Capella 1.2.0


Capella 1.2.0 is based on:

  • Eclipse 4.6.3 (Neon.3)
  • Kitalpha 1.2.0
  • Sirius 5.1.0

Projects migration

Migrate your Capella projects created with Capella 1.1.x to Capella 1.2.0.

Embedded documentation

Capella 1.2.0 documentation is available inside the workbench (Help menu). The documentation has been reviewed and updated.

New features

Usage monitoring support

A new preference is available to activate a logger named "Usage Monitoring". This logger is aimed to track Capella usages (Project creation, ...). Information are kept in a log file named "Usage.log". The goal is to provide metrics (e.g. which features are used) and later, measure related performances. Only a short list of commands are tooled up in order to reduce performance impacts:

  • Open Session
  • Close Session
  • Create Representation
  • Open Representation
  • Transition
  • Validation

If this file reaches the size of 20 MB, another file is created. The maximum number of files is 30. If this limit is reached, the first file is destroyed. By default, these files are generated into the current workspace. This functionality is activated by default and can be deactivated via the dedicated preference page.

Capella based on Eclipse Neon

Capella 1.2. is based on a stable Eclipse Neon 4.6.3, embedding bug fixes, better performances and component upgrade (EMF...). Have a look to Eclipse Neon What's New and Tips and Tricks at
For instance, we can mention 2 nice ergonomic features available in Capella Project Explorer:

  • From a copied Eclipse project named "MyProject", new pasted project is named "MyProject1" instead of "Copy of MyProject"
  • Quick access to the location of your Eclipse project via its "Properties" dialog

Basic ergonomic enhancements for Linked Text of Opaque Expression (back-ported to Capella 1.1.2)

Linked Text editor is now editable. Users can use the key "Ctrl+Space" to add links to model elements


Unused Constraint are detected through a new Validation Rule I_36 (back-ported to Capella 1.1.2)

New validation rule (I_36) with related quickfix checks whether a Constraint isn't used in the model (constraining an element or used through Guard / Pre-Postcondition, context)

I 36.png

Ease the Constraint edition for Guards, Pre/Post condition, Exchange Context, Change Event, Time Event and Owned Specification (back-ported to Capella 1.1.2)

Constraint edition is facilitated, with Linked Text and Content Assist for:

  • Guards
  • Pre/Post condition on scenario and Capability/Realization
  • Exchange Context on Scenario
  • Expression on Change Event and Time Event
  • Owned Specification on Constraint


Provide a specific blue color for functions allocated to Actors (back-ported to Capella 1.1.2)

In Project Explorer, Semantic Browser and wizards, Functions directly allocated to Actors (i.e. Actor Functions) are now displayed in blue.


Project migration more explicit and better documented (back-ported to Capella 1.1.1)

To avoid migration mistakes, Capella migration documentation has been updated and only Project migration menu is available by default. Advanced migration menus (on model or diagram files) hare been masked by default. A new Migration category is available in Preferences: Capella > Commands Configurability > Commands


Optimize DCON_01 Pattern Conformance check and provide quickfix to clean unreferenced patterns (back-ported to Capella 1.1.1)

If there is no catalog at all or all catalogs are closed, the rule DCON_01 stops with the error message “No catalog found or all catalogs are closed”.

DCON 01.png

In case of pattern not being loaded, the rule DCON_01 proposes 2 quickfixes:

  • The first one is a soft delete in which only pattern instances are deleted, instantiated pattern elements are kept.
  • The second one is a hard delete in which both pattern instances and instantiated pattern elements are deleted.

DCON 01 Quickfixes.png

New validation rule DCON_03 to detect invalid pattern instances and provide quickfix to clean them (back-ported to Capella 1.1.1)

Rule DCON_03 can detect dangling Pattern Instances whose references are missing. A quickfix is then provided to clean invalid pattern instances. Note that DCON_03 must be launched from the Capella Project element (hidden by default) which can be shown by checking Capella > Project Explorer > Project preference.


