RTC North America 2012! Oh & Revit 2013

So the veil has lifted for yet another year on the latest release of Revit. I know that David Light will provide a detailed overview of the new features so I'll spare you re-writing my own post. That said I'm very excited by the changes to View Templates and View Types, I view this as critical to help maintain a graphically consistent document set in your model, particularly when working on large projects with big teams. The other big piece that I think many architecture users will get excited about will be the new stair tool (the old one is still there) and some minor improvements in railings. Would we like more, perhaps, but at least we've got something, rather than nothing.

So, the other thing I've been tardy on letting people know about is that Krista, David and myself are all schedule to be speaking at RTC '12 about Stairs and Rails! Of course up until now my class brief on the RTC website had to be intentionally vague, but now I can let everyone know that the course will not be discussing the old stairs and railing tools, but will focus on the enhancements provided by 2013.

So if you have not already, seriously consider signing up for RTC, if last year's is any indication, this year should be fantastic, particularly with a larger audience!

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).

Guide Grids

I’ve been exploring these a little bit as we get ready to roll out 2011 to the firm. I have to say they are an odd mix of Revit objects and attributes. For instance;

How do you delete a guide grid?

Well oddly enough, to detele a Guide Grid from a project, you simply select it, and delete it! If you have multiple Guide Grids defined you cannot purge them, and they don’t show up in the project browser. They simply exist in the sheet view(s). What is even odder is what this behavior implies. A guide grid is effectively an instance of a datum object similar to Grids, Levels or Reference Planes. There are no type properties of a Guide Grids, there is a single “Type” within a whole project. When you manipulate the Instance Properties of a particular Guide Grid in the Properties Pallette, it updates the Grid in all the sheets you’ve “placed” the grid in. In fact what you’ve really done is actually make that particular instance of the Type Guide grid visible in the particular sheets you assigned it to. You don’t actually place the Grid. What this also means is that the location of any particular grid is based on the origin of a sheet view.

Interestingly enough, if you get to thinking about it, Sheet Views are really nothing more then a Drafting View whose behavior has been specialized to allow Views of the Model to be added to them. They have an origin just like drafting views, but “we” can never see or find that origin perse (its important to note that using the API you can find the origin in both Drafting and Sheet Views, or using a linked DWG).

The point is, that the Guide Grid function operates based on the premise that your titleblock locations share a common origin, much as Grids operate on the premise that your model is built around a commong origin from floor to floor. If you move your titleblock (for whatever reason) within the Sheet View Canvas, the Guide Grid will be in the same place, but not relative to the Titleblock.

What this also means is that even though the Guide Grid uses a very basic implentation of the “Pattern” functionality to create the graphical grid, it effectively represents the coordinate system of the Sheet View(s) with the one minor fact that you don’t know where 0,0 is.

What really gets me about this whole thing is, why implement each individual grid as a separate instance of a single Type? Why not allow multiple Types to be defined? Multiple Types would make more sense in the long run, and would allow for some type of “management” console to see all the defined type at once, and delete/modify, etc. Instead all we get is a drop down in view properties, which in reality is simply turning the visibility of a particular instance on or off. Furthermore, when you click on the “Guide Grid” button once again you’re creating “new” by way of placing a new element of an existing Type. Lastly, this comes back to the “delete” issue. In Revit “delete” can be and sometimes is confused with “removal”. One can easily imagine a user opting to “delete” a grid from a particular view, when in fact they simply want to make it no longer visible in that one view. Hitting delete however may have the un-desired effect of completely removing the Guide Grid from the whole project (which might be a big problem!).

I have to say, the one really nice thing about the functionality they did add, is that if, like us, you’ve added your own “grid” and visibility controls to your Titleblock families (with Symbolic Lines) then you can actually use that to snap to and align your views (or offset them from the grid to a specific point, etc.). What is nice about this approach is that the grid is relative to the Titleblock, so if you move the Titleblock, or for some reason delete it, then add a new one back later, you will always have the “same” grid no matter what.

For now, even though there are some drawbacks in terms of management and printing with our own TB grids, I think I’ll generally stick with them, as it seems to have fewer pitfalls, and is potentially less confusing in the long run, then Guide Grids.

Subtle Updates in 2011

We'll get back to Media Day, but for now Steve does a good job of recapping most of what went on etc.

First up on updates in 2011, everything that was previously only available for Subscription customers (Q3 Subscription Advantage Pack) is available to everyone who buys Revit, needless to say, Autodesk's sales pitch is, "buy the subscription pack it will be worth it" (something confirmed at the Media Day and recent Boston Revit User group events).

So what about these subtle changes?

