No, not Revit (thankfully!). But this article is about a cornerstone of the digital architecture promise; digital collaboration and design development.
According to Bloomberg.com, "[Airbus] engineers in Germany and Spain stuck with an earlier version of Paris-based Dassault Systemes' CATIA design software, even though the French and British offices had upgraded to CATIA 5. That meant the German teams couldn't add their design changes for the electrical wiring back into the common three-dimensional digital mockup being produced in Toulouse. ..." ("Airbus Vows Computers Will Speak Same Language After A380 Delay").
Revit, unlike most BIM and CAD applications, is now positioned as a collaboration and digital prototyping tool within the AEC segment, specifically through the offerings of Revit Building (Architecture), Revit Structure (Structural Engineering) and now Revit Systems (Mechanical, Electrical, Plumbing/Hydraulics, Air Handling, Heating and Cooling). In addition to this suite of products, there is the ability to export to gbXML, IFC, and a host of third party applications.
What does this mean for digital collaboration within AEC? The potential is enormous and fantastic. However, the risks, if everyone is not "on the same page" in terms of software versions and capability as highlighted with the Airbus A380 senario, as equally as great.

Stumbled across this gem on Jeffrey McGrew's blog when looking for some info on Revit topography (more on that later).
This tool called Ogle (get it - Open GL - Ogle ...) apparently lets you screen capture 3d information from an Open GL complient application direct from the Open GL video card, and import it into REVIT!!
When I get a moment I will try it out ... but it looks amazing! >>Read more>>
Many users are keen to push Revit to its limits to fully exploit the potential of BIM.
Given the incredible amount of computations that this requires, we are often asked about the "best" hardware spec for Revit.
The minimum system requirements for Revit 9.1 are actually quite manageable, however seeing that in Australia, most Revit seats are purchased as the Series option (share licence with AutoCAD 2007), the minimum (and higher) system spec's of ACAD2007 take precedence.
This is particularly the case with recommended Graphics Cards. Whilst Revit doesn't have a restriction as such, it is HIGHLY recommended that you utilise a certified AutoCAD graphics card to avoid any possible issues (and to future proof your investment.) **
Recently an excellent about this was posted by David Duarte on his blog Revit for Beginners.

Does Revit take full advantage of dual processors?

I am sure that many users have discovered the Autodesk discussion groups whenever they are "googling" for program help, so I thought I would post the link to the discussion directories.
All you could ever want to know and more!
Congratulations and thank you to the tireless work of the moderators and contributors that make the discussion groups happen. I am sure an often thankless but crucial task.

As a technical constultant for a national Autodesk® reseller, I have had the opportunity lately to see a welcome "repositioning" of Autodesk's attitude to the Architecture and Building segment.
Privately, I think this is a "vertical" influence of the success that Autodesk products have had in the engineering and manufacturing segement, where collaboration at the "design" phase of any project is standard - not just desirable.
Therefore, with the recent announcement of products like Impressions®, the adoption of products like Constructware®, FM Desktop®, and the re-investigation of Autodesk products such as Vault® and Buzzsaw®, there is certainly a complete scope of products that can assist all areas of the Architecture and Building industry.

Interesting times indeed ....
Just like layer organisation in good old 'CAD, Project Browser organistation (and naming) becomes critical for any Revit implementation and adoption.
Here is an excellent article on just how (and why) you can control the listing and use of the Project Browser for good, not evil.
"In big Projects, Browzer Organization is an absolute “No Brainer”. It allows you to effectively streamline the otherwise out of control and massive list of views that go with the territory.
The method for Browzer Organization that I have found suites our offices the most effectively is by organizing the views by scale then by associated level. This allows us to work on the parts of the project that are required in that instance of the project time line ..." >>Read more here>>
For those contemplating the move from 2D CAD (Computer Aided Drafting) to 3D CADD (Computer Aided Design and Documentation**), the question I am asked often is how does Revit handle line-weights and pen-widths? The assumption being that default view that Revit uses to display cut and projects of the 3D object can't possibly suit all to the people all of the time.
In my experience, its almost does, but for those amongst you who need the finite control, this posting from L.A.CAD is a great entry to the display (and then printing) variables at your finger tips.
In Revit we may not be aware of the fact that we CAN change the default way the components show up in different views, i.e. Plan, Section, etc. and at different scales ... >> Read more here >>
** Acronyms abound in all industries, but in Architecture and Design, they are absolutely everywhere. From my research, CADD was unfortunately replaced by CAD (which consigned the computer to a drawing board with a screen for almost 20 years.) But now with the advancement in affordable computing power (more so then software), CADD returns again to the fore, joining BIM and a whole new raft of terms.