New Validation Rule DCOM 21 – Unused Function Port Exchange Items (back-ported to Capella 1.0.5)

This new rule triggers a warning when a Function Port conveys an Exchange Item which is not allocated to any connected Functional Exchange. A quickfix allows to remove those exchange items from the allocating port.

DCOM 21.png

New Validation Rule DCOM 22 – Unsynchronized Function Port Exchange Items (back-ported to Capella 1.0.5)

This new rule generates a warning if i) outgoing Functional Exchanges from the same Function Port do not convey the same Exchange Items or ii) incoming Functional Exchanges to the same Function Port do not convey the same Exchange Items. The rule is by default disabled.

DCOM 22.png

New Validation Rule I 35 – Related Functional Exchanges must have identical names (back-ported to Capella 1.0.5)

This new rule generates a warning for Functional Exchanges connected to the same Function Port and do not have identical names. The rule is by default disabled.

I 35.png

New Validation Rule DWF_I 23 – Compare expected and actual Exchange Items on generated Interfaces (back-ported to Capella 1.0.5)

This rule compares the expected and the actual exchange items on Interfaces that have been generated by the “Generate Interfaces from allocated Functions” modelling accelerator and proposes several quickfixes.

  • In case of Exchange Item being present on the Interface but not on any Functional/Component Exchanges

I 23 Case1.png

  • In case of Exchange Item being present on Functional/Component Exchanges but not on any generated Interfaces

I 23 Case2.png

Propagate/Synchronize Exchange Items to Function Ports (back-ported to Capella 1.0.5)

The old accelerator “Propagate Exchange Items to Function Ports” as been renamed to “Synchronize Exchange Items on Function Ports”. The new accelerator no longer deletes Exchange Item allocated to Function Ports. It is available when one or more Functions or Functional Exchanges are selected.

Generate Interfaces from Allocated Functions (back-ported to Capella 1.0.5)

The modelling accelerator “Generate Interfaces from Allocated Functions” has been completely reimplemented with the following changes:

  • Internal Functional Exchanges are not considered when the accelerator is executed on a given component
  • Component Ports are no longer generated. Component Ports must now exist prior to accelerator execution, and at least one of the following must hold:

1. A Function Port is allocated to the Component Port
InterfaceGeneration Case1.png
2. A Functional Exchange is allocated on a Component Exchange that is connected to the Component Port
InterfaceGeneration Case2.png

  • The accelerator optionally propagates Exchange Items to Function Ports and creates a Component Exchange between each unconnected Component Port pair. These options are set in the Capella preferences under Capella->Transitions/Generation

Integration of new Acceleo Query Language (AQL) to navigate and query an EMF model

AQL is a language used to navigate and query an EMF model. It is advised to use it for diagram specification (odesign) for better performance, compared to legacy Acceleo 2 or Acceleo 3. A new "Interpreter" View is available to query your model using AQL language (see AQL documentation, link available in Capella Help Content) and supporting legacy Acceleo 2.

Diagram palette tool ergonomic: merge insert Function and insert Actor Function tools

In XDFB diagram, the "insert Actor Functions" tool was removed and its behavior was merged with the "insert Functions" tool.

New information added in Semantic Browser for Capability Realization elements (back-ported to Capella 1.1.2)

From a Capability Realization, involved Actors and Components can be navigated:

CapabilityRealization involvedActorsComponents.png

From either a Logical Actor or a Logical Component, involving Capability Realizations can be navigated:

LogicalActor CapabilityRealization.png

Do not allow to modify Physical Component Nature through Properties to avoid model inconsistency

By default, changing the Nature of a Physical Component after creation is disabled. This policy is controlled by a preference in the Capella/Model preference page.

Enhance Capella diff merge matching policies to manage complex use cases

Advanced matching policies have been added to Capella (e.g. based on name or structure, etc... instead of identifier). Additionally, a revamp of the GUI has been made in order to distinguish between simple predefined usages and advanced usages, and avoid exposing non-experts to the advanced features.
EnhancedDiffMerge 1.png
EnhancedDiffMerge 2.png
Each item in the GUI has an associated tooltip that provides some explanations
EnhancedDiffMerge 3.png
The Diff Merge editor has been enhanced, providing for instance the ability to reload ("Update ..." menu) a new comparison if models have changed.
EnhancedDiffMerge 4.png

Computed simplified links between parent components

The goal is to display computed exchanges that are defined between children components (deployment or breakdown).

