Can I measure a PDF floor plan?
Yes. The measurement workspace accepts images and PDF drawings, then lets you calibrate the displayed plan before measuring.
Do I need to know the drawing scale?
Not necessarily. If the drawing contains one reliable known dimension, you can calibrate from that real length instead of manually entering a scale.
Are uploaded drawings saved to my account?
The current measurement workflow is designed to process uploaded plan files in the browser. Export your annotated image separately if you need a permanent copy.
