BILT EUR 2018: Computational Thinking In Infrastructure Projects: Why, What And How

Ok, so as formerly stated, this blog isn't the most updated as of lately. I stay hopeful that it will change at some time in the future. Sonner rather than later. In the mean time feel free to download my handout and files from this years BILT EUR event in Ljubljana.

Handout: https://www.dropbox.com/s/x2po7u2zhnoanh3/S3.2_HANDOUT_V1_jostein%2C%20olsen_Computational%20Thinking%20in%20Infra.pdf?dl=0

Datasets: https://www.dropbox.com/s/0pczr35zpnhap4f/Material.zip?dl=0

Feel free to use whatever! Thanks also to all the people that I met and to all the great sessions at the conference. BILT is fantastic.

Dynamo and FME: We Need To Go Deeper

FME is a integration plattform for translation of data from a HUGE number of sources. Look at this list of compatible readers and writers: https://www.safe.com/fme/formats-matrix/#!

Safe software which makes FME has recently developed a addin for Dynamo as well, where you can read geometry and data using FME's .NET api.

Quick setup:
1. You must have Dynamo for Revit, version 1.3.2 or newer
2. FME 2018.0 or newer must be installed and licensed.
3. Install the ImportFromFME package from the package manager

The way it works:
1. Navigate to your program files folder and find the FME folder
2. Open this little program:

3. Click on "Create FME Reader Connection" and specify the datasource.
4. Click OK and copy the Connection Parameters string you'll recieve. consider this the recipe for the FME .NET connection you'll do in Dynamo.

5. Fire up Dynamo and specify a log file location and paste the string you copied and use either of the two nodes like this:

Brilliant! :)

Project Fractal: Brute Force Your Engineering Calculations

Project Fractal has been around for a while now, and I have wanted to test it for what it is worth.
However, the examples I have seen are mostly pointed towards form finding and the architecture side of things, except of course MT Hojgaards excellent example with a parking garage, here: https://www.youtube.com/watch?v=E-3ts053FV0
In focusing only on formfinding and its like I feel we miss out on a lot of great potential uses for this piece of technology.

What I've been thinking of is how we could make a cross border link between the old way of doing things and the new technology that are evolving so rapidly. I want to bring one of those ideas to the table in hope that it can spur others into doing things like it and create more examples that are really useful. We may even help Autodesk in marketing this product, who knows..

Anyways, At our office we have a lot of "old" excel-sheets for doing calculations of random stuff. Yeah, I know.. It's not BIM-ish, but it's the real world. But what if we could take the intrinsic logic of and intellectual capital invested in those Excel sheets and transfer it into some of the newer tools for parametric and generative design and thereby add value to the already invested time in developing these, really quite advanced, Excel-sheets. And one of the case studies was an Excel-sheet for calculating minimum reinforcement anchoring length. Not entirely sure if that is the correct english term, but I think you catch my drift. The only problem for using this in Fractal was that you can't use scripts that open files, so the downside was that I had to transfer the logic of the standards into Dynamo Studio itself.

Now, once this was done I could upload the Script to Web and log in to fractal to run the script as many times as I wanted and then drag the handles in Fractal to see what kind of input parameters mattered the most for the anchoring length. A great way to apply a brute force way of thinking to existing formulas and standards! :)

In Dynamo Studio:

In Fractal:

(And for the really observant reader and avid Euocode user, you may notice I have taken some liberties when it comes to the actual calculations. As in many proof of concepts! ;) )
