From parameters to a finished cut list.

Carcassist is a free planner for cabinets and furniture carcasses that runs entirely in your browser. Configure one or more carcasses through parameters, combine them into a run, see everything instantly in 3D and generate every document for cutting and the workshop.

Every part, exactly to size.

• Dimensions, panel thickness and material freely configurable — even per part.
• Construction: continuous sides or a continuous top/bottom.
• Joinery: dowels, Domino, Lamello, screws or groove — with drilling pattern.
• Corner joints: box joints or dovetails — through and half-blind, as real geometry in 3D and the drawing.
• Top as a full panel or as rails (flat or upright) for base cabinets.
• Back panel grooved (inset or slid in from below) or surface-mounted.
• Combine several carcasses into a run — with a continuous plinth and a single worktop across equal-height cabinets.

Open, doors or drawers — per compartment.

• Open, doors or drawers — different for each compartment.
• Overlay or inset doors, with hinge-cup boreholes.
• Drawers with individually defined heights, runner clearance and front material.
• Drawer bottom in the groove (all-round or slid in from the back) or underset.

Split the carcass, place the hole rows.

• Split center wall (vertical) or divider shelf (horizontal) → two independently configurable compartments.
• Adjustable shelves with shelf-support boreholes.
• LR32 / System-32 hole rows for the sides.

• Parts list with dimensions, grain direction and edges.
• Cut list / saw plan with offcut optimization and cutting sequence — plus an interactive cut preview that walks through every saw cut step by step.
• Material & cost list, hardware & machining list.
• Scaled technical drawings incl. dimensioning of holes and grooves.
• Plinth and worktop per carcass.
• DXF export per part (outline, holes and grooves on their own layers) for CNC/CAM.
• 3D model as STEP: true parametric solids (not a mesh) with grooves, holes and joints cut in — each part a named body, grouped by cabinet, ready to open in FreeCAD or Fusion.
• Export as CSV; save and load projects as JSON.
• Automatic in-browser saving; share projects by link.
• Reusable material library across projects.
• Multilingual (German/English), light and dark theme.
