Join me @ Forum Autodesk 2016 (Warsaw)

Just a quick update – I’ll be giving a presentation on Forum Autodesk 2016 in Warsaw. I’ll be sharing a stage with two colleagues and each of us will show a different approach to a different, real life coordination problem. My lecture is about everyday use of Dynamo in multidisciplinary projects – more specifically – framing coordination with structural team.

What I’m working on – Column arrangement coordination in Dynamo

…but let me start with explaining WHY I’m doing this. Imagine a high rise located somewhere in London, It will have 60-something floors, around 18000 beams, more than 2000 columns – and 2-5 people working on the structural model, just to make the tight deadlines possible. It would be hard to keep track. Now imagine a lot of design changes, structural supports moving left and right, columns disappearing and appearing again. And to top it all – very restrictive column schedule macro that doesn’t take “almost in line” as an answer. I need to be able to quickly see if all the columns are in line, are the column numbers assigned correctly and were there any last-minute design changes that I’m not aware of.

Now we get to the Dynamo part. This is what I have so far, and keep in mind this is just a very early version of this concept:


So what’s the deal here? First, we get all the columns from the model and choose the column “path” that we’re interested in (C12 here). Then it get’s trickier – as far as I know, Dynamo 1.1 (which I’ve used to write this) doesn’t have an easy way to get X,Y location of the center of the column (I know there’s a node for that in 1.2), so I’ve came up with following workaround: we get the coordinates value from Element.Solid – asking for maximum and minimum Y (thus getting the point in the middle), and we subtract this with value of the column below. If it’s zero – columns are in line. To make this work, columns should be sorted according to Z value, and to my suprise this wasn’t the default – somehow slopped columns mess up this order (that’s why the counter-intuitive sorting method)

As I said, this is still very early version, and here are my plans for further development:

  • Exporting to Excel
  • Export all the columns, not just one “line”
  • Checking X,Y values at the top and bottom, so that slopped columns won’t be seen as an “value other than zero”

Feel free to comment on this script – I’m still learning here!

First project in Revit

What’s better way to start of this journal than to write about my first BIM project! It all began almost three years ago, and my starting point was my master thesis, student exchange programme and learning about this crazy BIM-thing in Scandinavian countries (first software I’ve tried was Tekla). I’ve connected all the dots and thought to myself – “why not give myself a challange, and maybe learn something in the process?”

The idea of my master thesis was to recreate an existing housing project located in Warsaw using BIM software (in this case – Revit), provide an analitical model within the same file that could be exported to structural software (in this case – Robot Structural Analysis) and show that such an aproach could bring cost and time saving benefits.


For the modelling part I was using “paper” documentation, but because the building wasn’t very complex – it wasn’t a terrible downside. My modelling software of choice was Revit 2014, upgraded later to 2015. I’ve issued the final copy as native file (.rvt), but if I was to repeat that project, I’d definetly use .ifc standard (and I’d add another chapter to my thesis explaining why that’s the right approach to have).

I’ve tried to use the “purest” software I could – i.e I wanted to use default solutions to fully learn software capabilites. However, seeing all that Revit had to offer, for the purpose of creating shop rebar drawings I’ve used SOFiSTiK Reinforcement Detailing.


Having a working analitical model within a structural model wasn’t as simple as I thought it would be, so I’ve spent a lot of time moving columns & walls around (Robot doesn’t take misalignments very well), and If I were to do it again, I’d look for some smarter aproach (Dynamo?).


Not to make this post longer than in should, I’ll give some bullet points:

  • Structural and analitical information were matching – although I’m not sure if that could be achieved if the project would be more complex
  • Loadings and foundation were modelled in Revit – so that Robot would be used just for calculation
  • Loading combination were done in Revit, but I wouldn’t recommend such a solution
  • Rebar was modelled in Revit, wasn’t easy but It made schedulling faster than ever

Let’s hope for the best

…and I’m stuck already. I guess it’s hard to write when you’re still not sure about the outcome of this endeavour. Anyway, I’m starting a blog about my daily worklife, in a clumsy attempt to catch “on paper” anything that could be mildly interesting for someone besides me. Wish me luck!
