What is SysML?

SysML stands for Systems Modeling Language. It is a general-purpose modeling language for systems engineering applications. SysML is based on UML with some modifications. It supports the specification, analysis, design, verification, and validation of numerous types of systems and systems-of-systems (e.g. software, processes, information, and facilities).

Supported SysML diagrams

The SysML tool supports the following diagrams:

  • Activity diagram
  • Sequence diagram
  • State machine diagram
  • Use case diagram
  • Block definition diagram
  • Internal block diagram
  • Parametric diagram
  • Package diagram

SysML Model Overview

The SysML modeler allows you to navigate the model through the relationships. The Model Navigator feature helps you to understand model relationships better. It also includes the Element Browser that will show you all the elements in a table. Element Matrices show elements and their mutual relationships.

Element Reuse

The SysML tool maintains a complete model with all entities and their relationships within a project. The backend model allows you to use an element on multiple diagrams. When you edit an instance of an element, all other instances on all diagrams in the project will be updated.


Our SysML software allows you to generate documentation based on your SysML diagrams and models. You can save the documentation to DOCX, PDF, RTF, ODF, or HTML.


You can use style sets with various styles that allow you to visually emphasize elements by their meaning, similarity, common domains, or any rules you will consider appropriate for the given situation.

Export to Imaging Formats

You can share your SysML diagrams and models with others. The project or its part may be exported to various imaging formats - bitmap (PNG, JPG, BMP, GIF) and also vector (SVG, WMF, EMF).
