Frequently asked questions
Why calibrate each page?
Sheets can have different scales. Calibration uses a known length to convert measurements on that page.
Can I measure details at different scales on one page?
Each page uses one scale at a time. Recalibration updates all saved measurements on that page. Put details on separate pages to retain measurements from multiple scales.
How do I keep my takeoff?
Measurements are held for the current session. Download the CSV before closing the page or opening a different plan.
