Send your takeoff to Excel or CSV in one click.
Text, callouts, stamps, signatures, clouds, arrows, and custom tools — annotate like you would on paper.
Length, area, volume, perimeter, angle, and true diameter/radius geometry — not approximations.
Autosave, local backup, and cloud project save so you never lose work on a refresh.
