The `free2ki` [FreeCAD](https://github.com/FreeCAD/FreeCAD) workbench enables you to apply materials to 3D models in FreeCAD, as well as to easily export them to VRML (.wrl/.wrz) files with correctly applied rotation and scaling for use in KiCad as well as Blender.

I created it as I wanted a fast to use, simple and less buggy/bloated alternative to the [kicadStepUp](https://github.com/easyw/kicadStepUpMod) workbench that just works and better integrates into my KiCad to Blender workflow ([pcb2blender](https://github.com/30350n/pcb2blender)).

## Usage

1. Switch to the Free2Ki Workbench.
2. Select the models or parts of models you want to apply a material too.
3. Use the `Set Materials` tool, to setup the materials you want (this tool can be used
   multiple times to setup multiple materials, on a single object)
4. Export the selected objects (or the whole file if nothing is selected) via the `Export`
   tool. This will create a `<project_name>.wrz` file, in the same directory your FreeCAD
   project file is in.
5. (optional) Install the [pcb2blender](https://github.com/30350n/pcb2blender)
   Blender addon and import your model via<br>
   `File -> Import -> X3D/VRML (.x3d/.wrl) (for pcb3d)`.<br>

### Materials

Missing anything from the selection of available materials?

Feel free to create an issue on the [mat4cad](https://github.com/30350n/mat4cad) repository, explaining what materials you'd like to see (possibly also how they'd look like in Blender) and I might add them in the next update!

## Installation

- (not available yet) via the builtin addon manager
  `Tools -> Addon manager -> Workbenches -> free2ki`

- (manual) Download the `free2ki_<version>.zip` from the
  [latest release](https://github.com/30350n/free2ki/releases/latest)
  and unpack its contents into your
  [FreeCAD Mod folder](https://wiki.freecadweb.org/Installing_more_workbenches#Installing_for_a_single_user).

## Other Projects

- All the 3D models of the [protorack-kicad](https://github.com/30350n/protorack-kicad) KiCad library, which contains all the custom symbols and footprints I use for eurorack module development, have been created using this workbench.

- The [pcb2blender](https://github.com/30350n/pcb2blender) workflow makes use of the [mat4cad](https://github.com/30350n/mat4cad) materials that this workbench lets you apply to your models. These materials will be recognized by Blender, and depending on the material type, different procedural textures/features will be used in Blender, making your models look more realistic.

## Credits

- The name of this project is inspired by the awesome [svg2shenzhen](https://github.com/badgeek/svg2shenzhen) Inkscape extension by [badgeek](https://github.com/badgeek).
