How to script the creation of custom vias for advanced PCB design in KiCad?
Scripting the creation of custom vias for advanced PCB design in KiCad can be achieved using Python. The script snippet provided allows for the creation of a via with specified position, diameter, and drill size, enabling custom via layouts:

```python
import pcbnew

# Script for custom via creation
board = pcbnew.GetBoard()
pcb_via = pcbnew.PCB_VIA(board)
pcb_via.SetPosition(pcbnew.wxPointMM(x, y))
pcb_via.SetWidth(int(via_diameter * pcbnew.IU_PER_MM))
pcb_via.SetDrill(int(via_drill_diameter * pcbnew.IU_PER_MM))
pcb_via.SetNetCode(net.GetNetCode())
board.Add(pcb_via)
```

This script is effective for tailored via routing in PCB designs, where specific placement and size are crucial for the board's electrical performance and reliability.
