How to script arc-based PCB outlines around components in KiCad?
Scripting arc-based PCB outlines around components in KiCad can be achieved using Python. The script provided includes a method for creating a custom PCB outline with arcs that are positioned relative to the components:

```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)

# Script to create arc outlines around components
# ... (rest of the script)
add_line_arc(start, center)

pcbnew.Refresh()
```

This method is useful for PCBs that require tailored outlines to match specific design requirements, providing flexibility in the board's physical layout.