On LAB and PAB diagrams, if a Component Exchange (CE) or a Physical Link (PL) has its target Component/Node hidden or removed from diagram, its target become the target parent and the edge is dashed.The target port is not displayed because it is not an actual port of the Component/Node.

Two new filters (disabled by default for new Diagrams created) are added in LAB and PAB to hide these "computed" exchanges :

  • Hide Computed Component Exchanges
  • Hide Computed Physical Links

Existing LAB and PAB diagrams coming from previous major releases are not impacted (i.e upper filters applied to hide these computed simplified links in order not to modify the current display).

Provide Migration in command line for Capella filesystem models

The command imports the model into the specified workspace and migrate the project inside. It is documented in Help Content > Capella Guide.
Example: <CapellaInstallationPath>/eclipse.exe -nosplash -application org.polarsys.capella.core.commandline.core -appid org.polarsys.capella.migration -import D:/Projects/ -data <workspacePath>

(Prototype) Ability to transfer model elements from one project/library to another referenced library

A first prototype is available in order to get feedback. New fixes will be delivered in the next Capella 1.2.1. This capability has to be used with caution: you have to check the resulted source/target model/library. A new View "Move Elements View" located in "Capella (Incubation)" category provides the capability to transfer model elements from a project/library to a referenced library.
It detects illegal backreferences and check Capella Semantic Validation based on Business Queries (same as Properties "Browse") in order to avoid model inconsistency.
ModelElementTransfer 1.png

Provide a read only capability on instantiate RPL

Capella provides a validation rule for RPL with Blackbox compliance. If it is enabled, live validation will occur on all RPL which have the "Enfore RPL Compliance on the Fly" flag checked in its properties. If this live validation detects a violating change, the change is rolled back and an error dialog will open, indicating which changes were not in line with the current compliancy setting of the RPL.

Straighten Edges Horizontally or Vertically enhancement

Four additional contextual menus are added under "Layout > Straighten" for selection of one or more edges.

  • "To Top" or "To bottom"

Straighten 1.png

  • "To left" or "To right"

Straighten 2.png
Some special cases when less straightening options are proposed:

  • "To bottom" is disable because over lapping of ports are not possible

Straighten 3.png

  • "To top" is disable because not possible to straighten the edge in void space

Straighten 4.png

Usability of Straighten layout of edges

The "Straighten To..." tool is now added directly in the toolbar of a diagram too, not only on right clicking (Layout/Straighten/...). It is now possible to select several exchanges (with or without ports) to align them and it applies the layout on all available edges, even if some cannot be modified. New capabilities to combine with other existing layouting features (Align, Distribute...):

  • "Straighten\With left side pinned" and "Straighten\With right side pinned" for horizontal layouting
  • "Straighten\With top side pinned" and "Straighten\With bottom side pinned" for vertical layouting

Straighten 5.png

Remove "Bend-points" works on Rectilinear edges

The "Remove Bend-points" option on rectilinear edge, like Oblique Style Routing, is now available.

Edge creation improvements

  • Edge creation with ports are now snap correctly.
  • When a new "Rectilinear" edge is created horizontal or vertical, it is correctly created horizontal or vertical, without useless rectilinear Bend-points.


Do not automatically scroll or provide a way to select element without scrolling

When diagram element is selected while it is partially displayed, there is no automatically scroll / focus on this element to display it completely.

Enhancement of the display of synchronization status on diagrams

  • Diagram visualization:

A new Diagram decorator appear in the bottom right of the opened diagram to indicate if the diagram is Synchronized or not (decorator appearing dynamically and not printed). It is disabled by default in Capella: a new Sirius/Sirius Diagram preference ("Show Synchronization status decorator on diagram") is available.

