Is it possible to script complex PCB track geometries, like arcs and curves, in KiCad using Python?
Yes, scripting complex PCB track geometries, including arcs and curves, is possible in KiCad using Python. The given script shows how to create a 90-degree arc track between two pads:

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

def add_track_arc(start, mid, end, layer=pcbnew.F_Cu):
    board = pcbnew.GetBoard()
    track = pcbnew.PCB_ARC(board)
    track.SetStart(start)
    track.SetMid(mid)
    track.SetEnd(end)
    track.SetWidth(int(0.25 * 1e6))
    track.SetLayer(layer)
    board.Add(track)

# Script to define start, end, and mid points for the arc
# ... (rest of the script)
add_track_arc(start1, mid, end1)

pcbnew.Refresh()
```

This approach allows for the creation of tracks with specific geometrical shapes, useful for advanced PCB design and layout optimization.
