General Board / Re: Not being able to type a FlowProperty with a Signal

« on: August 21, 2025, 08:55:34 am »

Just FYI,

With my free SysML add-in, we can create a FlowProperty with a Signal by dragging a Signal in the Browser onto an InterfaceBlock on a diagram. We do not need to have two (or more) steps to define an InterfaceBlock for a Signal.

Automation Interface, Add-Ins and Tools / Re: Enterprise Architect and AI

« on: August 18, 2025, 03:38:45 pm »

Hi Shimon,

Thank you for your reply. I am glad to hear that it works well with the latest installer.

As you guessed, currently some limited types and the profile-based types (such as ArchiMate) are supported. Please read the description of the tool to know which types are supported. This is because currently I think it is not easy for the LLMs to specify the correct Enterprise Architect element types. (For example, 'UseCase' is okay but 'Use Case' is NG).

About the Sequence diagrams, currently the MCP server supports exporting information from Sequence diagrams, to be able to generate source codes etc. from the Sequece diagrams. The server exports information about fragments too, so now I think it is enough to generate source codes from the diagrams.
Unfortunately, currently generating the Sequence diagrams are not supported, this is very difficult.

I have checked that the MCP server and Claude/ChatGPT on VSCode can generate source codes from the Sequence, StateMachine and Activity diagrams.

p.s.
Please send me the error information directly. I am the only one interested in the details.

Bugs and Issues / Re: Is there any chance to get baselining and comparison to work after somany years?

« on: August 14, 2025, 08:24:38 am »

The 'Visibility' in the Properties window of Enterprise Architect is stored in the t_object.Scope column internally, so this is not a bug.

The problem is that EA shows the internal column name in the Comparison view. It should be shown as 'Visibility,' the same as in the user interface.

Hi Shimon,

I have changed the way to find the Enterprise Architect installed path in the x86 installer and uploaded it as version 1.9.4.1.
Please check if it works fine.

Hi Shimon,

Thank you for your comment! I'm glad to hear that.

As I mentioned in my email direct to you, these installers seem to be fine. The file size does not mean that the MCP_EA_x86.msi is not an x86 installer.
If you try running the MCP_EA_x64.msi on a 32-bit Windows system, it will not work. However, the MCP_EA_x86.msi works well on 32-bit Windows.
(I have double-checked with the current files.)

Perhaps the problem lies in the way the installer finds the installed directory. The installer tries to find the EA installation directory. Perhaps your machine has information about the 64-bit version of Enterprise Architect. If there is information about the 64-bit version of Enterprise Architect, even if it has already been uninstalled, the installer tries to install the directory.

I will try to change the way the installer finds the installed directory.

Bugs and Issues / Re: Document generation broken in v16.1

« on: July 30, 2025, 09:10:54 am »

I cannot reproduce the issue on my machines, but changing the printer might produce different results.

From the Sparx logo button on the far left of the ribbon, select the Print Setup menu, change the printer, and then try generating again.

Using my free MCP server add-in, we can connect Enterprise Architect and AI.

Check the second video in the following page, I recorded creating a model from AI generation.
https://www.sparxsystems.jp/en/MCP/
(It might be better to mute to avoid my broken English - without voice we can understand what happened.)

The book 'AI Assisted MBSE with SysML' explains how to use AI for modeling.

General Board / Re: Publish to Standard HTML

« on: June 20, 2025, 02:06:35 pm »

Hello all,

Because of the JavaScript security limitation of the web browsers, now the old style HTML documents do not work as expected on the almost all browsers. So I think there is no way to use the old style HTML document generation.

If we want to change the width, add a new HTML template and then delete the 'max-width: 1400px;' line at line 643 in the 'CSS - Main' template.

General Board / Re: MCP (Model Context Protocol) server for Enterprise Architect has been released

« on: June 16, 2025, 04:48:08 pm »

Hello Williami,

Thank you for your comment. After my first post, I have updated my add-in several times to add more tools (features), fix bugs, and offer the installer for 32-bit version of Enterprise Architect.

Now I think the add-in offers enough features for exploring your model.
Please tell me if you have any idea, quetions and/or bugs.

Suggestions and Requests / Re: Improve/implement C language support

« on: June 10, 2025, 08:31:16 am »

Even if you use the Unified or Ultimate edition, you need to enable the 'Object Oriented Support' model option to generate C source codes from the behavioural diagrams such as the Activity diagrams, the Statemachine diagrams.

General Board / Re: MCP (Model Context Protocol) server for Enterprise Architect has been released

« on: May 30, 2025, 08:24:29 am »

I do not know it because I have not let any LLM understand the API and/or the table structure. I cannot imagine why we need it or in what situation.

General Board / MCP (Model Context Protocol) server for Enterprise Architect has been released

« on: May 29, 2025, 02:26:13 pm »

I have released the MCP (Model Context Protocol) server for Enterprise Architect.
You can connect MCP clients like Claude application and Enterprise Architect and ask to LLM about your model.

For detail and download the installer, please visit our page:
https://www.sparxsystems.jp/en/MCP/
(It is free to use. Not a paid product.)

I created a free SysML add-in that enhances modeling with SysML on Enterprise Architect.
I introduced this add-in at the Sparx Systems Global Summit 2025.

You can find more details and download the installer at the following URL:

Automation Interface, Add-Ins and Tools / Re: How to use ImportInternalDocumentArtifact()?

« on: May 26, 2025, 10:24:39 am »

@George:

I have maintained the help pages of the sparxsystems.jp. I have checked and added the missing methods/attributes so some of them might not be written in the English help.

Anyway, the Automation Interface is the same among all languages of Enterprise Architect, so you can use the method on the original Enterprise Architect.
