Parametric wardrobe/cabinet automation for BricsCAD Mechanical — anyone interested?

We are building a central parametric CAD/CAM engine for wardrobes, walk-in closets and built-in furniture. Instead of drawing every wardrobe manually, the user changes parameters and the engine rebuilds the 3D model: cabinet body, shelves, drawers, hanging rods, filler panels, plinths and, later, automatic dimensions on layout sheets, plans and sections.

The project is developed in BricsCAD / AutoLISP. The current focus is correct geometry, construction rules, variants, safe rebuilds and a stable central engine. CNC, BOM and cutting lists are planned later.

What the system can control

The model supports wardrobes with or without an internal partition. It can work as an M1 / M2 layout with a P1 partition, or as a full wardrobe without a partition.

The system can change:

• width, height and depth,
• partition on / off,
• single or double shelves,
• automatic or manual shelf positions,
• automatic or manual drawer fronts,
• drawer box depth adjusted to cabinet depth and runners,
• hanging rods under a shelf or positioned manually,
• filler panels and plinths,
• thicknesses of sides, shelves, backs, fronts and other elements.

A key locked rule is:

SHELF_ABOVE_Z1 = highest drawer front Z2 + 30 mm

This rule works for both M1 and M2.

Current stable checkpoint

Current PASS file:

SZ01_MASTER_V2B34_V8_V12_MASTER_V26E_FIXB_REKA_AUTO_MIX_POLKA_ZAWSZE_30_PASS.dwg

This file has DBMOD = 0 and is the current rollback point.

Confirmed in this checkpoint:

• M1 shelf above drawers: highest drawer Z2 = 472, shelf Z1 = 502, gap = 30 mm,
• M2 shelf above drawers: highest drawer Z2 = 732, shelf Z1 = 762, gap = 30 mm,
• 6 drawer fronts,
• 12 drawer box sides,
• 6 drawer bottoms,
• 6 drawer backs,
• 2 shelves above drawers,
• 8 ordinary shelves,
• 2 hanging rods,
• 4 drawer-side filler panels,
• 4 support bases,
• 4 internal side panels,
• P1, BCT, SZ02 and SZ03 protected.

Project demonstration

The system can show three wardrobes standing next to each other in one built-in wall. After changing parameters, the same wall can rebuild with different widths, heights and internal layouts.

Example:

• before: height about 2300 mm, widths 1200 / 1000 / 800 mm,
• after: height about 2600 mm, widths 800 / 1200 / 1000 mm.

The transformation can change lower shelves into a hanging rod, replace single shelves with double shelves, change drawer quantity, use different drawer front heights, and add rods in different modes.

This is not manual redrawing. The goal is: change parameters, rebuild the model.

Single wardrobe parameter table

Planned global changes

Next plans

Next we will run operator-input tests: the LSP asks for values, the user enters real parameters, and the engine validates the result. This will test manual drawer heights, manual shelf positions, automatic shelves, rods, dimension changes and the locked 30 mm shelf-above-drawers rule.

After M1/M2 tests, we plan to transfer the same logic to a fresh FULL wardrobe without a partition. Later we want global changes for the whole project and automatic dimensions in layouts, plans and sections.

Future expansion

The engine may later support:

• kitchen furniture,
• internal doors,
• decorative wall panels,
• wall panels with mirrors,
• wardrobe fronts with aluminium frame + glass,
• wardrobe fronts with aluminium frame + mirror,
• routed fronts and other front systems.

The goal is one central parametric engine, not separate scripts for every product type.

Final direction

We are building a V8–V12 central engine for parametric wardrobes and furniture built-ins. A parameter change should rebuild the model, not require manual drawing repair. This is the foundation for wardrobes, walk-in closets, full wardrobes, partitioned wardrobes, corner wardrobes, kitchens, doors, wall panels and front systems.
