In a hour the AU wrap event fires up and ends at 9pm. I then am heading to the airport to catch my 1am flight back home.
Another thing that I did while here was sit for a short radio interview for www.intotomorrow.com, a radio show on technology. It was kinda different for sure but fun as well. This weekend the spot will be broadcast and it will be downloadable very soon. Keep an eye out, I'll post a link to it when it is available. www.graveline.com is probably where it will be put.
A final word from AU. I met a number of people who actually said they read my blog. Frankly I was shocked! Since I don't pay that much to this blog nor the visiter counts I had not idea it was being a source of information much less entertainment. I now feel a little more compelled to put more good stuff here, we shall see. To those that took the time to say hi, thanks!

During this little party I also spent some time with Tom Wier and Jamie Richardson, fellow Mastering Revit Structure authors. We reflected on the book writing this year, the publishing process and our hopes for the book acceptance in the industry. Writing a book is like have a kid - you want it to be good and a success, regardless of making any money! Only the main stream authors write for cash, us tech writers do it for the love of writing and sharing information.
Following the speaker gig, I hit the AEC Bim party. This thing started small just a few years ago and now has hundreds attending. During this event I spent a good deal of time talking to Nicolas Mangon and others with Autodesk. I did so much talking that my voice this morning was a bit scratchy and soar. I think I may need to take it easier today.
Next up today is the keynote, AUGI Volunteer luncheon, followed by a couple classes. Then this evening is the exhibit hall opening. That is always the craziest and most entertaining time for me.
01 December 2008
Anyway, all is set. There are two things to hit this evening; the AU Speaker Social. It's a chance for the staff to meet and greet with the speakers and share a drink or three. Usually a fun time and very low key.
After that is a AEC BIM Mixer - yet another opportunity to meet and greet with the movers and shakers in the A/E/C & BIM industry. After Thanksgiving last week, I feel like a shaker more than a mover. I suspect I will get a chance to meet the cream of the BIM crop at this - and have another beer I suspect.
Tomorrow, classes begin! I hope to keep my blog hot with blurbs from the event. I also noticed it is 1 year now since this little rag was born. It started with a lot of energy but I will admit has foundered a bit on occasion. I pledge to do it right from now on - and post as a good blog parent should!

