Taking Revit Server "off-road"

Borrowing from the title of a recent post by Mr. Revit OpEd I wanted to bring up what I think is a rather critical point to be aware of if you're thinking of running Revit Server on your laptop to solve what is often termed the "Construction Trailer" problem. I've been in touch with the two sets of folks who I know have installed RS on a Win7 computer, that is Mr. Baldachinno and Mr. Cone (Beck / Aaron Maller). For David its an experiment in "low cost" servers for a small company. For Kelly & Co. its an attempt to make an easier way for users in a construction trailer to work on their Central Files.

What I want to highlight is if you're running RS on your laptop, so you can "work" on your central files live over the Construction Trailer's DSL connection with a VPN tunnel, is that your user(s) need to learn how to shut down Revit Server gracefully. The very clear and present danger here is that a user in the trailer, simply turns their computer off, or worse yet, "pulls the plug". I can guarantee that you're playing with fire here if your users do that. There is a good chance that at some point they'll corrupt some or all of the Revit data cached locally to their  "server". Autodesk has some clear instructions on how to shut down a Revit Server properly, the problem is, that it involves locking the whole infrastructure while you take down whichever local server you're shutting down. The good news here is that there is a much smaller risk to the data on the actual Central Server. It does a good job of protecting itself and the data it is responsible for, so a Local Server suddenly going off-line should* not affect any of the data at the central server.

Just a word of caution for those attempting to push technology to the bleeding edge and not just the cutting edge.

*Note, I say should, there are conceivably instances where the sudden shutdown of the client or the local server might cause harm to the Central Server data store, but theoretically these should be pretty remote. Worst case is that a lock is left in place on the Central Server due to the "user" disconnecting in the middle of an operation. Keep in mind that when a user SWCs data is committed directly to the Central and Local Servers, and the data is not committed to the project data store until the transaction is 100% verified.

AEC Media Day Wrap up and final thoughts

Still waiting for David to post the pic of Phil's slide, but we'll get there....

In any case I wanted to start this post by sending out a big thank you to Autodesk for hosting everyone for 2 days and particularly to my direct contact there and his efforts. Secondly as other bloggers have alluded to Wednesday afternoon we went into the bowels of the factory and met with various folks from the development teams and I want to send out a thank you to them too!

To that end, I think some of my fellow bloggers have alluded to the fact that we don't get to blog about what we talk about with development. With that said, what I can say is never under-estimate the complexity of a problem. As one developer said, let me sit down with one person for a day, to discuss a problem, and we'll have solution to the problem by the end of the day. The problem is, that it will be "Steve's solution to the problem" not Robert's or David's or David's (strangely we had an overwhelming number of Davids around), etc. The point being that particularly as Revit continues to expand its market presence internationally the Factory has to develop tools and features that are flexible enough to meet a variety of needs both in terms of "conveying information, be it 3D or 2D" and ease and intuitiveness of use. Its interesting to hear about the user research that has been done, and to see some of the differences that exist between the United States, Great Britain and Germany, all "western" countries in terms of how we build buildings, how we use tools and how we document the buildings to be built. Things like addressing multiple audiences gets even worse when you consider that contractors are using the tools more and they have their own set of desires, needs and goals.

We all saw what happened with the Ribbon on its first go around, and that was strictly UI development, and in an earlier post I observed that it was great that tagging between links had more functionality, but that 3D tagging suffers the same "almost but not quite" as we saw with link tagging in 2011. Thus I would posit that quite honestly, some of the places where "we" really would like to see increased functionality are quite complex problems and not even from a code development perspective, but from a user's needs, desires and results perspective. Certainly one can make the argument that in some cases some "small" changes would go a long way to satisfying user's needs, but the Factory has most definitely shifted towards taking a longer view (and the executives seem to support this) on feature development, and there is an interest in fully understanding the whole problem and developing solutions that not only meet immediate needs but are building blocks for further development down the road. On top of that, we still have to remember that there are only 24 hours in a day, and Autodesk is a company that needs to make a profit and only has some much money to invest, lastly at least in my experience working on Building Design projects simply throwing more money and more staff at a problem will not necessarily solve that problem any more quickly.

