Detect the likely sheet scale
AI reads the scale off the sheet, or calibrate a custom scale yourself by drawing a known dimension.
Use case
AI scale detection for construction PDFs.
Set scale faster, reduce measurement mistakes, and keep every takeoff traceable to the construction drawing that produced it.
Why teams use it
Organized around the sheet set.
Straighten the scan first
Deskew and perspective correction clean up scanned or photographed plans so the geometry measures true before scale is applied.
Carry scale into takeoff
Once calibrated, every takeoff tool — area, linear, count, wall, plane, perimeter — measures against it, and quantities post to priced categories.
FAQ
Questions this page should answer.
What is AI scale detection?
AI scale detection helps identify or suggest the correct measurement scale for a construction drawing or PDF.
Can AI scale detection be wrong?
Yes. Users should review scale suggestions before relying on measurements or takeoff quantities.
Does Redliner support manual calibration?
Yes. Redliner supports scale workflows where a user can verify or set a known dimension.
