For quantity surveyors & estimators
Measure the drawing, not the picture of it.
Give hYYa your AutoCAD .dwg or .dxf and it measures a full take-off from the drawing’s own geometry, broken out by service using the drawing’s real layers — wall runs, enclosed areas and exact equipment counts, straight into a working Excel sheet.
Only have a PDF? An issued PDF is nearly always plotted in black, and black line-work carries no service — so a PDF gives you whole-drawing totals, measured from the drawing’s real geometry at the scale you set, and the CAD file is what gives you a take-off split by service. hYYa states which of the two you got, on the sheet itself.
Every quantity is a draft to check before tender. hYYa shows the basis for each one and says plainly what it could not measure. On CAD, coordinate fidelity is verified — 581 dimension entities across three real AutoCAD drawings, measured at 0.000 mm. A multi-page PDF is taken off in full, with a per-sheet column; any sheet drawn to a different scale is named and left out rather than measured wrongly.

Per-layer lengths, from the geometry
Ask for a layer and hYYa sums its real run length off the drawing's own coordinates — not scaled off an image, not estimated by eye. Wall layers collapse parallel faces to a true centreline instead of double-counting the line-work.
Exact block & equipment counts
Counts come from the block definitions, including blocks nested inside other blocks — so a fixture placed through three levels of reference still counts once, correctly.
Curves measured, not shortcut
A curved pipe run reports its true developed length; ellipses are tessellated exactly. Anything hYYa cannot measure — a SPLINE, for instance — is counted and declared on the take-off with a ⚠ Coverage line, never dropped silently.
One click to Excel or CSV
The whole take-off exports as a working spreadsheet, every row carrying its basis — plan-projected, gross, centreline — so a reviewer can see how each quantity was reached. Watermark-free on either paid plan.
Units confirmed, never guessed
A drawing's units come from the file itself. If they are ambiguous, hYYa asks you to confirm millimetres or metres rather than assuming — because mm-versus-m is a 1000× error on every quantity in the take-off.
Share the lens with your team
On either paid plan, a drawings lens can be shared with up to 10 people, so the take-off, its basis and its notes live in one place instead of in someone's local file.
Which drawings it reads
What it does not do
It does not compare revisions — diffing rev B against rev C is not here yet. It does not price anything; it measures. It does not deduct openings from gross areas, and a named wall layer may include both external and internal walls, so read the basis on each row. And it is an AI draft: check it against the drawing before it goes into a tender. Anything hYYa could not measure is printed on the take-off rather than quietly left out.
Included on every plan
Take-off is not an add-on and never has a separate price — it draws from your plan’s credit allowance like everything else. If drawings are your day job, both paid plans give you the same tools — binary .dwg support, watermark-free Excel, whole-corpus reasoning across a project’s paperwork, and a shared lens for your team. Pick Cloud On-Demand if the work comes in bursts and you would rather buy credits for a job than hold a subscription, or Cloud Ultra if you are measuring most weeks and want an allowance that renews itself.
