Quantity takeoff from PDF drawings
Measure straight from the drawing set. Quantities update when a scale changes, and totals roll up by room, layer or subject.
What you can do
- Calibrate from a known dimension, or set separate scales for details on the same sheet
- Length, polylength, area, perimeter, volume, count, diameter and arc measurements
- Room fill: click inside a room and its outline becomes an area
- Symbol search: box one symbol and find every one like it, then count them
- Unit costs, formula columns, assemblies and an Excel export or a live link for spreadsheets
Measurements you can trust
A measurement is never stored as a number — it is the geometry times the sheet’s scale. Fix a wrong scale and every quantity on that sheet updates.
From quantity to cost
Add unit costs and formula columns, group measurements into assemblies and export a priced takeoff to Excel. Quantities can be grouped by room so a takeoff reads like the building.
