TWArch Master is an innovative next-generation AI agent that converts hand-drawn historical architectural drawings into construction-ready parametric 3D models — purpose-built for architectural heritage restoration. Conventionally, restoration process demanded months of fragmented specialist work across historians, structural engineers, and CAD drafters, with no integrated tool connecting historical records to buildable output. TWArch Master closes this gap. Based on trained AI object recognition model, it automatically detects and classifies structural components from scanned drawings, converts them into editable 2D and/or 3D CAD objects, and enables real-time design modification via natural language — accelerating restoration workflows by up to 60x and eliminating up to 90% of material waste through digital pre-simulation. Validated through a registered patent and 3 acknowledged research papers, succeeded in virtual restoration of a lost heritage from historical drawings and ruins — TWArch Master delivers professional-grade heritage restoration to any team, regardless of budget, region, or technical depth.
