Window Design Software
Mobile-first window design software for fabricators, architects, and fitters. Draw any window configuration with millimetric accuracy — no CAD training required.
Professional Window Design on a Phone
Purpose-built for fenestration work — faster than AutoCAD, more accurate than pen & paper.
Multi-Panel Configurations
Design single, double, triple, and four-panel windows. Add transoms, mullions, fanlights, and sidelights with drag-and-drop controls that produce dimensionally accurate drawings.
Opening Types Library
Casement, tilt-turn, sash, top-hung, side-hung, French, pivot, fixed, and tilt-only — all built in. Each opening applies the correct hardware, seals, and airflow logic automatically.
Real-Time Dimensions
Every line of your drawing carries a live dimension. Change frame width and glass sizes, mullion positions, and hardware offsets update in real time — no manual recalculation.
Export to Production
Export cut lists, glass schedules, and technical drawings as PDF or CSV. Feed straight into your saw list, glass supplier order, and production floor with zero re-entry.
