FreeCAD Model of a Mini Wind Tunnel
I want to share this small project where just recently I used FreeCAD and its Arch Panel Tools to complete an open source documentation. The original design was made two years ago with Rhino 3D, but I always wanted to include a full 3D model in FreeCAD to have a full open source project. When the Arch Panel Tools were incorporated into FreCAD (thanks, Yorik) it was the right moment to built the 3D model, because this design is inspired by the WikiHouse Project: all its parts are MDF panels (3-6mm) cut in a laser cutter machine. So the Arch Panel Tools is the ideal for this task.
The project website is here: https://miniwindtunnel.wordpress.com/
The mini airflow tunnel project is an easy to use and low-cost tool for wind analysis with an empirical approach on physical wind simulation. This tool is a mini airflow tunnel that can provide graphical representations of airflow data for a quick feedback, visualisation and analysis, for architects and designers in the early design stage.
The mini airflow tunnel project is an association of analogue and digital technology: it uses electronic components for arduino technology, Rhino 3D software with Grasshopper3D and Firefly plugins for graphical visualisation of airflow data in real time.
The web includes all the documentation and tutorial to build and operate this mini wind tunnel. But it did not have a 3D model of the MDF parts to work as a template for fabrication. Only DXF files. Now I created a FreeCAD file with all the MDF parts of this project as Arch panels. As I mentioned before, the design of this mini wind tunnel is based on the wikiHouse concept. All parts can be cut with a laser cutter machine and assembled without tools or screws. In a second post I'll share the FreeCAD files.

Re: FreeCAD Model of a Mini Wind Tunnel
Here the FreeCAD files and more images of the template extracted from the panels of the 3D model.
With FreeCAD I could fix some errors from the old DXF templates. To import these DXF files to FreeCAD and using them for Arch panels was easy. But I had problems with the curves lines from DFX to create wires.

Re: FreeCAD Model of a Mini Wind Tunnel
This is one of several user showcases recently, where I think FreeCAD is lifted to a higher level. No one can be in doubt of FreeCAD's capabilities, when they see these pictures. Congratulation with the result. After all the hard work, now you have a serious tool. I wish you a lot of time playing with you new ”toy”.

Re: FreeCAD Model of a Mini Wind Tunnel
Amazing work @bitacovir!!! I'm really happy you "jumped" into FreeCAD
This whole Path/Wikihouse/Arch panel tool is really a turning point I think... There is really something new happening there.
Your "cross" clip system is really interesting. Did you invent it?

Yorik. This project was developed in the SIAL (Spatial Information Architecture Laboratory) in RMIT University. Other people help me to develop it. The constructive system of clips for the module's parts was created by Daniel Prohasky. https://miniwindtunnel.wordpress.com/about/
Currently, to operate the mini wind tunnel you need Arduino+Rhino 3D+Grasshopper3D+Firefly. Maybe in the future, FreeCAD could be used instead Rhino+Grassopper to work with Arduino for graphical visualisation of data.

viva la revolutione en open source, amazing stuff
Re: FreeCAD Model of a Mini Wind Tunnel
Looking good!
Re: FreeCAD Model of a Mini Wind Tunnel
Looks good. I'm wondering how do you get the flat patterns from the 3D model? You used some custom scripts?