Well the publisher is going to post it on their web site and when the book gets a second printing, it will be there, but in the meantime it is only fair to offer up any venue I have to get his statement out in the public eye. To that end, below is the Foreward for the Mastering Revit Structure 2009 book.
When I was only 5 or 6 years old, I decided to become a structural engineer like my father. Every weekend, my dad would take me to visit the construction sites he was working on. I enjoyed watching concrete being poured, rebar being bended and installed, and was fascinated by the cranes, formwork, and cement trucks. As a teenager, I got my first computer, and realized the power of programming and its ability to automate tedious work. I had a big dilemma; which career should I choose? Should I pick computer science or structural engineering? I decided to pursue both. My graduation thesis was naturally a mix of computer science and structural engineering. My passion for conceiving how I might be able to blend these two different fields of study led me to develop load distribution software for concrete structures. The software enabled engineers to pre-size concrete structures in a matter of hours, thus being able to evaluate the material quantities of steel and concrete. In realizing how fragmented the industry was in terms of process, roles, responsibilities, and task automation, I then decided that I would spend my career trying to create tools to streamline the design-to-construction process. Over the past 20 years, I have been involved in the design of software for structural engineers, drafters, and fabricators in Europe and North America. I’ve worked on a wide variety of products that cover all areas of the structural industry including structural modeling, structural analysis and design, steel and concrete detailing, and finally design of post tensioned and precast concrete structures.
In April of 2003, one year after Autodesk acquired Revit Corporation, I was hired by the founders of Revit to extend the product beyond simply an architectural based product to a complete structural package based on the same principles. I remember when I used Revit technology for the first time. I was amazed by its parametric approach and the great potential for the structural engineering community. I was very overwhelmed. I thought to myself; how do I get started? What do I include? On the positive side, I was starting with a blank canvas. The challenge for me was that I had no paint or brushes, or even subject! Through my past experiences, I’ve learned that you should never design software for yourself. I also remembered a line from a product management course that I had taken which was simply “your opinion, although interesting, is irrelevant!” Not a very comforting thought, but probably very accurate.
With that in mind, I needed to gather information and input from potential users, industry experts, and engineers. I had to find people that could help me. I found myself chasing structural folks, who were interested in Revit Technology in blogs and forums, when I found Tom Weir from Brandow & Johnston in Los Angeles. I sent him an email to ask for his help. His reply was a resounding, “YES, YES, YES!” He reminded me that he had been in the industry for over 20 years, too! Tom was an early user of AutoCAD V2.6 and Softdesk Structural. He has been a model enthusiast since the beginning. Given Tom’s passion and energy, I jumped on a plane to pay him a visit. We spent quite some time reviewing his process and exploring his ideas. It was the beginning of a fruitful relationship that still continues to this day, and in fact, Tom has been involved in every release of Revit Structure.
A few months later, I was put in touch with Walter P Moore and Associates (WPM). We met to discuss software and technology. At WPM, all roads eventually lead to David Harrington. When it comes to technology, David has extensive experience on model-based technology, and specifically, Architectural Desktop. He is also a power user of AutoCAD. David and I had some very interesting discussions on how to move from an AutoCAD environment to a Revit environment. We still share the same passions and always continue our discussions each time we meet.
In June 2005, we launched the first release of Revit Structure. Even with such a young product, we immediately experienced tremendous interest from the community. I was invited to present BIM vision for structural engineers by Jamie Richardson from Ericksen Roed & Associates, Inc. Shortly thereafter, Jamie started working on multiple projects and rapidly became a Revit Structure expert. Jamie has made significant contributions in the development of the product. Lastly, I am one of the most loyal readers of the content put forth by Eric Wing editor and writer for Revit in AUGI World Magazine. Eric’s creative ideas and desire to take Revit Structure to a higher level for the Structural Engineering community is an inspiration that I am very excited about.
In my opinion, these four authors are a virtual “dream team” of Revit Structure expertise and industry knowledge. They all share the energy, the passion, and even the emotion for Revit Structure. Combined with thousands of users around the world, they play a vital role for the continued success and future enhancement for Revit Structure to make it the best product for the structural engineering community.
With a tighter introduction of analysis in the BIM process, with the new simulation concepts based on analysis, a more complete BIM including more data and details, and with more interoperability between the different disciplines (architects, MEP, fabricators, civil), we see a viral adoption of BIM within the structural community. We also know that we are just beginning a massive industry process change that will streamline the lifecycle of a project from design to construction and maintenance. Very few people have the opportunity to see their industry be transformed so dramatically. These are very exciting times and Tom, David, Jamie, and Eric are active contributors to this phenomenon.
I hope you enjoy this book. I know it will help you to become a more productive user of Revit Structure as it will open your eyes to new technologies and ideas while providing the vital tools necessary to design and build the greatest structures in the world!

I was chatting with Nicolas Mangon at Autodesk and being that he is French asked if had a 3D DWG file of the Eiffel Tower. Well he didn't, at least not at that moment. So he looked around and his fellow Autodesker(coworker) Pawel Piechnik came up with one. Impressionnant! He sent it to me as an AutoCAD DWG file. I ran it through a custom program here at WPM and stupéfier! A Revit Structure model of the Eiffel Tower!
Now, for sure the model is not complete. There are lots of little pieces not modeled. But what this does show is that there really isn't a project that can't be modeled if you want it bad enough.
I was going to post the files here but they really are too large for this blog. But if you want a copy, just drop me an email at dharrington(at)walterpmoore.com.

