Courselines (with coursing cutting) Voussoir joints Stepped beds (bonded extrados) Intrados division points

Model type: Traditional. Joints are perpendicular to the intrados (Claveau-module division) and cut at their governing courseline, bonding the voussoirs into the ashlar bed. Jack lintels use the rule-of-one-and-a-half focus.
