What document types does Armeta support?

Armeta contextualizes the critical engineering documents that industrial facilities depend on: P&IDs (Piping & Instrumentation Diagrams), piping isometrics, PFDs (Process Flow Diagrams), and line lists. The platform handles both graphical drawings and tabular engineering data — scanned PDFs, native CAD exports, historical archives, as-builts, vendor deliverables, and spreadsheet exports — and reconciles them into a single engineering knowledge graph.

Can Armeta contextualize data from piping isometrics?

Yes. Armeta extracts pipe routing, fittings (elbows, tees, reducers, flanges), welds, dimensions, and material specifications from piping isometrics, and generates structured fabrication BOMs and spool-level data for material take-off and fabrication tracking. Isometric data is automatically reconciled against P&ID and line list data through cross-document entity resolution.

Can Armeta process line lists and engineering data tables?

Yes. Armeta parses line list documents and extracts every line-level attribute — line number, size, material spec, insulation, operating and design conditions, from-to connectivity, and P&ID reference. The structured line list data is reconciled against P&ID and isometric extractions so discrepancies between graphical drawings and tabular records are surfaced automatically.

Does Armeta contextualize data across P&IDs, isometrics, and line lists?

Yes. Cross-document entity resolution is the core of Armeta's contextualization engine. The same line number, equipment tag, or instrument identifier is matched and reconciled across every drawing and data table in your archive. A line on a P&ID resolves to its physical routing on the isometric, which reconciles against the line attributes on the line list. The result is a unified, multi-document-type engineering knowledge graph rather than a set of siloed extractions.

Platform

The platform that contextualizes every critical engineering document your plant depends on.

Armeta's contextualization engine reads critical engineering documents — P&IDs, piping isometrics, line lists — from the legacy PDFs your archive actually contains: scanned paper, rasterized CAD plots, faded reproductions that smart-PDF tools can't touch. Purpose-built for industrial engineering. Not a generic OCR. Not an LLM wrapper. The engineering data foundation your facility has never had — from documents you already own.

How it works

Five stages, one engineering knowledge graph.

Every P&ID that passes through Armeta is processed in five stages. Each stage is inspectable, editable, and auditable. Every output is tied to a specific source region in the original drawing — drawing-traceable by design.

Stage 01

Ingest

Bring any document, in any format.

Armeta ingests legacy PDFs and structured files regardless of origin, age, or document type: graphical drawings (P&IDs, piping isometrics, PFDs) and engineering data tables (line lists, data sheets). Scanned paper drawings from decades-old archives, rasterized CAD plots, flat image exports, faded reproductions, spreadsheet exports, and vendor deliverables. The ingest pipeline does not require selectable text, vector layers, or embedded tag data — it reads the legacy documents your archive actually contains. Your entire engineering archive, at scale.

File types: PDF (native + scanned), PNG, TIFF, JPG, XLSX
Batch ingest: Unit- or facility-scale archives
Typical throughput: Hundreds of documents / day

Stage 02

Extract

Symbols, tags, lines, and tabular records.

The extraction engine adapts to each document type. For graphical drawings, it identifies every symbol, tag, annotation, dimension, fitting, and line. For engineering data tables, it parses tabular structure, column semantics, and row-level records. P&IDs yield equipment, instruments, and process connectivity. Piping isometrics yield spools, fittings, welds, dimensions, and fabrication BOMs. PFDs yield process streams and operating conditions. Line lists yield structured line-level attribute data — sizes, specs, conditions, and from-to connectivity.

Document types: P&IDs, isometrics, PFDs, line lists
Configures to: Your symbol library + conventions
Validation: Engineer-reviewed before delivery

Stage 03

Contextualize

Entity resolution across drawings and data tables.