Error Correction: Tagging in 3D Views

I will correct the original post, but I wanted to clarify, all Keynoting Features are available for usin 3D views, including tagging materials by Keynote. I was correct about not being able to tag materials directly, and what I didn't point is that you cannot tag Rooms/Spaces/Areas, but then we can't see them in 3D either.... :-(

Thanks to my friends at Autodesk for pointing out my mistake.

AEC Media Day: Update 8 - What's Phil thinking about...?

Wrapping up with a presentation from Phil Bernstein and a couple of other "industry thinkers" at Autodesk.

What is an architect's role? What are we doing?

• Pre-fabrication, with the Architect involved
• Fewer spreadsheets, more data in the model, with better reporting out of the model
• Using the model to generate "live information" to keep people up-to-date on progress ("live" 4D?)
• Using BIM to really "digitally prototype" the building (same vein as what Peter was talking about yesterday and plenty of others before them).
• Challenge the traditional relationship between O, C & AE so that information flows.

I think the best wrap up on what Phil is thinking about is the pic of the slide (coming David.....?) that David has posted on his blog, we need to "change" along three vectors, and Autodesk thinks that its technology solutions are getting closer to fully helping that change.

AEC Media Day: Update 7 - Trends?

One thing that I'm taking away from Autodesk's message these past one and half days is that the "B" in BIM is/has/will moved away from being a Noun and more towards a Verb (at least that seems to be ADSK's marketing message). I think in some ways this is very true, and is more in-line with the direction many of us would like to see the industry move. That is rather then talking about a Building Information Model, ie an intelligent model of a particular building we seem to be moving to where we want to talk about Building an Information Model. This means we're more focused on developing information rich models to help plan, design and develop the built environment, and starts to encompass far more then the building I'm designing today, but the entire environment in which we live, work and play.

It seems to make sense to me, it will be interesting to see if industry as a whole begins to make this slight philosophical approach to what we've been talking about a number of years now.

AEC Media Day: Update 6 - @ the cusp

The last future's direction presentation is more of "digital cities" (Project Galileo) and tools that allow you to deal with massive datasets to do conceptual planning within a 3D urban environment based on information from a variety of sources, GIS, Lidar, Revit, BIM, CAD, etc.

I feel like Autodesk has been spinning this story for several years now, but I also feel like we're closer then we've ever been. I still think there are going to be a number of issues with gathering the data and getting access to it, so you really can do all the things they propose.

We'll see what the future holds....

AEC Media Day: Update 5 - Looking Forward

Presentation this morning on where Autodesk sees technology going/developing. Just had a really interesting film reel demo of what looked to be a derivative of Autodesk Lab's current Project Neon accessible from Revit. It makes sense, and hopefully this is representative of a tech preview we will see someday in the not to distant future.

They're also doing film reels of pushing Structural and Energy Analysis to the cloud from Structure and MEP so that as you design, your design is constantly being analyzed and re-analyzed. Cool looking stuff, though I think they'll have to be prepared to really answer Engineer's questions about calcs are being done, before they jump on the band wagon.

AEC Media Day: Update 4 - Suffolk Construction

Awesome presentation so far from Peter Campot, President of Suffolk construction. He just put up a labor graph from a project, proving BIM works. They coordinated everything, verified, and started MEP 5 months earlier then usual, and built a building that went together exactly the way the computer said it would, which means their labor usage did exactly what we've all been predicting for years!!

AEC Media Day: Update 3 - Sustainable Design

The "rumor" I just heard from the latest speaker is that Revit 2012 will include the Solar Analysis tool that had previously been an Autodesk Lab's plug-in, and then was rolled into Project Vasari late last year with its release.

