The Catalogue

Every product is a generator: parameters in, parts out. Adding one to a design gives you its own parameter form, and its geometry is rebuilt from those parameters every time they change.

ProductidWhat it is
Project Boxproject_boxGlued finger-jointed box with a captured bottom
Pinned Project Boxpinned_boxThe same box, knock-down: hooked tenons drawn tight by flat pins
Produce Boxproduce_boxThe glued box with every face turned into a honeycomb grille — a ventilated crate
CabinetcabinetA single column of openings — drawer, door, open bay or display — in a finger-jointed carcass with a captured back
DrawerdrawerA lean finger-jointed box sized to a cabinet opening
DividerdividerEgg-crate grid of half-lapped boards, sized to a box's interior
TraytrayA floor with border walls and per-bay half-lap dividers
Skadis Panelskadis_panelPegboard panel cut to the IKEA Skadis hole pattern
PlateplateA bare rectangular blank for engraving — nameplate, award, label
MarkermarkerAn engrave-only branding tile: artwork plus a line of text, nothing cut

The id is what appears in a saved .tenon file and in the HTTP API. The title is what the app shows.

Sizes are external

Where a product takes L, W and H, those are outside dimensions. The interior is whatever is left after the walls, and the app reports it back to you — a box with 310 mm outside length in 9 mm ply has a 292 mm interior, and the readouts say so rather than making you work it out.

This is the right way round for the usual question, which is "will it fit on that shelf", not "how thick are its walls".

Parameters are validated

A product refuses parameters it cannot build — a box too short for its own handle, a lidded box too thin for the lid notch. The message says which dimension is fighting which, and what to change. That is a contract failure, not a bug: it is the product telling you the object cannot exist in that material.

Adding products

Products are discovered from the engine, not hard-coded into the UI. A new product appears in the picker with its own form the moment the engine offers it — no UI change, and no update to this guide's mechanics.
