engineering

Original：🇺🇸 English

Translated

Create professional engineering diagrams using drawio XML format with industry-standard symbols. Best for electrical schematics, P&ID (Piping & Instrumentation), rack diagrams, fault tree analysis, PLC ladder logic, and logic gate diagrams. Built on drawio with engineering-specific stencils. NOT for simple flowcharts (use mermaid) or network topology (use network skill).

Engineering 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
```drawio
code 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
