Solution pattern · not a customer claim
When an engineering drawing becomes a data source.
The pattern shows how symbols, tags, and topology can be extracted from P&IDs and engineering diagrams, linked to evidence, and reviewed professionally.
Starting point
OCR reads characters. Engineering needs relationships.
A tag alone is not yet asset knowledge. The information becomes operationally useful when components, lines, and connection points exist as reviewable relationships.
System boundary
Extraction proposes. Specialists approve.
Safety-critical changes, sizing, compliance assessment, and machine control do not originate from unreviewed results.
Architecture
Four steps that retain evidence.
Every extracted element and relationship remains linked to the relevant diagram section.
- 01
Protect the input
PDFs, scans, images, or CAD exports remain versioned and follow existing role permissions.
- 02
Combine signals
Layout, symbols, text, lines, and connection points are evaluated together.
- 03
Build topology
Detected elements become a graph with references back to the source.
- 04
Approve professionally
Uncertain or critical elements enter review before transfer to target systems.
