This is the source-of-truth sheet for default cabinet construction rules. The point is to keep all recurring assumptions in one place so cabinet family sheets pull from here instead of repeating logic everywhere.
Think of this as one long standards table grouped by section. You can later reference these values from the cabinet family sheets.
| Category | Setting | Value | Unit | Notes |
|---|---|---|---|---|
| Construction | ||||
| Construction | Standard board thickness | 16 | mm | Main carcass board thickness |
| Construction | Standard back thickness | 6 | mm | If using full board back instead of hardboard |
| Construction | Standard hardboard thickness | 3 | mm | For standard back board |
| Construction | Standard divider thickness | 16 | mm | Usually same as board thickness |
| Gaps | ||||
| Gaps | Door side gap overlay | 2 | mm | Each outer side |
| Gaps | Door side gap inset | 1 | mm | Each outer side for inset fronts |
| Gaps | Gap between double doors | 2 | mm | Between adjacent doors |
| Gaps | Gap between drawers | 3 | mm | Between stacked fronts |
| Gaps | Gap between door and décor rail | 3 | mm | Top front clearance |
| Floor-standing | ||||
| Floor-standing | Standard feet height | 100 | mm | If using adjustable feet |
| Floor-standing | Standard toe-kick/base height | 100 | mm | Use if cabinet is on fixed base instead of feet |
| Rails | ||||
| Rails | Standard back rail height | 100 | mm | Top back rail |
| Rails | Standard front rail height | 100 | mm | Adjust if design family differs |
| Rails | Standard 50 rail height | 50 | mm | Secondary support rail |
| Rails | Standard décor rail minimum height | 50 | mm | Can be larger when specified |
| Shelves | ||||
| Shelves | Standard shelf deduction | 20 | mm | Typical depth reduction from bottom panel |
| Shelves | Shelf clearance gap | 3 | mm | Total fit clearance or per side — define clearly |
| Drawers | ||||
| Drawers | Standard runner type | Soft-close | text | Default runner family |
| Drawers | Standard runner deduction | See runner spec | text | Keep exact number once standardized |
| Drawers | Drawer bottom deduction | 78 | mm | Example from prior logic sheet — verify |
| Drawers | Drawer back height rule | 148 / 86 | mm | Depends on drawer front height |
| Doors | ||||
| Doors | Overlay rule | Side depth = D - 16 | formula | Door overlays front face |
| Doors | Inset rule | Side depth = D | formula | Inset front sits inside opening |
| Mounting | ||||
| Mounting | Wall-hung bracket assumption | 2 brackets | qty | Default wall-hung fixing assumption |
| Mounting | Feet quantity assumption | 4 feet | qty | Default floor-standing assumption |
