TRAIL: The SysML-v2-Pilot-Implementation GitHub samples in Cameo by Webel

examples

This slide trail is NOT a SysMLv2 language tutorial! Slides here are offered as is (some without further explanations) in the hope they may be of interest. To learn SysMLv2 attend the Webel SysMLv2 Seminar Workshop group course. Individuals may instead purchase access to the Webel SysMLv2 Online self-study eLearning course with self-test Quizzes to learn at their own pace.

Modelling and style

Cameo SysMLv2 Plugin: LIMITATION: Does not have a compartment for basic refs (no kind) so one has to use symbols, which takes up some modelling real estate - even when there's no need to show their structured contents or relationships from them!

TIP: SysMLv2: Cameo: PREFER use explicit attribute or item kind when redefining (even if a bit tedious in code). Otherwise you can't list them compactly in compartments as Cameo does not have a compartment for basic refs (showing Symbols takes up space)!

Some minor geometry issues (which don't detract from the value of the SysMLv2 sample itself):

ISSUE: SysMLv2 GitHub examples: Multiple cases: ShapeItem Cylinder does not (currently) have a 'radius', it inherits a 'semiMinorAxis' and 'semiMajorAxis' which are not redefined. (It DOES have a 'height').

The rotation of the leftFrontWheel should be +90 degrees not -90

And a more substantial issue:

The wcf wheel coordinate frame is referenced in the constraints for the lug bolts but is never defined nor referenced in the parent vehicle when the wheels are used.

[MODELLING, TIP, TOOL]{RECOMMENDED} Webel Best Practice: SysMLv2: Cameo: TIP: Show EITHER a specialization relationship from a symbol OR show the specialization in the symbol header using Display Styles -> Show Specialization. Prefer NOT show both modes in one View.
