Enjoy Refined UI

You can choose your favorite theme from the pre-installed library including dark theme.
Also all the menu and tool icons are renewed that brings a modern look.
Get Astah SysML in the most comfortable look for you and focus on modeling!

Compare and Merge

Work efficiently with your team members

Now you can compare diagrams and models between two files.
You can see the differences visually and intuitively by placing two diagrams side-by-side and also in a list to check details. After comparing diagrams, you can merge changes into one file.


Cameo Systems Modeler Data Import/Export.

You can export all the diagrams you create in Astah SysML to a mdxml file that can be imported to Cameo Systems Modeler (formerly known as: MagicDraw with SysML plugin).
Also you can import data from Cameo Systems Modeler to Astah SysML via both mdxml and mdzip.

Cameo Systems Modeler Data Import/Export

XMI Export

Finally, you can export your model data to OMG XMI 2.5 format file.
This will allow you to exchange model data between different tools.

Enhanced Diagramming Experiences

Enhanced Map View

Map View overlaid on the Editor lets you grasp and change the area you want to see faster.

Swift Objects Insert

Insert new objects by directly dragging them on lines between the objects.

Space Adjustment

[Gap Expander/Remover] tool lets you move multi-objects when inserting new ones.

In-App Script Editor

Access models via Script.

Open Script Editor within Astah SysML. You can easily access models and validate, alter them or anything you’d like to perform. Sample scripts are available so that you can just copy and paste to start!

Improved SysML Compliance

We reworked to provide more compliant modeling environment to OMG SysML specifications.
Now Astah SysML supports SysML Enumeration, Instance Specifications and Links and more.
XMI import/export and profile are also supported.

Note Visibility

Now you can hide Notes from diagram’s context menu.
Notes are very useful when you add comments, additional information to specific models or jog down your thoughts. This new option lets you switch the visibility of Notes on your diagrams with one-click.

Apply Stereotype Icons

Make diagrams go more expressive.

Set Stereotype icons and represent the model elements in them. All you do is to upload image files associated to Stereotypes. So all the models with the stereotype will turn into the defined images.
This visual switch will make your diagram communications go much more clearly.

Astah SysML Profiles

Line Jumps

Make your diagrams less complex.

Line-jump expression is now available. In complex diagrams with many connecting lines, the jump expression at the intersection will lead you through to help you get the connection points more easily.

License/ Project file format change 

Both license file format and project file extension will change since version 8.0 as shown below:

[table “142” not found /]

Customers who have valid licenses will need to get a new license file to use version 8.0. Please read the page below for details:
