One source of truth

The same dimensions drive 3D, drawings, materials and calculations.

Estimates are clearly separated from sources, geometry and physical tests.

Plans are intended for real builds, not just attractive renders.

From model to workshop

There are no separate marketing and technical dimensions. The same canonical model drives the view, cut list, calculations and build guide.

Parametric 3D, roof-off/exploded views and SVG technical drawings from the same dimensions.

12 mm, 9 mm and XPS parts are compiled and packed into planning stock with margins and kerf.

Framing lengths, service roof, hinges, latches and a provisional fastening schedule.

Quantities come from the compiler while the user enters real local prices and currency.

Build steps with locally saved progress, focus mode and print/PDF output.

The PWA cache keeps previously visited models available when workshop connectivity is unreliable.

Reference set
