Use a second known dimension after calibration to catch scale or page-size problems early.
Know when to recalibrate
- 1
Check mixed-scale PDFs
Treat each page with a different printed scale as a separate calibration risk.
- 2
Watch scanned drawings
Scanned sheets may not match the printed title block scale exactly.
- 3
Recheck after replacement
If a drawing file is replaced or rotated, confirm measurements still match known dimensions.
Recalibrate safely
- 1
Pick a clear dimension
Use the longest reliable printed dimension available.
- 2
Set scale again
Run Set Scale and enter the real length and unit.
- 3
Review existing quantities
Check existing measurements after scale changes before relying on totals.
