Curved openings and bridges

The arch generator creates the upper curve for gateways, windows, bridges, and roof ribs.

Build tips

  • Adjust height separately from width to choose a shallow or tall curve.
  • Thick mode works well for stone gates and bridge supports.
  • Mirror the preview left-to-right to keep both sides aligned.