Autodesk is also pushing sustainable design and that they have products that match all levels of design. I think the one caveat to that is that the wonderful narrative they just spun relied on several (more then three) tech previews on Autodesk Labs..... I don't know about you, but most companies don't like to use products that have "expiration dates" with no guarantee of renewal on projects that may continue longer then the life of the "product", or at the very least we need to access the data later.

Another important note, Autodesk is re-packaging their software into Suites (similar to Office or Adobe), all well and good, and it will be great for small and medium business. What I think is really, really cool, is that Sketchbook Pro is included in all the suites. Why is this important you ask? Well prior to the 2012 release Sketchbook was always a stand-alone license and if you were in a large network environment that was problematic at best. Now with the suites, if you buy network license versions Sketchbook is part of that network license pool, which is great! Now you can make it available to anyone to play with, use or do whatever they want!

AEC Media Day: Update 2 - BIM 360

So Autodesk has laid out a new imitative that they intend to focus on and provide (or adapt) technology solutions for the AEC space. For Autodesk BIM 360 is focused on providing a robust set of collaboration and coordination tools that help all the stakeholders in a building project share and "see" all the data related to a project and provide a scalable, enterprise quality set of products that are secure and easy to use.

So the cornerstone starting out is Autodesk Vault, adapted for, and integrated with the AEC products (ACAD, Revit, etc). Most importantly the whole thing becomes an umbrella for a variety of technologies with Vault providing the back-bone. So under this "new" product we'll see direct integration of products like Navisworks, Design Review, Buzzsaw, Revit Server, ACAD WS, and Project Bluestreak.

This is particularly important to large enterprise customers (me now...) who need secure, scalable solutions for sharing data internally and with external consultants, that doesn't compromise data integrity. In any case, still light on details, but it all sounds promising, ADSK says a "product" (Vault for AEC) will be available in May, with more details to come.

ADSK Media Day: Revit 2012 - Tagging 3D Views

So, Autodesk was kind enough to invite me again to Media Day. The highlights for me being that I can blog more about 2012, renew aquatenance and connections, and maybe have some side conversations whose content can't be shared. :-)

Today's agenda looks interesting, I'll get to learn some more about this whole "suite" thing and it looks like some interesting outside speakers will be talking about what they've been doing with Autodesk tools.

In any case, chatting last night a topic came to mind about Revit 2012.

Per other bloggers you should already know that you can now "lock" a 3D view to help prevent accidental changes to the point of view such that the view can be placed in a document set and you know it (hopefully) won't change. I say hopefully because someone can still choose to unlock the view and manipulate it. The other really critical part is that you can now create "Tags" in 3D views (note this does not include perspectives) rather then just text. Combined with the lock functionality this allows you to have a consistent "2D" 3D view to put into a document set.

So we're all excited about consistent 3D views we can annotate, right (I know I am)!! The important caveat, at this time, particularly for Architects, is that you cannot use Keynotes in the 3D view and you cannot tag Materials or Rooms/Areas/Spaces (still not visible in 3D). This limitation is a bit disappointing particularly as it brings to mind last year's release where we could tag across links, but could not tag Rooms, Areas, Spaces, Beam Systems & Keynotes. The good news though is that all of that was fixed in this year's release, so hopefully next year the limitations of tagging in 3D views will be addressed. Before grumbling too much about these limitations, I think it is also important to note (or be aware of) the business case that drove this tool into the product. While it is considered a "platform" enhancement much of the dev was driven from the MEP side, particularly because they need "riser diagrams" (yes architects have been asking for tagging in 3D for years, but it was MEP that finally pushed it over the edge). So, in that that light, one can see where Materials and Keynotes took a "back seat" in terms of priority if the major concern is to show significant duct and pipe risers.

Of important note to architects, you may want to see my previous post about a "technique" for creating a camera callout in your plan views (huh, I wonder, why I was so concerned about calling out 3D views in December....).

When you have a hammer, everything is a nail.....