  • Perspective status bar Information:

An Eclipse status bar message indicates if the selected diagram is "Synchronized" or "Unsynchronized", at the end of the qualified patch of it.

It is possible to create an edge to the opposite side of a node

When creating an edge, it is now possible to force to select the opposite side of a node when the mouse is next to it

Ease the resize of fragments and inner Operands inside a Scenario

Inside a scenario, fragment resizing is now automatically done when:

   * User selects and resizes the Message execution from the bottom
   * User selects and resizes the bottom of the lower Operand side (inside this fragment)
   * User selects and resizes the top of the upper Operand side (inside this fragment).


Perform Sirius Actions on Multi-Selected Set of Model Elements

  • "Show Label" and "Hide Label work with a subset of diagram elements which can perform this feature (e.g. edge, edge label etc..).
  • Line Styles (Tree Routing Style, Oblique Routing Style and Rectilinear Routing Style) work with a subset of diagram elements with edges.

Export as image with better resolution

Provides auto-scaling (i.e. better resolution when exporting image from Sirius).
Due to performance issue, this functionality is not enabled by default in Capella 1.2.0. However, a new Sirius preference is available: Sirius/Sirius Diagram preference ("Auto-scale when exporting as image") to activate it. You can also enable auto-scaling by default in order to have smart exported documents, through an eclipse.ini customization.

Performance enhancement

  • The first launch of Capella is much quicker in Capella 1.2.0 thanks to the fix about plugin resolution algorithm in Eclipse Neon
  • Global Capella performance enhancement when refreshing diagrams: refresh time is divided by 2
  • Class Diagram performance enhancement when inserting/removing data or assigning a type to a property
  • New preferences not to expand trees in Transfer viewer Dialogs and to reduce label computation time


  • Avoid unnecessary refresh operations when executing tools & optimize refresh operations: more than 30% of gain on diagram modification
  • Session opening is faster (opening time almost dived by 2)
  • Existing logs MDEReport.html or CapellaCommandLineLog.html are now disabled by default to avoid non mandatory logs
  • Cross Referencer/eAdapter optimization to make massive modifications/navigation faster

Document enhancement

  • Provide quick access to capella help content from the Welcome page
  • Provide a way to extract and print all Capella subtopics and section hyperlinks. To extract all sub chapters, select each Eclipse Help book and click on button "Print Select Topic and its Subtopics"
  • Capella embedded documentation is enriched with:
    • Tips and Tricks
    • Capella developer Guides
    • Release Notes
    • Kitalpha Guides

New features

New diffmerge-based UI for display of transitions results and REC/RPL updates

Capella inner Transitions, addon subSystem Transitions and REC/RPL updates now use a diffmerge dialog to improve the merge readability. To simplify the merge, an "Apply" button has been added to "blindly" merge all differences from candidate model to result model. The transitions filters are now directly accessible from the diffmerge dialog
Image2016-12-14 22-51-13.png

Update Connections from RECs to RPLs

Update Connections from RECs to RPLs

Support of concurrent Regions in Modes and States diagrams

WN Region.JPG

Multiple Entry, DoActivity, Exit, Effects on State/Mode / Transitions

It is now possible to describe many Entry / do Activity / Exit on a State/Mode and many Effects on a StateTransition.

Enhance the reading of Capella diagram with gradient colors

The goal is to enhance the reading of Capella diagrams when they have some graphical elements with gradient colors starting from a blank background (Colors were too pale). For all kinds of Capella diagrams, it impacts only graphical elements with gradient colors:

  • " Function " (green),
  • " Operational Activity " (orange),
  • " Operational Entity " and " Actor " (grey),
  • " Component " and " Actor " (blue),
  • " Node " (yellow),
  • " Configuration item " (grey)

The blank background color which can lead to sometimes misunderstanding (for instance component types located in some blank background corner of gradient color component in PAB diagram) is replaced by a light related color (e.g. a light green for " Function "). But to keep a small gradient color (to ease the reading of graphical decomposition) and without modifying completely the original color contract, we have emphasized lightly the related dark color only for " Function ", " Node " and " Component ".

