This is a quick video showing a tool I created using Rhino to calculate simple fixed axle swept path analysis on site plans for work.
This was quite a complicated program to create, but is able to be reused on multiple sites, for multiple vehicles. Based on the Ackermann steering and parametrised geometric principles.
It works really well in my workflow in architecture, as I can export siteplans as DWGs, import them into Rhino, perform the swept path analysis and bake them back into a DWG to be reimported into the BIM model.
If there’s any interest in it, I may upload a .GH file of the script for others to try out.
One of my latest obsessions has been tinkering with Rhinoceros and Grasshopper – whilst I still have my 90 day trial of the software, i’ve been trying to teach myself as much as possible about the benefits of coding in design/architecture. The blog ‘I Eat Bugs For Breakfast‘ by David Rutten has been invaluable in explaining many of the subtleties of the software.
I had originally heard about Grasshopper and parametric design in an interview with Bjarke Ingels of BIG architects (BIG.dk) where they stated that the connection with coded elements was crucial to their design strategies, allowing them to quickly iterate through options and form amazing computer generated landscapes.
The software also happens to work really well with ARCHICAD – the BIM software that the practice I work at has invested in, so it seems like a good match.
I created a little video that walks through one use-case I’ve found for the software, in helping to advise/evolve a solution to calculating efficient timber spans for floors (not very exotic, I know – but handy nonetheless), for giving a good estimate on structural depths whilst minimising the amount of timber required for the build.
Disclaimer: as architects we never advise on actual structural elements, and cannot guarantee any safety – that’s what structural engineers are brought on board for – but in any case, it’s always nice to get an idea of the structural zone the building will require…

So all in all, a very fun and interesting project, definitely with some scope for development as well as fine tuning — I’m also quite sure that there has to be an easier way of performing a few of the procedures, but for the time being I am really enjoying the process! If you’ve got any questions or comments on the script, let me know in the comments.
My previous Grasshopper script was a push-pull brick facade generator (very pretty), which I hope to also do a video about as well, so stay tuned for that!