The first one quite handy, "Save View as Image", You can right click on any view in the project browser and choose "Save View as Image". This is a great way to "freeze" a drawing, without having to export to CAD, and it keeps everything in the model. The same functionality is also exposed in the API. One presumes that this is all part of the new "Analysis Styles" view framework meant to make it easier to graphically convey and save analysis data in the model.



Next, we have some changes in the user interface. Autocad users can rejoice, Revit's UI now supports activating  a modifier command (such as Copy, Rotate or Move) before selecting any elements. Once the command is activated, you can select elements, finish the selection and execute the command. This means that combined with more keyboard shortcuts, mouse clicks to the ribbon can be greatly decreased.



Lastly, Revit Structure provides a number of enhancements to framing, particulary in terms of cleaning up slanted columns, trusses, and how you can place edit these elements. All these changes are available in Architecture too. I have to say I think the method of placing a slanted column is quite elegant (not the only one either) and the new ability to manipulate the top and bottom of a column is quite handy to.

Autodesk: AEC Media Day, Revit 2011 Text & Labels

Well, technically media day is tomorrow, but it started tonight with a reception. Quite the crowd they've brought in, and I appreciated being invited and entertained too. Steve Stafford, David Light David Harrington, Lachmi Khemlani and more were all there.

Tomorrow we get down to all the "real" release info, a chance to ask questions, and perhaps, if we're lucky some goodies that we probably won't be allowed to blog about anyway (pesky NDAs....).

Text & Labels

A small, but possibly overlooked new feature in 2011 is a change to Text and Labels (you may have already heard Text is going to support bullets, numbering and several other new features).  What I want to focus on in this post is the new border feature.

In both text and label types you can check to show a border around the text in the object. The size of the border is controlled by the size of the text/label box and the offset in the type properties. I tend to equate the offset to being the "margin" around the text, but since this offset also controls where a leader terminates, I guess they've used the correct term.

Of course, this means you better start thinking about redoing all your tags and annotations! Think of all those families with boxes draw with symbolic lines, that don't adapt to text size! No longer a problem, with the border feature. Line weight of the line is controlled by way of the Text/Label type properties. However, its important to note that the box and any associated leaders will have the same line-weight. It also means that the line-weight will be consistent in all views. The only way to override the line weight is an object specific override. It would be preferable possibly useful if the leader and border had their own subcategories, under annotation categories, but perhaps next year..... On second thought, perhaps it should remain a type property? Or possibly, both? Allow the base value to be defined in Object Styles, overrides in Visual Styles, and then, last a property in Type Properties that has "By Category" by default.

Subscription Advantage Pack available

Sometime in the last 24 hours Autodesk posted the new Build, Revit Extensions, Model Review (aka BIM Review) and DB connect on the subscription website. Enjoy!

Follow-up from Revit Blogger Day

First, no, I'm not getting paid (though I keep hearing "the check is in the mail"....) ;-)

To dive into a little more detail Autodesk will be releasing the "Subscription Advantage Pack" essentially this wraps up things like "Revit Extensions" or the brand new "Wood Framing Utility" as well as including a special Revit build that includes new features for subscribers only. This new build and any new features will of course be compatible with non-subscribers, however those of us who work for companies that do subscribe will now get tools such as what was listed previously.

So what's coming, I think my previous list of new "features" was pretty self explanatory. What else is coming...

For Revit Arch & Structure there will be a new extension for wood framing. What this does, is it allows you to select you walls (yes walls only) and generate wood framing following various rules, you can adjust the framing in an editor. When you're done, push the magic button and you get wood 2x's modeled all over your model... pretty sweet (almost makes me want to do plain old residential construction).

The Revit DB link (which had previously been posted on Autodesk Labs (with a built in timebomb) will now be available.

"Model Review" this looks like Avatech's BIM Review, but more tightly integrated with Revit, I know there is a very close relationship there, so to say "I'm not suprsised" is not to much of an overstatement. Part of Autodesk's plug with the new Model Review extension is that it will allow you to validate a model is ready for energy anaylsis, and help to identify what needs to be fixed in order to get valid results.

There is a bunch of feature ports in the custom build. For instance; architects will be able to:

• Create Sloped Columns
• Create Curved Beams
• Create complex Trusses
• Cope beams
• Create slabs with integrated metal decking profiles and slab direction

The "split wall with gap" tool has moved out of the realm of an INI mod, into a real feature. Autodesk can't say much about overall performance of this tool, other then that is has been in use for awhile. What is nice is that when used, it maintains the wall as a single object, even though it has been split. It seems like this tool has some useful possibilities, but I'm not totally sold, yet....

Structure is getting some improvements to the bridge tool. MEP is getting all new content particularly for electrical stuff besides Power & Lighting. MEP is also going to get tempory dimensions when in layout mode (which should prove useful).

You'll find other folks blogging about this new stuff, so be sure to see what I missed, or get their take.
