Diagram does not match the step-by-step instructions in the tutorial

[FrankBX2023]

In the Batmobile example from the SysML v2 beginner tutorial (based on the “Don’t Panic” book), the part wheels[4] : Wheel is supposed to be a part of Vehicle, as described in section 2.2 of the guide.

**

_> 2.2. Setting Multiplicity

Select the Vehicle part definition and click on the Structure → New Part tool in the Contextual Toolbar to create a new part usage

Rename the part usage to wheels._

**

However, in the provided diagram (e.g. in SysON or related sample content), wheels[4] is directly contained in Batmobile.

Hello,

Our Batmobile template is based on https://github.com/MBSE4U/dont-panic-batmobile/blob/main/DontPanic-SysMLv2-Batmobile.sysml.
In this example, wheels[4] is directly contained in Batmobile.

About the Don't Panic book, I have the version 1.0 here and there is no 2.2 chapter. In my version, the chapter 2 is "History of SysML".
May be the book has been updated since I have it.

Regards,

Hi Axel, could you check your tutorial (Step 2.2) and compare the steps with the picture https://doc.mbse-syson.org/syson/v2025.6.0/user-manual/hands-on/tutorials/batmobile.html - it doesn't fit

It is possible that this screenshot is outdated. I will update it, thank you.

The Screenshot is right (based on the no panic book), but the steps in the tutorial (to get this picture) are wrong

Ok thank you