Enhance the reading of Capella scenario: labels and lifelines

To ease the reading of scenario and its labels (sequence message names ..), the color of lifelines will be changed from black to gray.

Diagram toolbar "Arrange Linked Border Nodes" renamed to be more explicit for users in "Arrange Connected Ports"

  • Diagram palette tool "Arrange Linked Border Nodes" was renamed to "Arrange Connected Ports", more explicit naming.

Note: The tool arranges ports having connected edges to shorten distances. Don't forget to "unpin" the layout of these ports.

Diff/Merge UI enhanced for better end-user experience

Filtering: The new category mechanism illustrated above allows filtering out, and/or focussing on, certain differences or model elements. It is intended to ease the understanding of differences of interest and speed up the merge process. Similarly to what has been done with the Capella Transitions and the REC/RPL mechanism, it can be customised according to business needs, although only in a programmatic way for the moment.

Local history: The Diff/Merge UI now integrates with the local history of files. By default, Capella keeps a local history of every file in the workspace, independently of any version control system. It is limited in size but this limit can be modified or removed via the preferences (Preferences, General, Workspace, Local History). Thanks to this mechanism, whenever a mistake is made it is possible to roll it back; now it is also possible to visualize and roll back changes individually through the Diff/Merge UI.

Version Control Systems: The Diff/Merge UI now has the ability to interact with VCS clients embedded into Capella. Initial integration with Git and SVN exist: they are only available as technical Eclipse features for the moment, to be made available as Capella add-ons later.

Image2016-11-30 13-54-30.png

LH IFE.png

Capella 1.1.0 support multiple screens

With Capella 1.1 based on Eclipse Mars, you can detach an editor outside Eclipse and work with it in other screen.

Image2016-10-11 19-34-32.png

Behavior inconsistency for Diagram toolbar actions "Make height and width same size" & "Apply the appearance"

  • The "Apply the appearance" action will consider the last selected element as base style, like "Make height and width same size". diagram element is chosen to be the reference

Ability to use mouse wheel click (middle click) to move in all directions (horizontally and vertically) of a diagram

  • Go through large diagrams and move in all directions (horizontally and vertically), using mouse wheel click "Middle click", like key binding "Space + Mouse left click".

Alignment tools (Snap to Shape) is now available on Ports

The feedback easing alignment to other elements when moving an element is now available on ports and collapsed ports.

Reset to default filters

When there are some filters enabled by default (Class Diagram, Interface Diagram, Architecture Blank..), a new menu allows to restore to the initial list of selected filters.

Zoom centered according to the mouse position

The zoom is done on the point behind the mouse to zoom directly the element targeted.

Clickable area shall not be scaled with zoom factor to make small elements better clickable by using high zoom factors

When the style of the node produces a visual size equals or greater than 20px or when End User uses a high factor zoom, the selection box around a "port" shall be resized too to ease link selection when ports are too close.

User-friendly layout mode – moving ports when containers are positioned very close to each other

Enhance the diagram feature "layout mode" The goal of this feature is to restrict the moving of ports strictly to the border of the owning component, when containers are positioned very close to each other.
Image2016-6-28 15-3-16.png

Labels of exchanges cannot be moved when clicking on the border (when the mouse icon changes to a cross)

The goal of this feature is to enable edge label motion after clicking on label and trying to move it when a cross appears.

Multi selection for graphical move of ports+exchanges

By selecting multiple edges with ports and pressing F3 key, you can move them simultaneously.
Move multiple edges with ports.png

Snap back labels on edge selection

Although there is already a button to snap back a label to it original position on label selection, a new button "Snap Back Label(s)" on edge selection allows to snap back all labels (source, middle, target) of this edge at the same time.

Allow editing of note & text

Now you need only a slow double click to edit a note or a text, not three. It is consistent with all others graphical elements.

Format tools should be available on label selection

For edges format tools in Diagram toolbar (tabbar) are not available on label selection too, not only on edge selection.

Known limitation: when the edge more than one label (for instance labels of Class association, association and roles), the label format will be applied on all associated labels.