Ten Things You Might Not Know About Working in Revit Structure
1. Structural Slab Properties: One of the instance properties of a slab is for it to be a structural slab. This is the default setting but can be set to be non-structural. If a slab’s layer function is set to display Structural Deck and its properties is set to be a Structural Slab, the flutes or profile of the deck will be visible in section views that are set to medium or fine detail levels. A slab with these characteristics can be copied into Revit Architecture which will take on the properties of a Structural Slab, thus displaying the flutes of the deck. This allows both structure and architecture to take advantage of the deck profile display.
2. Edit Structure Assembly Dialog: The bottom of slabs can be set to be flat while the top surface slopes. This can be done by setting the layer of the slab that is to be flat to be “Variable” in the Edit Structure Assembly dialog. The overall thickness must be as thick as the distance from the highest point of the top surface to the bottom of the slab.
3. Pressing the Spacebar: Pressing the spacebar while placing elements such as Structural Walls and Structural Columns will flip the wall about its location line or rotate the column about its insertion point prior to placing it in its final location. Pressing the spacebar after these elements are placed will perform similar behavior.
4. Selecting the Appropriate View: Dimension the outside face of an HSS Tube Steel member cannot be done when the view is set to a fine detail level. To place these dimensions, first set the view to a medium view, place the dimension by selecting the outside faces of the member, then set the view back to the fine detail level.
5. Callouts: Callouts can be placed to reference other views the same way Sections can be placed by selecting “Reference other view” from the Options bar prior to placing the Section or Callout. Callouts are a bit different in that views must be set to crop the view in order for them to display in the Reference other view pull down. If views are not showing up, check this setting.
6. Options Bar: When selecting the sketch lines while editing a slab shape, the Options bar displays additional information for adjusting the steel and concrete cantilever distance. Adjusting these settings allows for the steel deck to pull back from the concrete slab edge in a composite slab scenario.
7. Span Direction Tag: Rotating the direction of steel deck in a slab can only be done by using a Span Direction tag. If the slab is not tagged with a Span Direction, you must do so prior to rotating the steel deck direction. Once a Span Direction tag is in place the deck can be rotated by rotating the tag or by selecting the tag and choosing “Align Perpendicular” from the Options bar. Select the edge of slab to align the deck.
8. Breaking Stacked Walls: Stacked walls can be broken up into Basic walls by selecting them and right-clicking to select “Break up”.
9. Splitting Walls Horizontally: Walls can also be split horizontally. In a 3D or section view select “Split” from the Tool bar. Select the location for the wall to be split. When using this tool, the wall automatically creates a lock which locks the walls together vertically and horizontally. If one wall moves they will all move.
10. Reference Planes: Reference planes can be placed to attach elements to or used to cut elements by using the element attachment tools or the cut geometry tools on the Tool bars. After the reference planes are placed, it is recommended you give them a name so they are not mistakenly deleted. If they are deleted, the attachments or cut relationship to the elements are lost.

Also while at AU, Wiley publishing is hosting the Mastering Revit Structure 2009 book authors in their booth at various times. Want to say hi? That might be the best way to find me. Another to option is the AUGI Booth. If I'm in the exhibit hall and not at Wiley's, I'll be over at the AUGI Booth hanging with the members. ;)

I think this internal class was my 9th conducted. So far so good.

I do feel that way - I have so ignored this thing it is pathetic! Anyway, I'm setting a reminder to myself to post more often so we shall see.
So what is new? Well the Mastering Revit Structure 2009 book is done in writing and off in production with expected street date late in November. You check it out at Wiley's web site for the book here. It came out really good IMHO, I hope it gets a great reception in the industry.
AUGIWorld is offline for the moment. AUGI and SolidVapor are producing an issue for AU (Nov/Dec08) but after that is unknown. I've done technical editing for AUGIWorld for quite some time so I will miss it but no doubt find something new to do.
Workwise I have a number of projects underway, most notably a new baseball stadium with a retractable roof. Doing a large roof like this in Revit is interesting to say the least! Also, back in August Walter P Moore opened an office in San Francisco and Washington DC. So literally, WPM, spans coast to coast now.

This week I go to Houston and then I hope to take a break for a month at least. I have to begin planning for AU 2008, get my flight and write my paper for the Standards class I am teaching.
I also at the end of August I finally moved into a 'new' home. It was a short sale - wow, what an aggravation that was. Anyway, so I have lots on my 'Honey do' list - especially with all my recent travel taking me out of the house!

However, I just sent off the editorial content for the July/August issue and it looks to be a killer edition. We have articles on Impression, AutoCAD, AutoCAD Architecture, Inventor, and Revit Architecture.
As always, if you are interested in writing for AUGIWorld, or Hot News for that matter, just contact me and see where you can get plugged in!

