Portion Marking representation to improve diagram readability

Using the data markings and classification plugin, data markings applied to blocks/packages are currently displayed as prefixes or suffixes to the block name through the "portionMarking" representation attribute. When multiple markings are applied, the block label becomes crowded and difficult to read on diagrams and containment browser. Legends can also not be used in case of multiple markings applied that need to be distinctly identifiable. Is there a better way to represent multiple data

Expand/Collapse Relation Map Diagram from Web Publisher 2.0

Hello everyone, I am wondering if anybody heard of possibility to expand/collapse Relation Map Diagram generated by Web Publisher 2.0.

Sending a signal in parallel over multiple connectors

I am having an issue modeling where I try sending a signal using a send signal action over a port that has multiple connectors attached to it. When the send signal action activates, the signal is sent over each connector, but it is in series and not in parallel. I need it to where the signal is sent over every connector on that port at the same time and not one at a time. Anyone know what to do?

Format for creating new element in v2 API?

Hello folks - I have successfully used the v2 API against TWC to download model elements and to change them via the commits POST endpoint. However, when I consult the v2 API cookbook on creating new model elements, it tells me to delete any references to model identity (DataIdentity, @id). All well and good since there is no ID on the server yet. However, when I do this I get jackson XML errors saying that a key cannot be found in my JSON. When I keep the keys but leave the fields blank, I get

Hello Everyone, I try to import requirement specifications form excel file to enovia environment with reqtify tool. I have some problem. I able to capture requirements and attributes while defining the rows but I didnt define the chapters. I was arrange the chapters on the enovia manually. when I import the excel files for updating the documents reqtify moves the requirements. I dont want to change the hierarchal structure on the enovia while update document while import. I think may possible

Connecting Functional with Structural Architecture with SysML v2

I'm learning SysML v2 with CATIA Magic Systems and am trying to create a model with functional and structural elements and a connection between those. I'm trying two approaches (1. actions own actions - 2. parts own actions) and with both approaches I would like to see a diagram of the system function showing how the subsystem functions are connected and allocated to the subsystem parts. It's working well with approach 1. - with approach 2. it does not show the swimlanes.. What am I doing wrong?

Cameo web publisher report wizard does not generate diagrams

Hi, I would like to generate a HTML report for non-system architects review. I am using the VCCS (MG Bok V2 sample). I would like to export all diagrams, that is, SysML and Cameo tool diagrams. I did use the Cameo menu: Tools -> Report Wizard I did try two templates: 1 - Default template -> Web publisher (simple HTML) 2 - Web publisher 2.0. -- For the first (Web publisher (simple HTML)) For the first HTML I did use the default Cameo default options and all the model elements as below: I did

SysML V2 MagicDraw and Simulink communication on separate hosts

We are considering building a co-simulation environment using MagicDraw and Simulink. In this setup, MagicDraw would be deployed on one host to perform system-level logical simulation, while Simulink would be deployed on another host to conduct flight control simulation. The two hosts would communicate with each other via an Ethernet (RJ45) connection using UDP. In SysML v1, we previously used Opaque Actions to invoke Python code and transmit numerical data via UDP communication. However, in

Q&A Following the OMG & CATIA Webinar -Taming the Beast: Best Practices for Extending SysMLv2 (Jan 22, 2026)

Dear Community Members! On January 22, 2026 we had the webinar organized together with OMG. @Aurelijus MORKEVIČIUS and @Gintarė KRIŠČIŪNIENĖ presented the topic Taming the Beast: Best Practices for Extending SysMLv2. The replay is here. We shared hard-won lessons from developing SysML v2 libraries for the Unified Architecture Framework (UAF)v2 — a project that pushed the SysMLv2 extension mechanism to its limits. Our distinguished speakers worked closely with SysMLv2 leadership to navigate

SSP - System Structure and Parameterization

The System Structure and Parametrization (SSP) standard defines a common format to describe how multiple simulation models are connected and configured. It focuses on system architecture, parameter settings, and signal connections, rather than model behavior itself. SSP enables consistent setup, reuse, and exchange of complex multi-model simulation systems across different tools. 🌐 SSP Standard: https://ssp-standard.org/ Find some general information about SSP in the below wiki page.

eFMI - Functional Mock-Up Interface for Embedded Systems

The embedded Functional Mock-up Interface (eFMI) extends the FMI standard to support embedded control software development. It enables the exchange of models optimized for code generation and deployment on embedded targets. eFMI provides a standardized way to generate efficient, verifiable C code from simulation models, ensuring consistency between simulation and real-time execution on hardware. 🌐 eFMI Standard: https://www.efmi-standard.org/ Find some general information about eFMI in the

Flow payload validation in SysML V2 in MagicDraw 26HF1

I defined streaming flow def FuelFlow with the constraint that the payload is of type "Fuel". I defined a flow usage with FuelFlow type but with payload "water". However, it doesn't seem to have any conflict or validation error popping out? I am wondering whether I did it wrong and how I can activate the validation to force the type check. Also, do we still have the structure view and behavior view flow synchronization?

Import SysML v2 Folder into Cameo

Hello all, Can I add a local folder with subfolders containing .sysml-files into Cameo Community Edition? To be more precise I would like to open this repository: Thanks!

Question about Include Use Case Swimlanes

I have a question regarding include use cases. According to the SysML v2 Specification, an include use case is both a kind of use case and a kind of perform action. I attempted to construct a model in which a part contains two part features, namely Part1 and Part2, and the part also contains an include use case. Since an include use case is defined as a perform action, when I select the part and choose “Show Swim Lane”, I expected to see Part1 and Part2 represented as swim lanes. However, the

MagicGrid traceability subsystem at solution domain

Hi, I have reading and using the MagicGrid BoK V2, I do have questions about satisfy traceability between textual requirements and model elements. Below a capture from 3 different diagram from the MagicGrid BoK V2: Satisfy traceability matrix between subsystem textual requirements and model elements on the left. Subsystem textual requirements - top right. Subsystem activity diagram, bottom -right. The BoK example shows the satisfy traceability AND for behaviour should be done between call

SysML V2 Plugin:Tabular View Read-Only?

I am trying to edit the part usage name in the general table view. But it seems that the cell is read-only. I am curious how I can make it editable?

SysML V2 Flow & Connection/Interface

My question is whether there is any method that I can have connection and flow both in Symbolic view between two ports. In Symbolic view, I build a connection between two ports and then in textual view add flow between two ports. However, there are two lines between ports, one is flow the other is connection. I am wondering whether I can build flow on the connection only in Symbolic view without two lines between two ports.
