Revit and Reinforcement


Structural rebars in beam

I had the great pleasure of presenting Revit Reinforcement problems, solutions, features and workflows at the Revit Technology Conference Australasia 2014 in Melbourne Australia last week. As always on these conferences I get to meet so many interesting and smart people who share my passion for 3D digital building design, but this time something was slightly different. This time I met surprisingly many who was already familiar with parts of my work on Reinforcement and Adaptive Components. That was a bit new to me, and something that makes me immensely proud. To realize that people on the other side of the planet use your research is indescribably motivating.


Changes since previous Rebar presentations

The presentation I did was basically the same brain dump curriculum that I did at AU 2012, RTCNA 2013 and AU 2013, although this time modified with updates for Revit 2015 (there are a few important ones) and removal of the sections on complex modeling (double-curved concrete walls and post-tension reinforcement). I decided to remove the last parts mainly because I’ve done little progress on the Adaptive Component research lately, and also feel these families have some performance issues when used on multiple and large repeaters.


Rebar Set Symbolic Representation

To me, there are two big new features in Revit 2015 when it comes to reinforcement: Symbolic Representation of Rebar Sets and Rebar Number. As I said during my presentation, these features seem to work really well, and especially the representation tools look good with last year’s Multi-Rebar Annotation families. Hat tips there to Pawel Piechnik and his team at Autodesk for implementing important features that are easy to use, fast and well implemented.

The presentation I did at AU 2013 received amazing reviews, something I naturally was rather pleased with. Here is a selection, with ratings from 1 to 10:

  • Quality of the class materials: 9.44
  • Overall Class Satisfaction: 9.24
  • Speaker’s level of preparation: 9.56
  • Quality of the technical content: 9.38
  • Speaker’s knowledge of the subject: 9.47
  • Speaker’s ability to present and communicate: 9.41

The RTCAUS 2014 presentation was also well received, but feedback forms are not yet complete.

Revit Technology Conference North America 2013

PT project-1

In July I had the great privilege and pleasure of both attending and presenting at the inaugural Revit Technology Conference (RTC) North America, held in Vancouver Canada. This was my first ever RTC, and being invited to speak was very humbling and exciting.

Meeting funny people from all over the world who have the same passion as me for 3D digital design is truly one of the most rewarding aspects of the kind of work I do.

Thankfully, this was only the first of several social events this year, as I will be present at both RTC Europe in Delft and Autodesk University in Las Vegas. I’m also of course looking very much forward to this year’s Revit Gunslinger event in Waltham, MA.

The presentation I did at RTCNA was about 3D reinforcement modeling in Revit. It was an updated and enhanced version of the same session I did at AU 2012. Specifically I added a section on complex rebar modeling, exemplified with Adaptive Components for post tension tendon modeling. This example is mostly “for fun”, as I’m still not too sure how well these families work with regards to detailing, documenting and fabrication.

In case you’re interested in checking out the class material, here’s the PowerPoint. my Rebar Manifesto and over 80MB of delicious rebar dataset:

The rebar dataset includes a sample project (courtesy of Rambøll), my presentation demo project file, Rebar Shape RFA’s, a selection of exported models (IFC, NWC, IPB and DWFX), post-tension families (Adaptive Components) and some data-files (Shared Parameters and IFC Export mapping text file).

I would humbly guess the Rebar Shape families could provide useful for structural engineers, at least across northern Europe.
