Scale Calibration
Set a printed imperial scale or 1:N ratio from the scale readout, or press K and draw a known distance; linear and area quantities then recompute.

Scale calibration
Click the scale readout to enter an imperial scale or 1:N ratio, or press K and draw a known distance; measured quantities update automatically.
- Imperial scale input
- Metric or imperial 1:N ratio
- Known-distance line and quantity recompute
What you'll accomplish
Set a trustworthy page scale from a known drawing dimension.
Steps
- For a printed scale, click the scale readout to open Set scale.
- Choose Imperial and enter formats such as 1/8 in = 1 ft, or choose Imperial/Metric ratio and enter 1:N.
- For a known dimension, press K, click two points, enter the real-world length, and choose ft or m.
- Apply and verify the scale readout and recomputed item quantities.
What to expect
- Invalid distance input remains in the dialog with an actionable example.
- Escape, Cancel, or clicking outside abandons the pending calibration.
- Count items remain each; scale affects measured linear and area items.
- Viewport zoom percentage and page scale are independent values.
