Five Architectural Modules Built for Commercial Accuracy

Deterministic geometry calculations combined with multimodal vision prevent costly bidding mistakes.

Automatic Title Block Scale Detection & Verification

Never suffer a 10× scale error. The engine parses architectural title blocks (`1/4" = 1'-0"`, `1:50`, `1:100`), validates dimension witness lines against known grid spans, and enforces manual confirmation if scale ambiguity is detected.
