MD: Automated Model Variant Generation?

Does anyone know of a way to automatically generate MagicDraw model variants in a server project? My use case is that I am managing a number of variants in my 150% model. The process to generate variant models and commit each to a branch is manual and time consuming through the MD client. I would like to be able to generate the variant models automatically though something like the TWC API, a batch mode script, or even a macro.

Reqtify - Add high-level Requirements - Cameo and TWC

Hello, I have checked the new version Reqtify 2026x Gold and found that the 'Add high-level Requirements' feature is still not available for Cameo projects stored in Magic Collaboration Studio (aka TWC). It is only available for locally stored projects. The 'Add high-level Requirements' feature is necessary to efficiently implement traceability between requirements and models (in TWC). Could you please share your advice on this? Many thanks, Francesco Matraxia

Scripting in specification wraps objects into List

I have created a constraint and would like to define its specification as a groovy script -- this constraint will be stereotyped with <>, but this is irrelevant. I've had this issue with scripts in custom columns and other places, so it being a constraint is also irrelevant. When calling on an object's method, Cameo wraps an empty argument into an empty list. I've also seen a single element wrapped into a list, e.g., element is passed as [element]. In this particular case, my

Automating IBD creation

Good evening (or morning for whoever !) I'm struggling to initialize IBD for a bunch of already defined blocks containing partProperties, proxyPorts and connectors. I can't find a way to properly create view for connectors, probably because I didn't find a way to create ConnectorEndView objects for related ConnectorEnd objects. Does anybody have an idea ? Here is an extract of my groovy script: SessionManager.getInstance().createSession(project, "Create IBD for " + block.getName()); Diagram

Build Hierarchy Scope Query with Smart Package Input?

Is there a way to use a Smart Package as the input to generic table that uses the Build Hierarchy option as part of a Scope Query? I've successfully used the Build Hierarchy option before, but it seems that it requires a user to manually add the top-level elements to the scope of the generic table. I'd like to expand this capability to have the top-level elements specified by a Smart Package so I can use the Smart Packages query option to find the top-level elements for the table. However,

Can Cameo Generate a Report of Classes based on Public/Private/Protected status?

We're using Cameo's Code Engineering tool to generate class diagrams based off of pre-existing Java code. One of the things we have been tasked with is to identify code that is dead or orphaned, and in order to try to figure that out, I wanted to generate a list of the classes in the model based on whether they were set to private or protected. However, when I look at the classes that we have in our model in Cameo's Specification window, the visibility for all of them are set to public. I've

How to know the simulation of an instance table is done

Currently, I am using Jython to develop custom functions in CAMEO. After the simulation is done, the instance table (including results) should be automatically exported to a CSV file. However, the problem is that it is not waiting for the simulation to finish; the table is already exported, so there are no results in the CSV file. Could someone help me solve this issue? The methods I have tried are as follows, but they did not work properly: Using a time delay. However, the script always runs

Guidance on Number of Commits / Project Versions

Is there guidance on how many Commits / Project Versions there should be on TWC before needing to save off a copy of the project and archive it, and start over with a fresh project history? The team is saying our commits are getting high and the project would run faster if we started fresh. I would rather not have to keep saving off baselines of the TWC server project every time our commits get "high". Does the number of commits on a project really affect performance that much anyway?

Is there an easy way to cross-link class diagrams generated using the Code Engineering tools in Cameo?

Hi. We're currently working on a project to use the Code Engineering-Reverse tools in Cameo to ingest code and generate class diagrams from that code. The code base we're working from is very complex, and has many multiple sub-systems/sub-directories. We've generated the class diagrams from these sub-systems, but is there an automated way to be able to find and create the connections between the sub systems/sub folders?

A SysML model is created in Magic Cyber Systems Engineer. A Groovy automation script is used to generate a connector in an Internal Block Diagram (IBD) populated with the required parts. The script explicitly specifies: - The connector name - The source part - The target part However, upon execution the connector is not created in the IBD, even though the script runs without errors. Does anyone know how to resolve this? Please find the model and the groovy script.

