Is it possible to automate the shaping of PCB edges based on component placement using Python in KiCad?
Yes, automating the shaping of PCB edges based on component placement is possible using Python in KiCad. The script provided automates this by adding custom-shaped lines to the Edge_Cuts layer around certain components:

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

def add_line(start, end, layer=pcbnew.Edge_Cuts):
    board = pcbnew.GetBoard()
    segment = pcbnew.PCB_SHAPE(board)
    segment.SetShape(pcbnew.SHAPE_T_SEGMENT)
    segment.SetStart(start)
    segment.SetEnd(end)
    segment.SetLayer(layer)
    segment.SetWidth(int(0.1 * pcbnew.IU_PER_MM))
    board.Add(segment)

# Script for custom edge shaping
# ... (rest of the script)
add_line(start, end)

pcbnew.Refresh()
```

This method is useful for creating custom PCB shapes, particularly when the board needs to fit specific mechanical constraints or design aesthetics.
