Calibrated lines, areas, and counts — grouped, layered, and linked back to the bill. Full undo/redo, deep-zoom tiles for very large drawings, and per-page scales detected from the PDF mediabox.
Open any drawing in your project, calibrate the scale once, and start measuring — every line, area, or count is grouped, layered, and ready to flow into the bill.
PDF mediabox detection sets the scale automatically; manual calibration is one click for scanned sheets.
Line, polyline, rectangle, area, count. Hold ⇧ for orthogonal, Space to pan, Snap for endpoints.
Nested groups (Type A → 3660mm high → measurements). Per-group totals roll up automatically.
Drag a group onto a bill row — qty + UOM populate, the rate decomposes, and the row goes green. The same quantity drives the downstream cost and A1-A3 kgCO₂e roll-up.
Tile worker pre-generates DZI deep-zoom pyramids per page. Pan, zoom, and snap to the smallest gridline without the viewer stalling.
Each layer holds its own stroke colour, fill opacity, and visibility. Stack as many as you need. Full undo/redo on every measurement — no half-states, no broken groups.
Every measurement is an event. Step back through dozens of clicks — no broken groups, no lost work.
Drag a group onto a bill row to push qty + UOM. The row resolves, the rate decomposes, the total updates.
Annotate sheets for the PM. Comments scope to a measurement, group, or sheet — and stay with the drawing.
Calibrate once, measure for hours, land in the bill in seconds.
