CAD conversion for
America's legacy buildings.
We turn faded blueprints, scanned paper, raster images, PDF sets, and hand sketches into accurate, standards-compliant CAD drawings. 5,500+ projects since 1997. Every inquiry reaches the Director — not a call centre.

Send one drawing as it is — paper scan, raster file or PDF. We'll tell you the right route and return a free CAD sample within 48 hours.
Send a drawingEvery drawing passes a 3-step QA process.
Documented, repeatable, human-led. The step most competitors skip is why clients send us their legacy buildings again and again.
- 01
Scan Inspection
A second set of eyes reviews every source drawing before conversion begins. Marginal or illegible data is tagged and surfaced to the client, never silently guessed.
- 02
Overlay Comparison
Converted CAD is overlaid on the scan and checked object-by-object. Each element is toggled on and off; verified items are tagged so nothing is missed or double-checked.
- 03
CAD Corrections
Tagged items are corrected by an experienced CAD technician — layer, line type, text, or redraft. Errors affecting multiple sheets propagate across the set.
Five industries. One thing in common — legacy drawings that need to catch up.
What we had. What we did.
Real sheets from past projects: the scan we received beside the CAD we delivered. Client names withheld under NDA.
Exterior elevations, 1938 building
Four exterior elevations of a 1938 building, redrafted from a scanned legacy sheet into a clean, layered CAD drawing.
See the comparisonFirst-floor architectural plan
A dense first-floor plan — structural grid, walls, doors and room tags — redrafted from a scan onto separate layers.

Equipment room plans and sections with ductwork and piping, redrafted from a scanned mechanical sheet.
