Measure areas, lengths and counts straight off PDF drawings, with the scale read from the drawing, snapping to the
drawing's own lines, and a measurement sheet in the house format (Nos × L × W × H, decimal feet, deductions as their own rows).
Your drawings stay on this computer. PDFs and takeoffs are saved in this browser's storage (IndexedDB) on this device only —
nothing is uploaded, and another browser or computer will not see them. Use Export → Project + PDFs to move a takeoff with its drawings in one file (Project (.json) carries the measurements only; a PDF added again
is checked against the drawing it was measured on, by its content, not its name). Vector PDFs exported from CAD snap to their lines; scanned PDFs can be measured but do not snap.
