Courselines (with coursing cutting) Voussoir joints Stepped beds (bonded extrados) Intrados division points Trimmed Claveaux Radial projections (dashed) Cascade cut to blocks below Springer stones (segmental & jack)

Model type: Traditional. Joints perpendicular to the intrados, cut at their courseline; vertical risers and beds bond each stone into the ashlar (tas-de-charge); the keystone rises one course when the plateau permits. Drag any window on the sheet — the voussoirs re-solve live.
