Astah SysML
SysML Modeling Tool for Systems Engineering
Design complex systems faster with Astah SysML – a standards-compliant modeling tool for MBSE.
Trusted by leaders in aerospace, automotive, and embedded systems engineering.
What is Astah SysML?
Astah SysML is a powerful modeling tool based on the SysML standard, designed for Model-Based Systems Engineering (MBSE).
It enables teams to design, analyze, and document complex systems across domains such as aerospace, automotive, and embedded systems.
All the SysML Diagrams You Need
Astah SysML provides full support for all SysML diagram types, enabling precise, standards-compliant system modeling.
Included diagram types:
Team Development
Compare and Merge Models
Astah SysML empowers team modeling by allowing multiple engineers to work on the same project.
Use the compare and merge feature to identify differences between two versions of a model file and integrate them.
Differences can be reviewed visually through side-by-side diagrams or in a detailed table format
– ensuring you never miss a change.
Model Smarter:
Perfect for both new and advanced users
Astah SysML is packed with assistive features that accelerate your modeling.
With functions like auto-alignment guides, multi-object creation from text, and one-click actions,
you can build professional diagrams in record time.
Use the gap expander/remover to tidy layouts, and quickly search and replace elements — all designed for speed, precision, and clarity.
Experienced Systems Architects can use scripting language to access the models.
Interoperability
Works with Cameo Systems Modeler
Export the diagrams you create in Astah SysML to a variety of formats, including image files
such as JPG, PNG, EMF, and SVG as well as XML formats like OMG XMI 2.5 and
MDXML that are compatible with Cameo Systems Modeler (formerly known as: MagicDraw with SysML plugin).
You can also import model data from Cameo Systems Modeler into Astah SysML using MDXML and MDZIP files.
Endorsement
SysML is already the industry standard for engineering large, complex systems; more safety and quality system development teams are rapidly adopting the language every day.
Now every engineering specialty, from mechanical, to electronic to software engineering have a common language to design safe, complex systems architectures. We are pleased to welcome Astah to the fold, a unique modeling tool from Japan, from Change Vision.
