## What is Kindred Create?

Kindred Create is a fork of [FreeCAD](https://www.freecad.org) that adds integrated tooling for professional engineering workflows. It ships two custom workbenches and a purpose-built dark theme on top of FreeCAD's parametric modeling core.

**ztools** -- A unified workbench that consolidates part design, assembly, and sketcher tools into a single interface. Adds custom datum creation (planes, axes, points with 16 creation modes), pattern tools for assemblies, an enhanced pocket with flip-side cutting, and spreadsheet formatting commands.

**Silo** -- A parts database system for managing CAD files, part numbers, revisions, and bills of materials across teams. Includes a Go REST API server backed by PostgreSQL and MinIO, with FreeCAD commands for opening, saving, and syncing files directly from the application. A dock panel provides in-viewport browsing and search.

**Catppuccin Mocha theme** -- A dark theme applied across the entire application, including the 3D viewport, sketch editor, spreadsheet view, and tree view. Uses spanning-line branch indicators instead of disclosure arrows.

Kindred Create is maintained by [Kindred Systems LLC](https://www.kindred-systems.com).

## Installing

### Prebuilt packages (Linux)

Download from the [releases page](https://git.kindred-systems.com/kindred/create/releases).

**Debian/Ubuntu:**

```bash
sudo apt install ./kindred-create_*.deb
```

**AppImage:**

```bash
chmod +x KindredCreate-*.AppImage
./KindredCreate-*.AppImage
```

### Building from source

Kindred Create uses [pixi](https://pixi.sh) for dependency management and CMake for building.

```bash
git clone --recursive ssh://git@git.kindred-systems.com:2222/kindred/create.git
cd create
pixi run configure
pixi run build
pixi run install
pixi run freecad
```

Debug and release variants are available (`pixi run build-debug`, `pixi run build-release`). See `CMakePresets.json` for platform-specific presets covering Linux, macOS, and Windows.

For general FreeCAD compilation guidance, see the FreeCAD wiki for [Linux](https://wiki.freecad.org/Compile_on_Linux), [Windows](https://wiki.freecad.org/Compile_on_Windows), or [macOS](https://wiki.freecad.org/Compile_on_MacOS).

## Usage

Kindred Create is compatible with standard FreeCAD workflows. The [FreeCAD wiki](https://wiki.freecad.org/Getting_started) covers general usage.

### ztools

Select the ztools workbench from the workbench selector. It presents consolidated toolbars from PartDesign, Sketcher, Assembly, and Spreadsheet in a single interface. ZTools commands are also injected into the PartDesign workbench menus and toolbars automatically.

See `mods/ztools/` for workbench-specific documentation.

### Silo

Silo requires a running server instance. See `mods/silo/README.md` for server deployment instructions.

The FreeCAD workbench reads configuration from:
- `SILO_API_URL` -- Server API endpoint (default: `http://localhost:8080/api`)
- `SILO_PROJECTS_DIR` -- Local projects directory (default: `~/projects`)

On first launch, Kindred Create prompts for Silo server configuration. Silo commands (Open, Save, Commit, Pull, Push, BOM) are available in the File menu across all workbenches.

The `mods/` workbenches are git submodules. If you cloned without `--recursive`, initialize them with:

```bash
git submodule update --init --recursive
```
