P&IDs (piping and instrumentation diagrams), 2D engineering drawings, and 3D CAD models contain essential design information—from equipment tags and dimensions to connections, notes, and specifications. Much of this information still has to be interpreted, transcribed, and checked manually before it can be used in downstream systems.
Our approach combines drawing recognition, engineering specifications, and rule-based processing to connect drawing interpretation, structured extraction, design calculations, and CAD generation. Engineers review uncertain or critical results before they are used in design or production.
Turning drawing information into usable engineering data is still labor-intensive.
- Manual interpretation and data entry
Extracting tags, dimensions, line numbers, and annotations into spreadsheets or design systems takes substantial engineering time. - Connectivity cannot be captured by OCR alone
Understanding how equipment, piping, signals, and dimensions relate requires more than recognizing individual text and symbols. - Design rules extend beyond the drawing
Specifications, legends, formulas, engineering standards, and past design decisions must be considered alongside the drawing. - Results must be traceable and verifiable
Information used for design, procurement, and quality assurance needs clear source references and checks against applicable rules.
Combine drawing understanding with engineering rules and verification.
- Identify drawing elements and their relationships
Recognize equipment, piping, symbols and connections in process diagrams. In mechanical drawings, connect dimensions and notes with the design elements they describe. - Convert extracted information into structured data
Organize equipment, piping specifications, fluids, insulation, signals, and design dimensions into data structures that support procurement, installation planning, and engineering calculations. - Apply specifications and engineering logic
Use legends, technical specifications, design formulas, and explicit engineering rules to interpret information that is not stated directly in the drawing and to identify missing design conditions. - Support parametric design and CAD generation
Use validated dimensions and agreed design rules to support calculations and generate or update CAD models and drawings where the target system permits. - Flag exceptions for engineering review
Identify low-confidence extraction, missing specifications, inconsistent tags, or potential rule violations. Engineers can verify these items before the resulting data or designs are approved.
Reduce repetitive drawing work while retaining engineering control.
- Faster material and equipment takeoff
Create structured equipment and specification lists from relevant P&IDs and drawings.
- Less manual transcription
Transfer validated drawing information into downstream engineering workflows.
- More consistent design checks
Use explicit specifications and rules to help identify omissions and inconsistencies.
- Easier reuse of prior designs
Find and compare related drawings, components, and design patterns.
- A practical path to design automation
Connect document understanding to calculations, human review, and CAD workflows.
From reading drawings to supporting verifiable design decisions.
Design automation requires more than extracting text from images. By connecting drawing elements and their relationships to specifications, calculation logic, and engineering review, Technica AI helps organizations turn existing drawings into structured information and more repeatable design workflows.
