Draw polylines and polygons with real-time rounded corners in QGIS.
About
This QGIS plugin enables you to digitize polylines and polygons with live fillet (rounded corner) previews. It automatically detects the active layer type (line or polygon) and adapts its behavior accordingly. Adjust the fillet radius interactively using keyboard shortcuts while drawing—ideal for sketching roads, pipelines, boundaries, or any feature requiring smooth transitions. Unlike traditional workflows that apply fillets *after* geometry creation, this tool integrates rounding directly into the digitizing process—mimicking how designers naturally sketch on reference maps.
