About

Diyi does one thing: turn structural steel drawings into a bill of materials where every number states where it came from.

What we don't do#

• No general-purpose drawing recognition. Structural steel only.
• No "one click, use as-is". Takeoff output must be reviewed; what we do is make that review feasible —

from checking 142 rows down to checking 3.

• No hand-written rules for how the model should read a drawing. We tried; whole classes of members went missing.

How it works#

The model decides for itself what to render and at what zoom, whether to read the schedule first or the plan, whether to write a script to pick out column tags by colour. We take care of three things:

1. A clean environment — every job runs in a sandbox; one account's job cannot reach another's files.
2. A full record — every round of reasoning, every command, its output and every crop it looked at is kept and replayable.

When a number looks wrong, you can go back to the exact crop it came from.

1. Settlement per round — usage is charged as the job runs, not back-filled at the end. If the balance can't cover the next

step the job saves itself and pauses; after a top-up it resumes where it stopped, nothing is burned.

What you get#

Every job produces files you can use straight away:

• BOM.xlsx — the bill of materials, each row stating its section basis and quantity basis
• model.dxf — a 3D wireframe model
