   Fill (tool)

Fill an enclosed area.

An area enclosed by two arcs and two crossing lines; a click badge inside marks where you click to fill it.

Menu: Combine > Fill | In depth: Regions & booleans

Click inside any area that is fully enclosed by other geometry and Locus fills it - even when the boundary is made of separate lines and arcs that merely cross, not a single drawn shape.

The fastest way to turn drawn lines into something solid. Click inside any space your geometry already encloses and Locus traces the surrounding curves and hands you a region.

The region stays tied to those curves. Move any of them and the fill re-solves to match, and deleting the boundary deletes the fill with it.
