Stucco & Moulding Generator – Altbau Cornices, Panel Frames, Arch Surrounds & Ceiling Rosettes (Geometry Nodes)
See README.md. Short: add any mesh object (it is ignored), add the Geometry Nodes modifier, pick Tidebone Stucco & Moulding, choose Element and Profile, set Width (and Height / Rise) and Profile Size, then add an Ornament row, Mitre Left / Right, Corner Blocks or a Keystone. The mouldings stand out of the wall plane towards −Y (same convention as Altbau Facade).