Now as for my thoughts on this topic, there are a few methods out there and if you go down that road you need to run some tests. You need to know if your structure type #1) can support itself with whatever material you are using, and #2) can support other things as well. Both of these issues should be paired with the size of the members you are modeling. If your incoming member is thinnly walled the shape itself will have trouble keeping its strength.
Until these systems can actually do metal, one has to embellish the shapes to get them to work. Therein lies the rub, if you fake it to make it work - does it still have value as model?

Passover (Hebrew, Yiddish: פֶּסַח, Pesach, Tiberian: pɛsaħ, Israeli: Pesah, Pesakh) is a Jewish and Samaritan holy day and festival commemorating the Exodus from Egypt and the liberation of the Israelites from slavery. It is also known as Festival of the Unleavened Bread (חַג הַמַּצּוֹת, ħaɣ ham:asʕ:oθ, "Chag/Khag Hamatzot/s").
Passover begins on the 15th day of the month of Nisan (19.April.2008), the first month of the Hebrew calendar, in accordance with the Hebrew Bible. The Exodus of the Jews from Egypt took place in the spring and so Passover must be celebrated in the spring.

I know, a little cheesy, but to a long time user a new release is like getting a birthday present. I've got my prep work still to do - upgrading my menu to the new ribbon interface. Then there is the sorting through dozens of PC3 and CTB/STB files used on old projects and don't need to be carried to 09.
Okay, now it don't sound as fun anymore... ;)

You should note the overall directory structure coming from S: drive, \Content is all from Autodesk whereas ...2008\Imperial Library is my structure. Let me know if you need more clarification.
06 March 2008
To continue, what I have done to handle this issue is two part:
Family Files: I assign a unique naming convention to all custom or revisied family files. For my firm we choose a '#' prefix for all files we created or changed. If I am modeling away the time and see a family file in my model without a # sign prefix, then I know we didn't make it. If by chance I see the same family name with a # sign prefix, then I know I need to use that one instead. As an added benefit family files prefixed with a # sign will be listed at the top of their section in the Project Browser.
Directories: I also name all directories with a # sign prefix, telling the user that this directory is the company default structure. All families files/directories are stored on the server as well. On the server we also have all out-of-the-box content (under \Content of course) but in another main directory area. That content is not under the default directories users place in their Options File Search paths.
For example, you need to load a Detail Component. You fire up the Load dialog and you will be presented with all Firm family files. More than likely that is what you want, but on occasion we have not provided our own. In that directory will be a shortcut link to the same structure under \Content. The user can then click the link and will be in the out-of-the-box location.
I know this seems confusing so I will try to break it down again. There are 2 directory structures, A & B. A has the same organization but only contains Firm family files. B is out of the box. Within the A structure are shortcut links to the same structure location in B. The user's Options are all pointed to A directory structures.
That is the essence. If you don't understand it let me know and I'll post a pic of the layout.

However, I am very busy. On my plate at the moment is doing some training internally at Walter P Moore. I hacked up a 12 hour RST basics class for engineers and have given it once. It went pretty well and I'm looking to repeat it again at the end of the month.
Also coming is preparing for the next version of AutoCAD. We have a custom menuing system at WPM and I need to rework for our new AutoCAD GUI enhancements.
Anyway, I have more to chat about but need to unplug for the evening. I promise to offer a better blogging effort - I just need to give myself a daily task in Outlook!

Gone are hassles with downloading a bunch of little apps, now one download and install will get you everything they have to offer. If you have not tried the extensions (and you use RST), you should give them a whirl. I especially like the Grid and Level Generator.

Joe Fiorello asked if there was a way to turn off Press + Drag feature in Revit Structure 2008. After a little review of the Revit.ini file I found a toggle that should turn it off at application start.

Designed to mimic the look of a trash can, TEMPO is a unique hard drive storage device. Intended to protect the user from accidentally deleting files, it can also be used as an external storage device. As you delete files, they are automatically copied to the *TEMPO. As it fills up, led's light the "can" from the bottom up, informing you of how much space is available.*Tempo is just a concept. It hasn't been technologically designed.
