Aggiornamenti in v11.0

Funzionalità

    • Enabled setting responsible elements by dragging models from the Structure Tree onto Partitions.
    • Enabled setting types by dragging and dropping models from the Structure Tree onto diagram elements that support type assignment.
  • Partition Enhancements: Added the ability to display Partition names even when a responsible element is assigned, and enabled on-diagram editing for names and responsible elements.
  • Added a separator to the diagram creation menu.
  • You can now individually choose which stereotypes to display on the diagram.
• SysML & Specialized Modeling
  • Model Import: Added support for importing Cameo Systems Modeler 2024x models. (#10159) - Cameo XMI Import.
  • Excel Export: Added a “Save as a new template” button to the [Export Requirements to Excel] dialog that opens from [File] – [Export] – [SysML Requirement Table to Excel].
  • GSN/SCDL/STPA:Added support for Assurance Claim Point (ACP).
  • Performance: Improved performance for the “Show Related Elements” feature.
• Mindmap Improvement: Refine your Mind Maps instantly. Added a dedicated button to the toolbar on Mind Map so you can switch topic shapes – simple plain or bubble – with a single click.
  • Enabled element deletion (such as Mind Map Topics) using the Backspace key.
  • Enabled reordering of Mind Map elements, images, and common diagram elements.
• API & Documentation
  • Manual Updates:
    • Added instructions for the “Align Constraint Parameters” feature.
    • Updated Model conversion documentation to address existing deficiencies.
  • API Enhancements:
    • Enabled retrieval of BoundRect for non-SysML diagrams.

Correzioni

• General Stability
  • Fixed an exception that occurred during plugin initialization.
  • Fixed an exception that occurred when creating a new project immediately after a search.
  • Fixed an issue where projects could fail to open in certain specific cases.
  • Fixed a bug on macOS where types starting with “S” could not be selected correctly in the Property View.
• Diagramming & UI
  • Sequence Diagrams: Fixed an issue where “Create Messages” could fail or cause exceptions.
  • Labels & Styles:
    • Fixed an issue where text colors were not copied when using “Copy Style.”
    • Enabled text wrapping for Combined Fragment guards and Constraint Parameter name labels.
    • Fixed a bug where curved lines took selection priority over their labels in SysML diagrams.
    • Fixed an issue in the Property View where it was not possible to switch to a model element of the same name if it belonged to a different namespace.
    • Fixed an issue where stereotypes applied from a profile were ignored upon loading when packages were nested in multiple levels.
    • Fixed an issue where the Constraints compartment was automatically displayed when a constraint was added to a ValueType.
    • Fixed an exception that occurred when performing stereotype-related operations in projects where unused profiles were applied.
  • Project Management / UI:
    • Fixed an issue where SysML-specific configuration items were missing from the Project Settings.
  • Project Property Settings
    • Fixed an exception that occurred when clicking the “OK” button in the Project Settings dialog.

  • Element Behavior:
    • Fixed an issue where operations in the Structure Tree were occasionally executed on unselected models.
    • Adjusted the initial editing state of property elements immediately after creation in Internal Block Diagrams and Parametric Diagrams.
    • Prevented the automatic display of the corresponding compartment (such as the Constraint compartment) when adding elements like constraints from outside the diagram (e.g., via the Structure Tree or Property View).

    • Fixed an issue where selection handles (knobs) were not displayed after moving common diagram elements by dragging them with the mouse.
    • Corrected line type rendering for automatically generated line presentations.
    • Fixed a bug in the Structure Tree where only a single element could be moved when dragging multiple selected items, depending on the selection method.
• Export & Integration

  • Fixed resolution issues when exporting tables as images.
• API
  • Fixed an issue where moving Blocks, Actions, or States via the API could cause attached Ports or Pins to shift to a different edge.
  • Fixed an exception that occurred in the API IParameter.getTypeExpression() when a parameter had no type set.
  • Fixed an issue where the type was not correctly reflected when creating a Flow Property via the API.
