Draw, then save it or send it straight to Generate. Boolean ops (∪ − ∩) land in a later pass.

For staircase greenhouses: pick a stepped edge, then group sections into blocks.

Uses the drawn shape (or working polygon) as the boundary. Include/exclude masks come next.

Hexagonal grid — 6 equilateral triads per hexagon, grouped into horizontal bands (the row-equivalent unit: each shape is “… · Band N”), clipped to the boundary (edge units are partial). Uses the drawn shape or working polygon.

Cut the working polygon along a line, leaving a gap the width of the blade. Each piece becomes its own saved shape and the working outline clears. To slice one saved shape repeatedly, hit slice on its row.

Straight: click points on the map, Backspace removes the last one, double-click to finish the cut. Freehand: drag across the polygon. The pale band shows the blade at its true width.

The knife stays out for the next cut — press Esc (or double-click without drawing a path) to put it away.
