Description
Turning a skewed photo of a part, a scanned old drawing or a hand sketch of a floor plan into an editable CAD file usually means tracing it line by line. AutoCAD Redraw Skills hands that job to Codex: drop in the image and ask, and it checks image quality and dimension evidence, writes a redraw spec, drives AutoCAD to draw an editable DWG, then overlays the result on the original to measure the error.
It does not fake precision: every dimension is labelled as read from the drawing, scaled, inferred or unreadable, and a drawing without units is never silently assumed to be in millimetres. A second skill covers the case where a DWG or PDF exists and rebuilds it entity by entity with matching layers, blocks and dimensions. Requires Windows, an installed AutoCAD and Python.
Image to DWG: photos, scans, screenshots and hand sketches become an editable DWG plus a DXF for inspection.
Five redraw modes: strict dimensioned, general, hybrid, visual trace and geometry only, chosen by drawing quality and purpose.
Evidence levels: each dimension is marked known, scaled, inferred or unreadable, keeping visual similarity separate from real accuracy.
Input preflight: checks sharpness, skew and calibration anchors up front and says so when an image is too poor.
Result comparison: renders a CAD preview and produces side-by-side, overlay and difference images with edge-distance metrics.
Exact DWG rebuild: with a source DWG or PDF, extracts entities, layers, blocks and dimensions into a custom prompt, redraws through AutoCAD COM and verifies entity counts and type distribution.