This is an excellent background article by West Australian (now based in Wales UK) Dr Andrew Marsh, the developer of Ecotect environmental modeling software.
Having worked with Dr Marsh during my tenure at the University of South Australia, and then privately in London with Hamilton Associates UK, it would be hard to find a more dedicated and knowledgeable person in the field of environmental simulations and analysis.
I commend everyone to take some time out and asorb the enormous amount of information on both the Ecotect site, the Squ1 site, and the new site Natural Frequency.
"With an increasing regulatory emphasis on energy efficiency and building performance analysis within the design process, the need for a smooth and hassle-free conversion from CAD tool to analysis engine is becoming critical. This article considers the issues associated with such a transition, looking in detail at the kind of information required by different performance analysis / simulation tools and what is actually available in a typical CAD drawing. It looks at the various options available, including the growing influence of Industry Foundation Classes (IFCs) and gbXML, and what their impacts might be." >>Read more here >>

Cadalyst has discovered that Microsoft’s just-released Internet Explorer 7 is causing problems with Autodesk’s DWF format. Autodesk blogger Steve Shepard reports that DWF Viewer, Design Review and TrueView are not compatible with Microsoft Internet Explorer 7. Uninstalling Internet Explorer 7 and reverting to Internet Explorer 6 does not restore Autodesk functionality, because the supporting libraries from Internet Explorer 7 are left in place. Microsoft does offer a Blocker Toolkit so system administrators can disable automatic delivery of IE 7.
DWF is a full 3D and 2D exhange format that is built into Revit. For more information on DWF, see the excellent Autodesk site for Desgin Review (formally DWF Composer).
Update: Autodesk have released a HOTFIX for this issue which can be found on the "Beyond Paper" blog. Very interesting.
- Improved Material Colors on Compound Structures, such as walls and roofs
- Improved handling of curved surfaces
- Support for Revit 8.1, 9.0 and 9.1
Hopefully the wait is worth it ... as Autodesk has finally released for public download the long-awaiting 9.1 "update" build. 2006_0928_2300.
This build addresses the following issues.
- File inconsistencies stemming from the upgrade process
- Behavior of Rooms with Plan regions
- Improvements in snap to DWG
- Filtering as it relates to the Save-to-Central function
- Unexpected behavior when using the spacebar
- Placing revision tables inside of titleblock families issue
- Irregularities within the Keynote function
- Inconsistencies when upgrading template
- Issues with portable license utility
"Impress colleagues and clients with presentation-ready graphics created directly from your CAD drawings. With Autodesk® Impression, you can add everything from distinct linetypes to textured color fills using prebuilt styles or styles that you create by editing strokes, effects, texture, patterns, and more."
Now the wraps have finally come off the worst kept secret in Autodesk (on purpose probably), I am please to post a link to the public Technology Preview (like a Beta) of Autodesk Impressions® - Autodesk's answer to 2D visualisations and renders, and a pretty good pitch for traditional Adobe Photoshop, Illustrator and Freehand users.
I have been on the Beta developement for this and I am particularly impressed (especially as its a big shift for Autodesk into the vector graphics realm). But so far so good. At one stage Autodesk asks for feedback on some "bylines" for the marketing effort. I am now thinking it should be:
Autodesk Impressions® : Colouring-in for Big Kids!
No, unfortunately there isn't any word on a Revit® Landscape, but the amount of excellent landscape components around suggests it wouldn't be hard to do.
There are 2 excellent resources for additional landscape or planting content, namely RPC (from Archvision) and Bionatics.
Importantly, both services offer Australian content, the RPC pack having a special pack for US$129.
Some RPC content ships with the Revit installation, and has both a cut and projection "symbol" or symbolic block, and a high resolution image map for rendering (with foilage and shadow casting!). Additional packs can be purchased direct from Archvision at www.archvision.com
Bionatics is a French company that specialise in trees and landscape items, through a service called a virtural nursery. The content looks amazing, although they dont list Revit models as such, they are VIZ, ADT and MAX compatible. www.bionatics.com
I'd be keen to hear about other resources that have Australian content.
Discovered more Revit blogs lately, one being dedicated to ability of Revit to export to environmental analysis packages such as Ecotect.
I am hoping to post more about this feature of Revit soon, as there are a huge need for architects to be able to utilise the BIM workflow to include energy ratings, thermal analysis and other building performance data without having to re-input (or model) in stand-alone packages.