Ok, so not quite true, but one must ask the question, now that '12 supports placing Adaptive Components in project, what are we to do with them?

Well the first answer is, just about anything!!! Remember that AC's can have a single placement point (they don't need multiples) meaning that the family will behave very similar to placing any non-hosted family. I'll let Krista follow-up with a post on this brilliant work-flow, including my suggestion on how to "circumnavigate" the issue of limited category options for AC's.

On to the main subject of this post....

Since time eternal (or at least as long as I can remember) Revit has had a 1D array (ie, define a start point an end point and elements are arrayed between them). However in architecture there are certainly a number of occasions where a 2D array would be far more useful (ie create a "grid" of elements rather then a single row). Now this little technique will not solve all problems, but it may help with some, and inspire others.

My use case is this, we do a number of education facilities at our firm, which means classrooms, classrooms often means regulated "arrays" of chairs or desks, rows and rows of them in fact. So what if we could simple define the outside corners of where we want our furniture, the distance between each row and column, and let the computer do the rest, including dynamically updated if we change the size, interested!?

Enter adaptive components. The first step is to create an AC with a flat plain, that is actually a "void" (thus not visible as a piece of geometry). Each corner (however many you want) is of course an Adaptive Point. Once we have the Void Surface, we can divide it (clever tick huh?) so now we have a grid that we can control with parameters. Did I mention that we can also put the AC into the Furniture Category (kinda useful).



Now that we have our armature, we need some panels to go in our grid. Time for a new family, this time a Panel by Points family (also can be put into the Furniture Category). This family is a little more complicated, you could model your actual furniture here, but my suggestion is to load a family built from the standard template(s). The trick is locating the family in the panel. Here, I've created two sets of crossing reference lines that lock my tablet arm chair to the center of the panel. You could always look at doing an offset, or something else, but for the purposes of demonstration, I decided to keep it "simple".

Once you have your furniture panel, you can load it into your array family. Place the panel (of course you have multiple panels, and allow users to use a Type Parameter to switch one from another) into the divided surface, and now we have a 2D array of chairs. Once that is done, load the array family into your project and start placing.

As with just about anything that uses Adaptive Components, more CPU power is going to be your friend. Regen times can be high with Adaptive Components, though as long as the nested family is not too complex, you should not see anything to far out of the ballpark here.

Lists

One drawback to switching directly from 2010 to 2012 you start using features that were in 2011 that you had forgotten about.

Oh lists, where have you been all my life? :-)

Some downsides to the list text feature is:

1) You can't break text into separate columns and continue the numbering.

2) You can't start a list with anything other then 1., A., or a. What if I want to start my list at 32?

Fun little things you find...

So, I suppose this has been posted on AUGI or blogs and such, but since I'm back to working on projects it is always fun when you find something "interesting". I never knew (until today) that you can't use the line work tool on objects that are contained in a design option. Of course the simple way to deal with this is to make the design option editable, but its still bit odd to me given that the linework tool is effectively a graphic override in the view you're working in.

Something else that I came across that is rather annoying. When you're drawing Drafting Lines, you can change the type of curve you're drawing, ie straight, arc, tangent arc, etc, but you can't change the style you're using, ie Wide Lines, Thin Lines, etc.... Rather annoying when working, but such is life...

Perspective Graphics

So here's a realistic example of where I've used some of the new graphic features in 2012.

We have a revolving panel that can be rotated out of the way. In previous versions if you set the view to realistic you wouldn't be able to see what the space would look like closed unless you move the panels out of the way. But now with 2012 you can.

So you just simply right click on an object & go to Override graphics in view by element:

Then Click on Ghost Surfaces:

And Voila! Ghosted panels that give you and your client an idea of what the space will look like with the panels both open & closed.

When will 2012 arrive?

And when will this new release happen ....

Sometime in mid April.

The gag order is lifted!! Its 2012 Time!