Armeta contextualizes data across document types and formats through entity resolution — the same line number, equipment tag, or instrument identifier is matched and reconciled across every drawing and data table in your archive. A line number on a P&ID resolves to its physical routing on the isometric, which reconciles against the line attributes on the line list. The result is a unified, multi-document-type engineering knowledge graph where graphical and tabular data reinforce each other — and discrepancies between them are surfaced automatically.

Scope: Unit-level or facility-level graph
Reconciliation: Tags and lines across every document
Discrepancies: Surfaced automatically

Stage 04

Compare

Every change between revisions, flagged and auditable.

Armeta compares any two revisions of the same document — P&ID, isometric, or line list — and produces a structured delta: what was added, what was removed, what was modified. Every change is tied to a specific region on the source document and can be reviewed visually, exported as a change report, or fed directly into MOC documentation.

This capability eliminates the “two prints and a red pen” reality of how most operators track drawing changes today.

Output: Structured delta, change report, MOC feed
Traceability: Every change document-region tagged

Stage 05

Deliver

Feeds your engineering systems, IT stack, and digital twins.

Armeta's outputs are consumed via three channels: direct API integration, JSON exports for custom pipelines, or Excel deliverables for non-technical teams. The structured data is designed to feed into the systems your organization already runs — engineering document management, asset databases, digital twin platforms, and compliance software.

Every output is versioned and traceable back to the source document and source region.

The engineering knowledge graph Armeta builds is a living data foundation — it evolves with every document revision, every as-built update, and every new sheet added to your archive. Integrates with any downstream system via API.

Channels: REST API · JSON · Excel
Versioning: Source document + region retained

Purpose-built

Purpose-Built for Industrial Engineering Documents

Armeta is not a generic document intelligence tool. The contextualization engine is purpose-built for the specific formats, symbology, tabular conventions, and domain logic of industrial engineering documents.

It understands the semantic relationships between engineering entities — not just text on a page, but what a tag means, where a line routes, how a spec governs a component, and how a drawing connects to a data table.

And it does not depend on smart PDFs. Most of the industrial engineering archive exists as scanned paper, rasterized CAD plots, and legacy image files — no embedded metadata, no selectable text, no vector layers. Armeta reads them all.

What Armeta reads

Every critical engineering document your facility depends on.

Armeta is not a single-document-type tool. The contextualization engine adapts to each document's format — graphical or tabular — and contextualizes them into a unified engineering knowledge graph.

Drawings

P&IDs

Piping & Instrumentation Diagrams

The master schematic of your process. Armeta extracts equipment, lines, instruments, tags, off-page connectors, and builds cross-drawing connectivity across your entire facility archive.

Piping Isometrics

The fabrication and construction document for every pipe spool. Armeta extracts pipe routing, fittings (elbows, tees, reducers, flanges), welds, dimensions, materials, and generates structured BOMs for material take-off and fabrication tracking.

PFDs

Process Flow Diagrams

The high-level process overview showing major equipment, process streams, and operating conditions. Armeta extracts equipment blocks, stream data, temperatures, pressures, and flow rates.

Data Tables

Line Lists

Tabular engineering records listing every line in a process unit: line number, size, material spec, insulation, operating and design conditions, from-to connectivity, and P&ID reference. Armeta extracts and structures line list data and reconciles it against P&ID and isometric data.

Accuracy and validation

Accuracy you can put in a contract.

Every extraction Armeta delivers is validated by our engineering team before it reaches you. This is not a pass-through of raw model output. It is a deliverable with an accuracy commitment.

Accuracy metrics on your own documents are produced as part of the initial document audit — our ten-document free assessment that establishes baseline performance before any paid engagement.

Visual review of every drawing

Every extracted graph is reviewed by an engineer against the source drawing before delivery.

Statistical accuracy sampling

Equipment, line, and instrument-level sampling against ground truth on every engagement.

Cross-drawing connectivity validation

Off-page connectors reconciled across the full set; dangling references flagged.

Revision delta review

Change reports reviewed against the source drawings before MOC packages are produced.
