Drawing Generation Pipeline
All drawing types share a six-step SVG generation pipeline:
Step 1: Layout Grid
Set up a coordinate system based on paper size and scale:
Paper: A1 (841x594mm at 1:50 scale -> drawing area covers 42m x 29.7m real-world)
Grid: 10mm base grid for component snapping
Margins: 20mm all sides, 50mm bottom for title block
Origin: Top-left at (20, 20)mm
Standard paper sizes:
A3: 420x297mm -- Small systems, detail drawings
A1: 841x594mm -- Standard engineering drawings
D: 864x559mm -- US D-size (ANSI D)
E: 1118x864mm -- Large systems, overall layouts
Standard scales: 1:20, 1:50, 1:100, 1:200, 1:500, NTS (not to scale)
Step 2: Component Placement
Place symbols from the symbol library at specified coordinates:
// Reference the ISA-5.1 library (from references/symbols/symbols-pid.ts)// or IEEE library (from references/symbols/symbols-electrical.ts)import { PID_SYMBOLS } from'./references/symbols/symbols-pid.js';
import { ELEC_SYMBOLS } from'./references/symbols/symbols-electrical.js';
constsymbol = PID_SYMBOLS['centrifugal-pump'];
// Place at grid coordinate with optional rotationconst placed = placeSymbol(symbol, { x: 150, y: 200 }, { rotation: 0 });
Step 3: Connection Routing
Route pipes and wires between components with automatic bend detection:
Pipes: Horizontal/vertical runs with 90-degree bends. No diagonal runs on P&IDs.
Wires: Same orthogonal routing. Use junction dots at T-connections.
Line weights: Process pipe (2px), instrument lines (1px), electrical (1.5px)
Line styles: Process (solid), instrument (dashed), electrical (dot-dash per ISA)
Step 4: Dimensions and Annotations
Pipe sizes along each run: 3" SCH 40 CS (3-inch Schedule 40 carbon steel)
Equipment labels: Tag numbers above symbols (P-101, HX-201, T-301)
Instrument balloons: Circle with tag number, line to instrument connection
Flow arrows: Filled triangles on process lines indicating flow direction
Step 5: Title Block Generation
import { TitleBlock } from'../../types/infrastructure.js';
consttitleBlock: TitleBlock = {
projectName: 'Data Center Cooling System',
drawingNumber: 'P&ID-001',
revision: 'Rev. A',
date: '2026-02-27', // ISO 8601drawnBy: 'Claude (AI-Assisted)',
checkedBy: 'VERIFY WITH LICENSED PE', // ALWAYS this value -- non-configurablescale: '1:50', // or "NTS"sheet: '1 of 3',
};
Title block occupies bottom 50mm of drawing. PE disclaimer printed in title block as non-removable text element.
Step 6: SVG Output

Connection routing algorithm:
For orthogonal pipe routing between two points (x1,y1) and (x2,y2):
If delta-x > delta-y: route horizontal first, then vertical (L-shape)
If delta-y > delta-x: route vertical first, then horizontal
If points share x or y coordinate: direct line
For complex layouts: use intermediate waypoints to avoid equipment conflicts
Mark T-junction with filled circle (3px radius) where pipes cross a connected run
