Ionadol Aura puts the five classical orders — Tuscan, Doric, Ionic, Corinthian, and Composite — into your hands wherever you stand. Point your camera at a real column, set the module from a single lower-shaft diameter measurement, and watch canonical proportions from Vignola and Palladio materialize as draggable hairlines over the stone itself.
The Canon Overlay is the heart of the app. Lay the member-height ladder, the entasis curve, the Ionic volute spiral, flute divisions, and intercolumniation span directly onto your photograph. Seat each line against the real stone until it fits, and the app returns a signed divergence in parts for every architectural member — shaft, capital, architrave, frieze, cornice. A two-axis bar chart makes the deviation visible at a glance, and a rendered canon plate can be exported straight to your photo library.
The Folio holds thirty-four reference plates arranged on five shelves: the five orders with full member ladders and Vignolan figures, six ornament types, six building stones, eight field instruments, and nine moulding profiles computed geometrically from their arc constructions. Each plate carries set-out rules, common faults, and on-site inspection tips drawn from the classical treatise tradition. The Profiles Bench lets you load up to three moulding sections side by side and lay any one directly over a survey photograph for immediate comparison against the stone.
Ionadol Aura is for architects, architectural historians, heritage surveyors, and students of the classical tradition who want a rigorous, fully offline field companion — not a style browser, but a precision bench for reading the built fabric against the canon.
