SysModeler — User Manual

1. Introduction

SysModeler.ai is an AI-powered, cloud-based systems-modeling environment built around the SysML (Systems Modeling Language) standard. It gives engineering teams a single place to design, document, analyze, version, and collaborate on complex system architectures — the way a modern cloud based code editor lets developers work together, but purpose-built for systems engineering.

SysModeler supports two modeling paradigms, and you choose one per project at creation time:

SysML v1 (Visual)SysML v2 (Code-Based)
StyleVisual, drag-and-drop diagramsCode-first (textual) with a live, auto-generated diagram
Best forClassic diagram-driven modelingText-based, version-controlled, large-scale models
Primary editorDiagram canvasLSP code editor + synchronized graphical canvas
Version control—Full Git-style branching, commits, and merges
AvailabilityStandardAvailable to organization accounts (arranged via sales)

Everything in SysModeler is real-time and collaborative: multiple engineers can open the same project, see each other's presence and (in v2) live cursors, and edit together without overwriting one another. A built-in AI Agent is embedded directly in the workspace to draft, modify, and explain models from natural-language prompts.

1.1 What you can do with SysModeler

  • Build the full range of SysML v1 diagrams — BDD, IBD, Use Case, Sequence, Activity, State Machine, Requirement, Package, and Parametric.
  • Author SysML v2 models as code, with real-time syntax checking, auto-completion, symbol navigation, and a diagram that regenerates automatically from your text.
  • Collaborate live with your team, complete with presence indicators, shared cursors, and edit-locking to prevent conflicts.
  • Use Git-style version control — commit history, side-by-side diffs, branches, merges, and interactive conflict resolution.
  • Query your model with a database-like Model Query Engine and jump from results straight to the canvas.
  • Trace, filter, and export requirements to ReqIF, CSV, Excel, Word, and Markdown.
  • Drive SysML v2 projects programmatically through REST APIs with scoped API keys (Google Colab, Google Sheets, Python, CI/CD).
  • Export diagrams in PDF and PNG formats for V2 and V1 diagrams can be exported in PDF, PNG, SVG, and XMI formats.
  • Give superusers an Executive Dashboard with enterprise KPI visibility.
