Interactive Diagrams, also known as “Custom Diagrams”, are a newer generation of visualization tools that provide enhanced interactivity and customization beyond the capabilities of legacy diagrams.

​
Overview

Interactive diagrams are built using modern web technologies and can provide:
  • Real-time parameter updates
  • Interactive elements (zoom, pan, click)
  • Custom animations and transitions
  • Complex geometric visualizations
  • Industry-specific diagram types

​
Key Differences from Legacy Diagrams

​
Development Workflow

Interactive diagrams are developed in separate GitHub repositories and then compiled for use in ClearCalcs templates.

​
Repository Structure

│   │   ├── interface.ts
│   │   └── ...

​
Development Setup

First Time Setup (Mac):
  1. Install brew: https://brew.sh/
  2. Run brew install npm in terminal
  3. Clone the diagram repository
  4. Run git pull to get latest version
  5. Navigate to /static or /interactive folder
  6. Run npm install

​
Build Process

# 1. Update repository
git pull

# 2. Navigate to diagram folder
cd /static  # or /interactive

# 3. Install dependencies
npm install

# 4. Compile diagram
npm run-script compile

# 5. Output files:
# - Static: /dist/compiled.js
# - Interactive: output/index.html

​
Implementation in Templates

Interactive diagrams are implemented using the diagram widget with custom types: 
{
    "type": "sheetTemplateWidgets", 
    "attributes": {
        "type": "diagram",
        "diagram": [
            {
                "type": "custom",
                "src": "path/to/compiled.js"
            }
        ],
        "equation": [
            {
                "result": "{
                    diagramType: \"splice_atlas\",
                    param1: value1,
                    param2: value2,
                    // ... other parameters
                }",
                "condition": "@default"
            }
        ],
        "referenceId": "custom_diagram"
    }
}

​
Multiple Diagram Types

Some repositories contain multiple diagram types, distinguished by the diagramType parameter: 
{
    // Atlas Tube splice diagram
    diagramType: "splice_atlas",
    memberType: "tube",
    dimensions: tube_dimensions
}

// or

{
    // Atlas Tube bracket diagram  
    diagramType: "bracket_atlas",
    bracketType: "corner",
    loads: applied_loads
}

Data Flow Architecture

​
Shared Components

Interactive diagrams leverage shared components for consistency:

​
SVG Extensions

  • Custom SVG elements specific to ClearCalcs
  • Reusable geometric shapes and annotations
  • Standardized styling and behavior

​
Utility Functions

  • Helper functions for calculations and transformations
  • Common geometric operations
  • Data formatting and validation

​
Asset Library

  • SVG images for standard components
  • Icons and symbols
  • Material representations

​
Testing and Development

Testing Setup:
  1. Run npm start to start development server
  2. Run npm test in a separate terminal
  3. Both must be running simultaneously
  4. Pass diagramType parameter in test calls
  5. Select diagram type in dropdown when testing

​
Best Practices

  1. Version Control: Always work from the latest repository version
  2. Testing: Test thoroughly before uploading to template builder
  3. Documentation: Document parameters and behavior changes
  4. Performance: Optimize for rendering speed and responsiveness
  5. Consistency: Use shared components when possible

​
Example: Atlas Tube Diagrams

The Atlas Tube custom diagrams provide a comprehensive example of interactive diagram implementation:
  • Repository: custom-diagrams-library
  • Multiple Types: Splice and bracket diagrams
  • Complex Geometry: Parametric tube connections
  • Industry Specific: Tailored for structural steel connections
Interactive diagrams are powerful tools for creating highly specialized visualizations. While they require more development effort than legacy diagrams, they provide unmatched flexibility for complex engineering visualizations.
Interactive diagrams require JavaScript/TypeScript development skills and ongoing maintenance. Consider using legacy diagrams for standard visualizations and reserve interactive diagrams for cases requiring unique functionality.
