The best SysML v2 Cheat Sheets!

What is the best way to model a part in SysML v2? Or how do I migrate my model from v1? What was that again with references in the text notation: :>, ::> or :>>? (Hint: it's ::>, but all three exist!) To provide quick answers to such questions, there are cheat sheets, i.e. short documents that provide quick answers.

Update 09.12.2025: Now the cheat sheet (4 pages) of SodiusWillert published. The focus is on the graphical notation and focuses on help with the application. More info

What are cheat sheets?

This is really about cheat sheets, short references that concisely summarize important information about modeling. For me, short and concise ideally means a single page, but some are a few pages long.

Of course, there is now a lot more material on SysML v2: books, slide decks, good videos, etc.. Some of them I have listed below (without any claim to completeness).

Cheat sheets have a long tradition in modeling languages. OOSE already had cheat sheets for UML and SysML for many years. Later, some tool manufacturers brought out their own cheat sheets.

Chat sheets are now not only available as PDFs or on cardboard, but also as posters, T-shirts or coffee mugs.

Challenge: Where are the tool manufacturers?

It would be expected that the manufacturers of SysML v2 tools would eagerly use this time to promote their own tools with guides, quick references and cheat sheets. But I have found surprisingly little. The best exception is the Summary of the text notation of Sensmetry.

Perhaps I have overlooked some. So here are the Request to readers and tool manufacturersIf you know of any good short references, let me know and I'll include them here.

Textual Notation Basics (Sensmetry)

I am a big fan of 1-page. Sensmetry, the company behind SysIDE, has created one for textual notation: As a separate webpage and also as a PDF:

SysML v1 -> v2 Migration Guide (US Department of Defense)

If you are wondering who is using SysML v1 and is keen on v2, this 2-page guide might provide a hint: This public domain guide has initially been created by the research arm of the US military, with Frank Salvatore being the actual author. A big thanks to Frank.

The guide was published at Digital Engineering: Body of Knowledge (DEBoK) a resource that I did not have on my radar screen yet. They have some great content, so I encourage you to explore the library.

OOSE & Dassault Cheat Sheet

A few weeks after this article was published, OOSE and Dassault were also ready to publish their one-pager. The focus here is on mapping between textual and graphical notation.

This cheat sheet has led to a heated debate between Sensmetry and Dassault led.

Cheat Sheet from SodiusWillert

SodiusWillert's sheet goes in a completely different direction: apart from a brief explanation, this 4-page PDF focuses on the graphical notation, supplemented with notes on how to use it in practice. This makes it complementary to the other cheat sheets I have presented here.

Please note that I have actively worked on this cheat sheet myself.

Guide to selecting the right model element

Not a PDF one-pager, but still extremely useful. On MBSE4U has Tim Weilkiens the guide Which SysML v2 Element to Choose? created. Extremely useful to avoid modeling yourself into a dead end.

There are a number of other articles on SysML v2 at MBSE4U, it's worth browsing.

Incomplete list of additional resources (no cheat sheets)

There are now a number of extremely good resources. While writing this article, I thought several times: "This source should not be lost". So here is a short list without any claim to completeness:

• Official specs: The official specs can be a little intimidating because of their length, but they are really well written. And more importantly, they contain lots of examples and it's quite easy to find your way around. Also, the OMG a lot more resourcessuch as videos or blog articles.
• MBSE for Dummies, Now with SysML v2: Siemens has long had the eBook MBSE for Dummies free of charge (with registration) offered. The 2nd edition of the book is now available, which also deals with SysML v2. One Review of the book was written by Paulin from Molo Molo Tech. But before you download the book, be aware: The book is not about modeling SysML v2. The book simply explains how SysML (and now v2) fits into the context of MBSE.
• Introduction to the SysML v2 Language Textual Notation: This PDF is 200 pages long and therefore certainly not a cheat sheet. But it is currently one of the best tutorials for learning textual notation.
• SysML2 state structure modeling: A Tutorial by Gerd Wagnerwho is also a Online book on KerML and SysML v2 has written.
• SE trends: And of course on this website about SysML v2 both by me and by guest authors.

Conclusion

This is an article that will actually be out of date by the time it is published, but that doesn't matter. I also intend to keep the list up to date. So if you come across a good SysML v2 reference: Please share it with me and I will include it here.
