The HTML Export feature allows you to transform your engineering models into an interactive, browser-based format. This is the most effective way to share your architecture with stakeholders, clients, or team members who do not have an Astah license.

Browsing the Exported Model:

The exported HTML provides a professional, intuitive interface for project visualization:

  • Sidebar Navigation: Displays your entire model and diagram hierarchy in a familiar tree structure.
  • Details Panel: Clicking any element in the sidebar instantly reveals its properties and related data in the main view.
  • Zero Footprint: Recipients can view the full model on any modern browser without installing additional software.

  • Filtering:
    • The built-in search box allows users to find specific elements using a powerful query syntax:
      <query> or type=<filterType> <query>.
    • Example filters:
      • Diagrams: Filters diagram-related items (e.g., block_definition_diagram).
      • Tables: Filters table-related items (e.g., requirement_table).
      • Specific Types like block, package, or use_case.