Add new Layout commands to set edges with connected ports vertical or horizontal

The goal of this feature is to assist user to set edge selection vertical or horizontal in order to help exchange layout. If the edge is connected to "ports", the "port" is moved too.

  • Layout/Straighten/To top
  • Layout/Straighten/To bottom
  • Layout/Straighten/To left
  • Layout/Straighten/To right

Image2016-10-3 15-32-26.png

Extend the copy/paste layout in copy format, paste format/layout/style

Now when you copy the format of a graphical element, you can paste the layout, the style, or both (format). Note: When you quickly copy (Ctrl+C) a graphical element through a diagram and paste (Ctrl+V) it, style and layout are both pasted.

Now, Capella Copy/Paste from diagram copying model elements and trying to paste them into target diagram uses these Sirius enhancements. By default, default diagram Copy (Ctrl+C) and Paste (Ctrl+V) paste model and diagram element format. But now, other sub menus are available to paste only layout or style.


Diagram export and gradients

Now, diagrams using color gradients are correctly exported as images when you select an available Export As Image format.

Preference to show computed link between edges and its labels on edge selection or label selection

It is a new preference added in Sirius > Sirius Diagram > Connections.

When you select an edge or a label, graphical link appears between them.

More friendly shortcut for "reset origin": Ctrl+HOME

Initial shortcut (Ctrl+&) for "reset origin" diagram feature was not an Eclipse valid shortcut (displayed "Ctrl+"). So it has been replaced by a more friendly one Ctrl+HOME.

Global Capella performance enhancement when refreshing diagrams

When diagram automatic refresh is enabled (by default on filesystem models), refresh time is divided by 2.

Capella 1.0.0


Capella 1.0.0 is based on:

  • Eclipse 3.8.2
  • Kitalpha 1.0
  • Sirius 3.1.2

Projects migration

Migrate your Capella projects created with Capella 0.8.x to Capella 1.0.0.

Embedded documentation

Capella 1.0.0 documentation is available inside the workbench (Help menu).


Suffix management and renaming propagation

  • Suffix on RPL is now kept on each RPL (M2)
  • From Capella 0.8.x to 1.0.0, migration process deduces existing RPL suffixes, if possible
  • Propagation of name on update is better handled when RPL suffix exists

02-Suffix Management.png

Compliancy validation rule for RPL compared to its REC & vice versa

Validation rule to determine if an RPL needs to be updated

  • From a REC, list all RPL to be updated + QuickFix
  • From a RPL, check if it requires an update + QuickFix


Prevent mixing Mode/State

Mix Mode/State in hierarchies is not recommended

  • Validation rule (DWF_SM_06) to detect Mode/State mixes + Quickfixes
  • Mix Mode/State is prevented by default, see related preference

04-Prevent Mixing.png

Activity Explorer (Overview)

Overview becomes "Activity Explorer" Open Source component (Amalgam)

  • It can be customized via preferences to hide some Pages/Sections/activities
  • Customizable by code

05-Activity Explorer.png

Libraries cycle check

A new configuration option to prevent cycle creation between libraries (Deactivated by default) & live management with acceptable performances

  • New validation rule to check cycles and analysis wizard

06-Libraries Cycle.png

Ability to rename elements in Node list diagram elements

Properties, Exchange Items and other elements can be renamed easily through diagrams (F2)

07-Rename Elements.png

Color parent actor function

Parent functions where all leafs are allocated to actors are now displayed with blue color

08-Code Parent.png

Progress Statuses of diagrams

Progress statuses of diagrams are now displayed in the Monitoring Overview

09-Progress Statuses.png

Accelerator button for String Association and Type

Properties accelerator button for String Association/Type

09-Accelerator 1.png

10-Accelerator 2.png

Display value of property value

Value of "Property Value" is now displayed in Project Explorer

11-Display Value.png

Display units on a property typed & Property information in Explorer

More detailed displaying (Unit...) of properties in project explorer and diagrams

