## Overview

AutoCAD Redraw Skills provides two user-facing reconstruction workflows: evidence-backed rebuilding from an existing DWG, and image/PDF-derived CAD creation. The image workflow covers raster preflight, evidence-aware specifications, drawing, output inspection, preview rendering, and visual comparison; the DWG workflow fingerprints a source, prepares a custom prompt, and rebuilds and validates a drawing. The README documents these stages; sampled scripts show individual tool behavior, but do not establish that the scripts call one another, so workflow links cite the README.
