The windkit git repository can be found [here](https://git.erni-kollektiv.org/erni/windkit).
The FreeCAD model can be found in the `Cad` folder, the STEP file in the Export folder. If you are looking for the STEP file only, see [here](https://git.erni-kollektiv.org/erni/windkit/-/blob/master/Export/MainAssemblyWindkitRev1_201123.step).

We also provide 2D DXF files for all components that need to be laser cutted from aluminium, steel and wood multiplex. Those DXF files can be found at `Export/LaserCutterFiles`.
## Software Requirements
To use the CAD model as a reference during assembly, we recommend FreeCAD or CAD Assistant (with the STEP file). [CAD Assistant](https://www.opencascade.com/products/cad-assistant/) is a freeware CAD viewer for various formats and is multi-platform.
If you want to contribute to this project, test or modify the CAD model, we recommend the following FreeCAD version and workbenches. [FreeCAD (Link branch by realthunder)](https://github.com/realthunder/FreeCAD/releases/)
For the assembly process we've used the Assembly3 workbench. The workbench is bundled in the fork mentioned above, no additional installation is required. Additionally we use [Fasteners WB](https://github.com/shaise/FreeCAD_FastenersWB/releases/tag/last) for fastener groups, this workbench can be installed separately via the Addon Manager in Freecad. To get to know Assembly3, have a look at the [Assembly3 section of the FreeCAD Wiki](https://wiki.freecadweb.org/Assembly3_Workbench) and [realthunder's old FreeCAD Fork Wiki](https://github.com/realthunder/FreeCAD_assembly3/wiki). .

To inspect the DXF files we recommend QCAD. [QCAD](https://www.qcad.org) is a 2D CAD modeller.
## Structure of the CAD model
The CAD is organised into sub-assemblies and stored in their respective folders. The sub-assemblies are shown in the image below.

Each assembly folder contains:
* `Components.NAMEOFTHESUBASSEMBLY.FCStd` file containing all the parts of the sub-assembly
