Wrap Block Names

You can now wrap block names into multiple lines. In previous versions, a block name had to be shown in one line in a Block, and it wouldn’t allow you to drag a Block to wrap names. In this version, you can finally drag any corner of a Block to change its size.
This makes diagrams easier to read and more visually accessible than before!

Creation of Activities as Blocks in BDD

Effortlessly create Activities as Blocks within Block Definition Diagrams by dragging and dropping an Activity diagram from the structure tree. This process automatically generates Blocks with <<activity>> keyword. The same method applies to other behavior diagrams, including Sequence and Statemachine diagrams. Enhance your navigation experience with the ability to double-click these blocks for instant access to the corresponding detailed diagrams.

Customizable Model Display

Tailor your workspace in Astah System Safety to your specific needs by enabling or disabling model types. With the new ‘facet’ setting, effortlessly configure your environment to display only the models you require, such as STPA and GSN, while hiding others like SysML and SCDL. This streamlining feature, accessible via system properties or project settings, allows you to concentrate on the relevant models, providing a cleaner, more focused interface for your project work.

Improved Usability in State Machine Diagrams:

In state machine diagrams, it is now possible to insert states in the midst of transitions, enhancing the ease of creating and modifying these diagrams.
