# Kerfwise

> Design cabinets and furniture, get cut lists, optimised sheet layouts, costs and drawings. Kerfwise is a free cabinet and furniture CAD that runs in your browser. Build kitchens, wardrobes, bookshelves, desks, tables and beds from parametric cabinets with real joinery — including diagonal, L-shaped and angled corner cabinets — then get a grouped cut list with edge banding, guillotine or CNC sheet layouts (shaped parts too) with yield, offcuts and a lower bound, CNC G-code with drilling, a hardware list, a full cost estimate and dimensioned production drawings. Projects stay on your device; the same engine is available as API and MCP tools.

Kerfwise (Cabinet & furniture CAD) is a premium app of usefulweb.app (https://usefulweb.app/): a full program that runs in the browser. Its engine is deterministic and the same functions are exposed as tools, so an agent can compute exactly what the app shows.

## Limits
- Shaped cabinets cover the common corner types (diagonal, L-shaped, angled end, quarter round); free-form curved fronts and bent doors are not modelled, and quarter-round shelves are open (no curved doors).
- Nesting is heuristic: a layout is proven optimal only when it reaches the lower bound (gap 0); shaped parts are nested by their bounding box plus the notches inside it, not by true free-form polygon interlocking.
- CNC output is 2.5D for a 3-axis router: face drilling and profiles only. Edge holes (dowels in panel edges, cam bolts) and angled pocket holes are listed but need a horizontal drill or a jig; pockets, grooves and engraving are not milled. Always simulate the program before running it.
- Hardware positions follow common European (System 32, Blum-style) defaults; check your exact hinges and slides.
- The 3D view needs WebGL; edges are bevelled, not truly rounded, and textures are procedural (no photo materials).
- Phones get a simplified, mostly read-only layout; editing is best on a tablet or desktop.
