Pattern and purchase layers
Measured rectangles and L-shapes now support grid, running-bond, and compatible basket-weave field sketches. The drawing marks the starting corner, horizontal baseline offset, rows, and edge cuts; the established quantity engine still estimates the selected pavers, border units, base, bedding, and other entered products.
Before selecting manufactured edge restraint, mark each purchased boundary on the paver field sketch; then compare the result's edge schedule with that sketch.
Adjustments remain separate
Geometric cut excess, broken-unit reserve, layer order factor, package surplus, and pallet surplus are presented as different quantities rather than one ambiguous waste number.
Important limits
Complex borders use an explicitly additive measured purchase count; their installed footprint is not inferred. Fabric lanes require one simple rectangle. Permeable pavers are materials only; reservoir, underdrain, infiltration, storage, and overflow design are outside this calculator.
