Is it possible to automate the creation of complex PCB contours using Python in KiCad?
Yes, automating the creation of complex PCB contours is possible using Python in KiCad. The script provided illustrates how to add curved lines to create a custom-shaped PCB:

```python
import pcbnew
from pcbnew import wxPoint, wxPointMM

def add_line_arc(start, center, angle=90, layer=pcbnew.Edge_Cuts):
    board = pcbnew.GetBoard()
    arc = pcbnew.PCB_SHAPE(board)
    arc.SetShape(pcbnew.SHAPE_T_ARC)
    arc.SetStart(start)
    arc.SetCenter(center)
    arc.SetArcAngleAndEnd(angle * 10, False)
    arc.SetLayer(layer)
    arc.SetWidth(int(0.1 * pcbnew.IU_PER_MM))
    board.Add(arc)

# Define positions and create complex contours
# ... (rest of the script)
add_line_arc(start, center)

pcbnew.Refresh()
```

This approach is ideal for PCBs requiring non-standard shapes or for fitting into specific mechanical spaces, where curved contours are necessary.
