Select an area on the drawing — the AI engine reads the legend and elements visible in that region and generates a takeoff for only what's there.
Click “Select area on drawing” then drag a box over the part of the drawing you want to analyse.
Configure settings and click Calculate.
AI will generate a detailed cost breakdown.

Quick build
1. Add the PDF drawings — plans, structural and foundation plans, sections. Each sheet is read and coordinated by itself: floor, levels, grid, sizes, E/N.
2. When it says Ready, press Build. Change something only if you know it is wrong.
2. When it says Ready, press Build. Change something only if you know it is wrong.
Steps 1–6 below are for checking and fine-tuning.
1Drawings
Plans, structural GAs, foundation plans, sections. Each sheet's floor is found from the drawing — change it in the list if needed.
2Levels
NameLevel (m)Slab t
Levels and which sheet is which floor are filled in from the drawings as you add them. The more sheets you add (sections, GAs, schedules), the more it knows. Change anything — your edits are kept.
3Coordinates
Click Pick, then click a grid intersection or setting-out point on the drawing.
4Auto-detect
Works on scans and CAD PDFs where walls/columns are filled. Anything missed can be drawn with the toolbar.
5Build from what's there
6Model
Model from drawings
Add plan PDFs → set levels → click two known points → detect → open as a coordinated IFC.

PDF Table Extractor
Pull tables out of PDF schedules (manholes, pipes, setting-out, door/window schedules) into Excel. Works on PDFs exported from CAD or Office, not on scanned images.

Coordinates to CAD
Turn a list of points (ID, Easting, Northing, Level) into a DXF you can open or insert in AutoCAD / Civil 3D, an AutoCAD script, or a Civil 3D PNEZD point file.

Site Calculators
Quick checks for drainage, setting out and quantities.
Pipe gradient
Find downstream invert
Join: bearing & distance between two points
Polar: set out a point from a station
Whole-circle bearings measured clockwise from grid north. Works in any grid (OSGB, Stereo 70, site grid).
Concrete volume
Scale converter
Type in either box; the other one updates. Remember the drawing must be printed at its true paper size (A1 at A1, not fit-to-page).
