, but it’s a 100% BIM and completely new type of specification tool. We will be able share more in the future.

DL – Thanks for your time guys & I look forward to seeing the http://www.bimstore.co.uk/ develop as BIM starts to hit critical mass in the UK & beyond.