Yep, that time of year again folks a new release is right around the corner! With any luck I'll have some follow-up posts but I'm working a on a project these days as the PA, so that has been keeping me a bit busy! I have to say I would love to get my active project into 2012 for a variety of reasons (most of which are listed below).

While I would not consider this year's release to be a blockuster, its still solid. As has been typical for the last couple of years Architects will mainly benefit from what are considered to be "platform" enhancements (because in reality they're useful to everyone) but I would say are mostly driven by Architecture customers. This year's release I would also say has a bent towards addressing issues that large projects (and therefore mostly large firms) have to deal with. Structural folks who are really interested in the analysis model, and looking for analysis packages to more easily talk to Revit (bi-directionally) should also be jazzed as much of Structure's enhancements revolve around completely rebuilding the analysis engine, for that they have the "Core Modeling" (conceptual massing environment) enhancements from '10 & '11 to thank.

Lastly '12 sees the release of new tool subset (currently only available in Architecture and Structure), we now have version 1 of "Construction Modeling" tools. While targeted as a toolset for contrators or design build shops working in Revit, I think that as these tools develop, they should prove quite useful for architects and engineers too.

Things that excite me about this year's release:

• Tagging Rooms, Spaces & Area across links.
• Tagging Keynotes across links.
• Revamp of "Graphics Display Options" dialog:
• Ambient Shadows print/export.
• Ambient Shadows in Hidden Line (really sweet....).
• Shadows in Consistent Colors (a little odd I know, but in line with traditional colored elevation techniques).
• Ghost Surfaces (the biggest complaint will be no way to adjust the level of ghosting, but still great for diagramtic views).
• Adaptive Components can be placed "in project"*
• Revamp of CAD export dialog, most importantly settings are stored in the project now, so no more custom export files, except to define specific standards to be used for different clients/jobs.
• Construction Modeling**:
• Parts - has great potential for panelized wall systems (a pet interest of mine).
• Assemblies - has lots of potential.
• Introduction of Workplane Viewer to the project environment (still needs some work, but plenty of potential)
• Worksharing Display (visualization of use of worksets):
• Similar to the Temp Hide/Isolate and Reveal Hidden Commands.
• Four modes: Checkout Status, Owners, Model Updates, Worksets
• Revit Server improvements:
• Cache files are cleaned up.
• Permission data is cleaned up.
• Admin console provides more detailed information about SWC's and Model Size versus Data Size.
• Compatible with 2008 R2 and VMware.
• Comprehensive API, including the ability to create new locals files with programming.
• Point Cloud integration: built using Autodesk's existing technology, also "version 1" but a good start and it has full API support, so software vendors specializing in Point Clouds will be able to build Revit Addins that take advantage of their technology and integrate with Revit.

* With great power comes great responsibility... Alas the number of categories that AC's can be in is rather limited, mostly out of concern of potentially "breaking" the software. With any hope that list will increase over the coming years.

** Remember this is version 1 of a whole new toolset. There are most definitely some limitations here but also a huge amount of potential in the long run. I'll be covering "Parts" to some extent in my RTC course this June.

Those are the things that most interest me. MEP as expected continues to see a great deal of development, but at this point I'm just not enough of an engineer to appreciate the improvements. As with any Revit release there are subtle fixes (bug or otherwise), background improvements that you'll never really "see" and plenty of small enhancements and features.

With any luck I'll be following up with a couple of posts on "practice" adaptive components, but alas one is "in  the shop" right now being looked at by the experts as it seems I've managed to break Revit (as usual).

Star Wars

More to come ....

Placeholder Sheets

I was reminded how great the placeholder option is.

I needed to create a drawing schedule but some of the sheets we don't need right now

but will need later. So I created some placeholders (the top three sheets seen below).

Now I need to issue schematic design without those placeholders included so I clicked on Hide and voila:

Now how do I know what sheets I have yet to create? Click on Isolate & tada:

I Love BIM

Kiddos attempt to convince me she can go to work with me:
