Find the P&ID information you need and review connections and results faster.

SURRO DrawAX combines AI-powered P&ID digitization and data extraction with drawing validation. It converts symbols, text, piping lines and their connections into data engineers can search, check against registered rules and share.

01 · Upload Drawings

Upload PDFs and Scans as They Are

Add PDF or scanned P&IDs to a project to begin AI recognition. Keep revisions of the same drawing together and identify the latest version.

Extract information from the uploaded drawing

02 · Extract Drawing Information

Reduce Manual Checks of Symbols, Text and Piping

AI-driven P&ID data extraction identifies symbols such as valves, pumps and tanks, reads text such as line numbers and equipment names, and extracts piping lines. Engineers can review the results directly on the original drawing.

Build connection data from the recognized objects

03 · Map Connections and Search

Find Equipment and Trace Its Connections

Trace piping to map from/to connections between equipment, lines and instruments. Search for objects and tags, then review their attributes and connections together. The resulting structured data supports drawing analysis and change-impact reviews.

04 · Set Review Rules

Make Your Team’s Review Rules Reusable

Select the objects to inspect and save your internal drawing review criteria as reusable rules. Share the rules across your team and record which ones were used for each check.

05 · Run Checks and Review Results

Apply Your Rules and Review Flagged Issues

Run automated P&ID checking against your saved rules and review results that do not meet them. Engineers can inspect recognition results and P&ID validation issues on the drawing, correct misidentified or missing items, and open flagged locations to compare them with the original.

06 · Share Results and Reuse Data

Put Drawing Data and Review Results to Work

Add review comments to drawings and share the reviewed results in PDF reports. Export equipment, line and valve lists, along with source data for material takeoff (MTO), to Excel. Publish validated structured data in formats such as CSV and JSON for downstream integration.

Work from Shared Drawing Data and Track Reviews

Manage access for each project and drawing, and track source locations and review history. Work from the same P&ID data and review rules to share results and support drawing changes and downstream work.

Engineers’ review results can become labeling data for improving recognition models. In Truss AI, connect labeling, QC review and approval with model performance management to maintain recognition quality for your organization’s drawings.
