How it works
From a drawing set to a cited review.
DC Copilot reads each sheet for what it's authoritative on, measures the design from the vectors, then tests it against the published standard — and shows its working on every finding.
Upload a vector PDF
A drawing set, not a scan. The engine works from the vector geometry — walls, dimension strings, title blocks — so it can measure, not guess.
Triage sorts the sheets
Each sheet is classified by its drawing name — floor plan, sanitary schedule, interior elevations, details. The proposed plan is told apart from the demolition plan, so the right sheet feeds each check.
Read by authority
The layout comes from the plan, the fixture counts from the schedule, the mounting heights from the elevations. Each fact is taken from the sheet that's actually authoritative on it — never blended into a guess.
Measure deterministically
Room sizes are derived from the vector walls and the drawing scale, validated against the dimension strings on the sheet — not from the AI's freehand estimate.
Test every requirement
The engine runs each rule in the requirement library against the read design and reconciles the sheets against each other, flagging where they disagree.
A cited report
Findings come back grouped — must-fix, meet-where-practicable, review, pass — each with the verbatim clause and reference. You confirm each one and decide.
Read by authority
Each fact from the sheet that owns it.
A single AI pass over a whole set blends everything into one stochastic answer. DC Copilot instead takes each fact from the sheet that is authoritative on it, then reconciles them — so a count comes from the schedule, a height from the elevation, and a size from the measured plan.
Citation-first
The AI reads. The engine rules.
The language model's only job is to read the drawings. The compliance logic is deterministic code that tests each requirement — so a finding is never an AI opinion. Every one is pinned to a verbatim clause and reference you can check against the source in seconds.
Stage-aware
Checked to the stage you're at.
Concept, preliminary or developed — each requirement knows when it can fairly be assessed. You won't be failed for detail you haven't drawn yet, and you'll see what still needs to be shown as the design develops.