Distinguishing Diagrams in the Diagrams Tab by Model

Hello - Is there a way to have the diagrams tab separate out diagrams from different models in a project? In our classes, a lot of times we have a "sandbox" package or model element we illustrate concepts with and it would be nice to not have those diagrams intermixed with the example model we are building. Thanks.

How do I configure an Output Pin to emit a constant enumeration literal in CATIA Magic SysML?

Hi all, I’m working in CATIA Magic (SysML Activity Diagram) and I need an action to always emit a fixed enumeration literal. Setup: I have a ValueType with enumeration literals (e.g., ON, OFF, FAULT). In my activity diagram, I have two actions. Each one should output a constant:Action A → ON Action B → OFF The output is meant to flow into an activity output parameter node typed by that same ValueType. What I’ve tried: Added a Value Pin with the literal attached. That works for typing, but the

Join Spec Example

I'm curious if anyone has used the join spec field in join nodes to change the simulation behavior of a join node. It seems like it would be useful to add some additional logic to the join node. At the moment, if "Is Combine Duplicate" the join node is supposed to package all incoming objects in an array and send them through. But what if i want only one (or a few objects) to come through. Currently I'm using another action to complete that behavior, but it would be great if I could build that

Limiting the blocks that you can type a part property to

Does anyone know of a way to limit the blocks that you can type a specific part property to? How it would work is that when you select the type field of the part property it only gives you certain blocks in your model rather than all available blocks in the model.

Dymola for presentations

Sometimes I want to make a live demo of Dymola or include some screen shots in a presentation. The problem is that Dymola is designed for the normal viewing distance of the user. So whatever you show will be nearly invisible on row fifteen. Here are some tips to increase legibility.

Question about Architecture Frameworks and SysMLv2

Hi all, I'm in the process of updating my lecture materials for the course where I teach students about the different architecture frameworks (i.e. UAF, DoDAF, etc). What are the current opinions about the future of these frameworks with SysML v2? I'm searching various internet sources for any information about this. @Aurelijus MORKEVIČIUS and @Gintarė KRIŠČIŪNIENĖ : I read your INCOSE paper about UAF and SysML v2. Have you received positive feedback about that paper and pending UAF updates?

How can I save or reuse a custom Requirement Table layout in CATIA Magic?

Hi all, I’ve configured an L1 Requirement Table in CATIA Magic with all of the attributes and columns I need (custom stereotypes, Boolean/string attributes, enumerations, etc.). Setting this up was pretty time-consuming, so I’d like to avoid repeating the process every time I need a new Requirement Table. Is there a way to: Save the column/attribute configuration of a Requirement Table as a reusable template or “mask”? Apply that saved layout to other Requirement Tables in the same project (or

Custom elements creation with autonumbering

Hi, I have an element customization that uses autonumbering. I want to create an instance of that element that also sets the numbering using a groovy script. The customization works fine if I create the element manually from the containment tree but I haven't found a way to do it cleanly in a groovy script. I am using the elementsFactory to create the element in the script as shown below: newElement = elementsFactory.createClassInstance()

Alternative to deprecated `EsiBranchInfo` and `getLocalId()` in Cameo 2024x

Alternative to deprecated `EsiBranchInfo` for retrieving branch name in Cameo 2024x In Cameo 2024x we noticed that EsiBranchInfo appears to be deprecated. We were previously using it to retrieve the current active branch name of a Teamwork Cloud project checked out in Cameo. Is there a new or recommended API/class we should be using instead to get the branch name? Ideally we are looking for the direct replacement that works in 2024x. Alternative to deprecated `getLocalId()`: We used to use

How to get DataHub to use semicolon as delimiter for CSV files?

I would like to use the DataHub plugin of CATIA Magic Cyber Systems Engineer (2024) with a csv file, but I can't find where to set the delimiter character. CSV files with a delimiter of a coma are almost useless for requirements since requirements will contain comas as a part of the English sentence structure. When making csv files with text content it is very common, almost standard to allow the delimiter character to be set to a semicolon, which is easy to avoid in English text. Can someone

Providing a custom ImageLibrary

Hello, I would like to provide a custom ImageLibrary to CATIA-MagicSoS end-users.
