Drop a plan image on the canvas, or import one. It sits faintly under your tracing as a guide and is never included in exports.

Diagram mode

Invert (void as solid)

Figure-ground paints built mass solid black. Nolli renders the mass as poché hatch. Invert swaps figure & ground.

Edit

Export

Exports the clean diagram only — built mass on ground, without the reference image. Rectangles & polygons stay true vector in the SVG.
