Turning P&IDs into Structured, Actionable Intelligence

Process & Instrumentation Diagrams (P&IDs) are the backbone of industrial engineering—but they’re also dense, complex, and traditionally locked in unstructured formats. DigitalSketch.ai Intelligent Symbol Recognition changes that by applying advanced AI vision and contextual reasoning to automatically interpret P&IDs with exceptional accuracy.

Our AI-powered engine doesn’t just “see” symbols—it understands them.

From Visual Symbols to Structured Data

DigitalSketch.ai automatically detects and classifies P&ID symbols across the entire diagram. From pumps, valves, and filters to instruments, lines, and connections, every element is identified and contextualized to enable reliable data extraction and downstream automation.

This means engineering teams can move beyond manual interpretation and unlock digital workflows directly from legacy drawings.

Core Capabilities

? Automatic Symbol Detection & Classification

Our models are trained specifically on industrial P&IDs, enabling accurate recognition of:

1. Valves, pumps, vessels, and equipment
2. Instruments such as pressure, flow, level, and differential indicators
3. Piping components, reducers, vents, drains, and fittings

Each detected symbol is classified with its correct instrument or equipment type, not just a generic label.

? High-Accuracy Bounding Box Generation

Every identified symbol is localized using pixel-precise bounding boxes, ensuring:

1. Accurate spatial placement on large, high-resolution drawings
2. Reliable association with nearby tag numbers, line sizes, and annotations
3. Visual traceability between AI results and the original diagram

This precision is critical for validation, audits, and downstream machine workflows.

? Relationship Mapping Between Components

Unlike traditional OCR or symbol detection tools, DigitalSketch.ai goes further by mapping relationships across the P&ID:

1. Instruments linked to the equipment they measure or control
2. Valves associated with specific lines, sizes, and service
3. Filters connected with upstream/downstream indicators

For example, a differential pressure indicator is not only detected—but also correctly associated with the filter it measures, creating true engineering context.

Why Intelligent Recognition Matters

By combining symbol recognition, spatial reasoning, and contextual understanding, DigitalSketch.ai enables:

1. Faster P&ID digitization and modernization
2. Higher confidence in extracted engineering data
3. Reduced manual effort and interpretation errors
4. A foundation for digital twins, asset models, and AI-driven operations

Built for Industrial Scale

Whether you’re processing a handful of drawings or thousands of legacy P&IDs, DigitalSketch.ai is designed for industrial-scale accuracy, consistency, and explainability—bridging the gap between engineering diagrams and intelligent digital systems.

DigitalSketch.ai Intelligent Symbol Recognition transforms static P&IDs into structured, connected, and machine-ready intelligence—automatically.
