About engineering
Engineering Diagram Generator is a skill for creating engineering diagrams in drawio format. It covers electrical schematics, P&IDs, rack layouts, logic gates, fault trees, and PLC ladder diagrams, with guidance on stencil names and symbol colors.
Key features
- 01Creates diagrams in drawio fences
- 02Covers electrical schematics and wiring
- 03Supports P&ID and rack diagrams
- 04Includes logic gate, fault tree, and PLC ladder types
- 05Specifies stencil names and symbol colors
Use cases
- 01Document an electrical circuit or wiring plan
- 02Map a process and its instrumentation
- 03Plan a data center rack layout
- 04Represent logic gates, fault paths, or PLC ladder logic

From the project READMEEngineering Diagram Generator
Quick Start: Choose diagram type → Add symbols from stencil library → Connect with appropriate lines → Add labels/annotations → Wrap in ```drawio fence.
⚠️ IMPORTANT: Always use
```drawiocode fence. NEVER use```xml— it will NOT render as a diagram.
Critical Rules
🔗 This is a drawio-derived skill. All structure, layout, and edge routing rules inherit from drawio SKILL.md. Read the base rules first.
Engineering-specific additions:
- Check stencils/README.md for exact symbol names (e.g.,
mxgraph.electrical.resistors.resistor_1) - Symbol colors: Black(
#000000) for schematic, Blue(#0000FF) for pneumatic, Green(#00FF00) for hydraulic
