Hey Luke. Here a small tool i made to clean op the journal files that revit leaves behind on the computer. It seems it doesn not clean these files out of itselve, and can take up a lot of space on the computer pretty fast. If anyone sees room for improvements they can use the contact button to mail them top me, so i can put it in a next version. As gmail/hotmail wont let me sent a zip with an exe in it (install file) i uploaded it to my site, and can be downloaded here:
More recently (ie. this week), Chris delivered a webcast on the usefulness of IFC for NYC-RUG and gave his permission that it be uploaded to the web. See the whole webcast embedded below:
So here is the breadcrumb of credit– Created by Chris Zoog, uploaded to Dropbox by theoryshaw, put on Youtube by BenPMalone.
In the webcast, Chris talks about (among other things):
history of IFC
using Grasshopper and Geometry Gym plugins with Revit (see my previous posts)
drofus
Generic Model Adaptive Components used in simulation
clash detection / code compliance
Tekla Bimsight / Solibri Model Checker
“Navisworks is ubiquitous but this (Solibri) is the better tool”
BCF – BIM Collaboration format
the IFCExportAs parameter for non-system families in Revit

It is recommended viewing if you are interested in the current uses of IFC and he also hints at what the future may hold…
A summary of the webcast from LinkedIn: Jeffrey Ouellette • Well, he showed several: 1. Design & Documentation – A set of formal parametric design constraints were developed in Rhino using Grasshopper, tagged with IFC data and then exported as IFC files and imported into Revit. The objects were translated into Revit-native data structures (some better than others). The design work would be VERY difficult, if at all possible, in Revit, so he showed that using a design tool built for such purposes could still exchange the model data with the preferred documentation platform, totally different technologies, using IFC. Granted the connection was based on IFC4…. 2. Planning & Design. dRofus is a very powerful web-based, database-centric, planning and facility data management tool. Via IFC exchanges, he showed how owner program requirements, developed most efficiently in dRofus, could be transferred to Revit via IFC2x3. Also designs in Revit could be re-imported into dRofus to compare and verify the model design against the requirements, AUTOMATICALLY! 3. Clash Detection/Coordination. Yes, Revit and Navisworks can talk to each other with a high degree of ease and fidelity now, but he showed how Solibri Model Checker (SMC), an IFC model based BIM tool, can find, report, and share this information in a variety of ways, including sharing model comments between platforms via BCF. 4. Code checking. Using Solibri Model Checker (SMC), a Revit design model is exported via IFC and examined for exiting, occupancy, and critical clearances using logical rules based on code requirements, such as IBC. 5. QA/QC. Beyond just using SMC for code compliance and clash detection, SMC can be used to determine the quality and validity of a BIM, both geometry and data, with rules based on a particular domain or even between domains. What was most impressive was that it was working, given the reputation for Autodesk’s previous interoperability efforts, but noted recent improvements in support. He was able to demonstrate that there was no excuse for being able to use IFC-based workflows TODAY, even with Revit. You just have to learn and do. My old Kendo sensei would always say, “Don’t TRY, just DO”. He wanted us to understand the importance of removing the abstract from the shinai (bamboo sword) being an analogy of a metal blade to moving, behaving, reacting to it BEING a real blade. If you merely try, then you fail and give up because you feel there is no consequence. But, if you act as if your life is on the line, then you will only stumble for a while as you get better. via Which file formats? Struggling to decide… | LinkedIn
Hi @zoog, @nycrug great presentation on #IFC/OpenBIM, ended up recording it 4 U guys. bit.ly/VKplNF Video’s huge though…2gigs. 😐 — Ryan Schultz (@theoryshaw) January 16, 2013
Currently most of the content is focused on AutoCAD and 3DSMax. This initiative is somewhat similar to Mosaic. However, Mosaic does require you to use your Autodesk SSO (single sign on). You can also check out the Revit Wikihelp Twitter feed.
The Autodesk / scoop.it links to watch out for are below:
“service and support tips, tricks, updates, news, and solutions “ Support News Network
At the moment, the content is primarily along the lines of ‘getting started’ and basic modelling. I’m sure it will get more advanced very soon…
I played with Blender back in mid-2008. At the time I was using some of the randomization capability to make some organic forms for ultimate use in Revit. I used a plugin called Blender World Forge (ver 0.1.0). I had some success, but it wasn’t total. Here is an example:
I wanted to share this with you, because it certainly brought a smile to my face: Troy Whitehas sent you a message.

Subject: Thanks for the add.
I have been a devoted follower of your blog for a few years now. Excellent stuff! Your posts have helped me to streamline my workflow, and enhance my understanding of the revit back end. Appreciate all of your work! Thanks again. …
Luke is a true Revit guru. His informative blog “What Revit Wants” is the last stop on my weekly review. As an operator who spends 50-plus living in the Revit-led BIM ecosystem, the importance of understanding the structure and logic of the software is key to developing an agile and efficient workflow. This is what Luke offers, a computational guide to the inner workings of this exceptional and complex program. His results are always interesting, sometimes paradigm shaking, and never lacking in thought. -Troy White, BIM Modeler
Its good to be reminded that the blog is appreciated. Thanks Troy! (you can check his profile on LinkedIn)
PS. I love it that Troy states “understanding the structure and logic of the software is key…” This is the essence and purpose of knowing What Revit Wants and making it work for You.
Some followups from Twitter (also see the Comments):
If a View Template includes a Design Option visibility setting, and then the associated Design Option Set is deleted, Revit will prompt you to delete the View Template:
Obviously, you can untick the box to retain your View Template.
Until we have full multi-core implementation on Revit, it is essentially looking at one core at a time (except for certain uses, such as Rendering). Mark Cronin has tested whether Hyper Threading helps standard Revit – and his benchmarks indicate that it does not… the number to look at below is 318 (no HT) vs 335 (with HT).
He “averaged the results from the workstation, and the scores can be seen below: They clearly show that there is at least a marginal improvement in the model creation portion of the testing, and a substantial performance reduction in the rendering section with Hyper-Threading disabled.” via Hyper-Threading for Revit? | betterREVIT
How far has multi-core implementation come in Revit? Gordon Price on RFO: File and view open are both multi-threaded, as are exporting of DWGs and images. Pretty sure printing is multi-threaded now too. And I am sure that updating a curtain wall is, just not sure yet if that is a function of curtain walls specifically, or if updating any family in a project is multi-threaded. Pretty sure it is not everything, as I just tested changing a wall thickness and it pegged my dual core VM at 50%. Edits to doors hit 49-50% for just a second. I suspect curtain walls got the optimized code because 1: it was easier and 2: really complex curtain walls kill performance
I recall that the revit.ini used to have a setting for multi-core wall join cleanup. Steve mentions it in quoting a Revit technical note: In Revit 2010, multi-threaded methods for printing and wall join cleanup have been made available. Multi-threaded hidden line removal for printing has been enabled by default. via Revit OpEd: Multi Core/Processors – Tech Note
So the revit.ini used to have ParallelWallJoins and ParallelPrintProcessing switches. I’m not sure if these are still implemented in Revit 2013 (my .ini was at “C:UsersLukeAppDataRoamingAutodeskRevitAutodesk Revit 2013Revit.ini” but didn’t include any lines for these multi-core switches … However, it might still be possible to add them.)