12-Display Units.png

Context of IS Scenario refinement and EI Communication Links

  • At the SA level: communication between Actor and System via Exchange Item
  • At the LA level: Communication link between Logical System and Exchange Item and Communication link delegated to sub-components

13-Context IS.png

Refinement of Interface Scenario does not work with Communication Links

Now, IS refinement reflects the consumption of Exchange Item via Communication Link, and not only EI referenced by use/implement/provided/required Interface

14-Refinement IS.png

Cannot distinguish seq message with Refinement ambiguity

From the Refinement ambiguity dialog, it is now possible to navigate to the ambiguous scenario/sequence message/component and analyze impacts


Logical Component Decomposition Wizard improvements

  • Improvement on displaying Communication Links (symbol and name)
  • Provided/Required interfaces can now be delegated to sub components

16-Logical Component.png

Consolidate model validation on Component and Data

Validation rules:

  • DWF_D_49 : Maximum Cardinality Of Key Parts Equals 1

In a class, when a property or an association role is part of key, value of maximum cardinality must be equal to one.

  • DWF_D_50 : Maximum Cardinality Value Is Defined And Evals To Natural

In class property, association role and exchange item element, maximum cardinality value is defined and, unless abstract, evals to a value in [1, *[.

  • DWF_D_51 : Minimum Cardinality Value Is Defined And Evals To Natural Or Zero

In class property, association role and exchange item element minimum cardinality value is defined and, unless abstract, evals to a natural or zero (i.e. integer belonging to [0, *[).

  • DWF_D_52 : Type Of Default And Null Value For Property

For a property, type of the default (resp. null) value shall be Undefined (implicit typing) or the property’s datatype or a super type of the property’s datatype.

  • DWF_D_53 : Property Or Role Overriding Is Not Allowed

A property/role in a class shall not have the same name as a property/role of a super-class.

  • DWF_D_54 : Property Or Role Respects Covariance

If class K inherits class C, if property or association role is owned by C with type/class A and redefined in K with type/class B, then B inherits (or is equal to) A.

Resizing enhancement

Resizing graphical node no longer move edges if not necessary


Arrange Linked Bordered nodes (edge/ports)

Have "arrange linked bordered nodes" action layout correctly edge/ports with rectilinear router

18-Arrange Linked.png

On tool creation specify the element selected (edition/D&D)

On tool creating edge+ports, only edge is selected and can now be directly renamed (F2) after creation & port D&D better handled

19-Tool Creation.png

On tool creating breakdown, created element can be renamed (F2)

19-Tool Creation 2.png

Label position on edge movement

After edge layout modification, label position is kept nearer to it

20-Label Position.png

New edge+ports moving feature (Shortcut "F3")

With shortcut "F3" when moving an edge with its ports (multiple selection implemented later), it is possible to move edge and its ports around containers

21-Edge Moving.png

Fix vertical edge creation

When feedback on edge creation is vertical, created edge could be oblique in 0.8.x

22-Fix Vertical.png

Alignment to inner elements (Shortcut "F4")

With shortcut "F4" when moving an element, it is now possible to align with inner elements and not only to external ones


Hidden border

Ability to hide border on a container element, especially useful when an image is displayed

24-Hidden Border.png

New border line style for nodes and new font style for labels

Ability to update border line style (dot, dash, dash_dot) and new font style (underline, strikethrough)

25-New Border.png

Anchor on inner element border

Now the edges are linked closely to the images. You only need to use images with a transparent background (SVG images)


XHTML Model Output

Data Values, Complex Values & Contraints/ Opaque Expression are exported



  • Integration of partial generation
  • Improvement of clickable zones on generated diagram
  • Improve algorithm to calculate clickable zones on generated diagram for big models

Transition System to SubSystem

  • Transition of Functional Chain with multiple crossing:

Created functional chains are no longer invalid: A fake Functional Exchange is created between reentrant functions to describe the external path

28-TSSS FC.png

  • Transition of unnecessary elements:

During a multiphase transition, Functional exchanges inside an actor (those without direct contact with the sub-system) are not created in the target model

29-TSSS Unnecessary Elts.png
