AI Takeoff

AI Takeoff V2 — how it works

What the takeoff does on its own, what it asks you, and what it never decides for you.

Step by step

  1. Open AI Takeoff from the sidebar. The list shows your takeoffs under three tabs — Active (still running or waiting for review), Done (imported) and Archived.
  2. A takeoff runs in stages you can watch live: it reads the drawings, indexes the sheets, asks in the chat what to take off, measures everything it can without a model (the prepass), then lets the agent review what the prepass produced and flag what it cannot settle.
  3. The prepass is the part that counts and measures: tags, runs, fittings, risers, devices. It costs nothing — no AI credits are spent on measuring.
  4. Credits are spent only while the agent reviews, answers you in chat, or re-runs a sheet. That is why picking the right sheets matters more than anything else you do.
  5. When the run finishes, the job goes to Review: the marked-up sheet on the left, the items and flags on the right. Nothing leaves the takeoff until you import it into an estimate.
  6. A takeoff opens as a chat (the main way in); the layers button beside it opens the visual review — the same job, drawn on the sheets.
  7. Use the row menu on the list to archive a finished takeoff, delete one you no longer want, or compare it with another run of the same job.
Note: Measuring is free. Credits are spent only when the agent reviews, answers you in chat, or re-runs a sheet — so the sheet picker, not the budget, is where you control the cost.
Tip: Close the page once a run starts. It keeps going on the server and you are notified when it is ready to review.
Careful: A takeoff is a reading of a drawing, not a guarantee. Nothing reaches an estimate until you import it, and the number you bid is yours.

Tips

  • Three rules the takeoff never breaks: no geometry means no quantity, the counting side never sees prices, and nothing is shipped as measured when it was not.
  • You can close the page — the run continues on the server and you get a notification when it is ready to review.
  • One takeoff runs per workspace at a time. A second one waits in the queue and says how many are ahead of it.
