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.

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).

News!! AU & more!

So we've been quiet for quite some time, because there are just sooo many things going in our lives!!!

First off, I will be presenting at AU this year. Two Classes, One Lab and one Virtual Session. Thankfully I have a great supporting cast around me, and each is only an hour long:

• Parametrics Laid Bare: Panels and Adaptive Components in Autodesk Revit: AB223-1
• Beyond Project Templates: Managing Company Standards and Best Practices in Autodesk Revit: AB234-4P
• Au Bon Panel: Baking Your Own Adaptive Components and Panels with Autodesk Revit Architecture: AB316-1L
• "Virtually" There: Using Revit with Geographically Dispersed Teams: AB22-1R

Hopefully Krista will be co-speaking (via Skype) with me for the Project Templates course, but alas, she may be a little tied up with our new baby who is due on Nov. 13th!!


Lastly, if you have not heard or seen the most recent big news, you may want to read the press release here.


Look for some more posts later this month, but I suspect we will continue to run pretty silent, stay tuned!

Revit 2011: Stepped Foundations with Adaptive Components

So, if you want to learn all sorts of impractical for the new Adaptive Components (AC) you can visit Builz. But if you're interested in some more practical applications you've come to the correct place.

I don't know about you, but I've always found modeling stepped footings to be a bit of a pain. There were several techniques, but they all had their drawbacks. I think the newest technique that AC's offer us is the best yet. It is still not perfect, but its quick and easy! This quick demo illustrates some of the flexibility AC's actually offer, and the concept of thinking of the Conceptual Mass Environment as a wrapper for working with these elements.
