Arch Construction

Arch Construction is a design tool for planning and inspecting masonry arches. Start with the arch dimensions, choose the type of arch, set the number of stones, and adjust the design until it looks buildable. The app focuses on the key design choices, while the underlying geometry is handled automatically. With Arch Construction you can: • Design arches from a given span and height • Explore one-centred, three-centred, and flat arches • Adjust stone count, coursing, joint thickness, and related geometry • Inspect the arch with clear voussoir layouts • Edit individual voussoirs when needed • Use different end kinds for coursed stones • Export drawings to SVG and DXF Arch Construction is built for builders, architects, students, designers, and anyone with an interest in the geometry of traditional masonry arches. All features are included in the app purchase. No in-app purchases. No subscriptions. Works offline. Whether you are studying arch geometry or preparing a layout for a real project, Arch Construction gives you a clear workspace for understanding, refining, and exporting masonry arch designs.
