CSV export included.\n\nMethodology:\n- Every cabinet is generated with the Kerfwise cabinet engine (see kerfwise-cabinet-builder for the joinery rules); identical cut pieces (same material, size, grain and banding) are grouped into one row with all their labels.\n- Edge banding metres = sum of banded finished edge lengths × (1 + banding waste %, default 10 %), rounded up to 0.1 m.\n- Sheets: parts of each sheet material are nested with the kerfwise-sheet-nesting optimiser (kerf, trim margins, grain locked for grained materials); solid stock and worktops use first-fit-decreasing 1D optimisation.\n- Cost = materials (full sheets or used area × (1 + waste %)) + banding + hardware + labour (cut minutes per part, banding minutes per metre, drilling minutes per hole, assembly minutes per cabinet) + worktop cut-outs, then markup and tax.\n\nPrices are editable defaults, not quotes. Labour times are rough workshop averages — adjust them to your shop.