Autodesk have recently released Revit 9.1, which is a combination of the 4 build releases and a few new features in the AUSENU default template**
Addiontally, a service pack (SP1) has been released for AutoCAD2007, and a particular one for AutoCAD2007 as part of Revit Series (Revit and AutoCAD 'bundle'.)
Both are available from the link(s) below:
AutoCAD 2007 (Revit Series) Service Pack 1
Revit Building 9.1 Release
**You will note that the default AUSENU template .rte is a whopping 16mb! Yes, its a "oversight" that slipped through according to the Revit developers I emailed. It will revert to the normal 8mb in V10. I will hope to post a revised AUSENU template on the site which has purged the offending component or family file.
Finally able to solve this for a client the other day.
Apparently, in Western Australia, all roofing measurements are given in documentation as Degrees Mintues and Seconds (Do M' S").
You can change your units and measurements settings in Revit to DMS**, but then actually inputting the data seems difficult as there is no 'o' symbol key (or easily memorable shortcut key).
However, in Revit wisdom, if you input the data as 45 45 45 (45o 45' 45") with spaces between the values, Revit will automatically assume the degrees, minutes and the seconds. Easy!!
Yes, it would be nice if this was a little more obvious, and I have made that suggestion direct to the Revit team.
** Revit > Settings > Project Units > Angle > select DMS from the drop down.
While the site looks like it was designed by someones grandchild, it is up to date with the latest REVIT 9 release. A good source of free tutorials which you can view online or download.
Lets hope some graphic style and taste finds its way into the site at some stage.
UPDATED: Well, who would have thought. Daryl, the owner and editor of DG CAD, saw my post and replied to me. OK, so calling the design of his website "crap" is a little harsh in hindsight ... and I have certainly learnt my lesson that nothing you say on the internet is "private". And I cant talk about this site at the moment, as I am "between templates" ... Thanks Daryl, and certainly keep up the great work! m@
Unfortunately not the most orginially named, but a great site for manufacturer content (US centric at the moment). Family files are "hidden" under BIMLibrary > Downloads > and then arranged by manufacturer (sponsor).
Hosts components for all BIM capable packages, like ArchiCAD and Revit (and some AutoCAD DWG's - not that AutoCAD is true BIM).
Lets hope more Australian manufacturers get onboard - or start up a rival site.
Amazing site, with the best family file search tool "Family Explorer" (sounds like a car), and a fantastic collection of links, relevant articles, and tutorials.
Free registration and worth making it a part of your daily Revit roundups!
Great news! BHP (through Bluescope, Lysaghts, Fielders and every other steel manufacturer they now own) supports REVIT by hosting steel profiles, components and material maps in REVIT family format.
Register for free, then use either the flash based CAD Panel, or search for you steel profile using the Advance search and selecting REVIT as your program type. Incredibly comprehensive, and let's hope other manufacturers get the hint and incorporate REVIT in their product resources. Stay tuned.
