Screencast: MagicDraw SysML/Cameo analysis: Possible "gotchas" when extending the SysML Block stereotype

Keywords

Video style

Audience: Users of MagicDraw SysML or Cameo Systems Modeler who are experimenting with creating custom stereotypes that extend Block.

This screencast video has been created to demonstrate some issues that can arise if you "naively" create a custom stereotype that extends Block without: (1) closing then re-opening your project; (2) creating an appropriate MD Customization. It is not about any actual "bug" in MagicDraw/Cameo (as long as you follow the recommended procedure). If you watch it, please do watch it to the end to find how to handle such stereotypes properly.

Screencast: MagicDraw SysML/Cameo: Pros and Cons of custom stereotypes in combination with Block inheritance and Part Property structures

Keywords

Video style

Audience: Users of MagicDraw SysML or Cameo Systems Modeler who are experimenting with creating custom stereotypes for SysML.

This screencast video has been created to illustrate some pros and cons of using custom stereotypes in combination with Block inheritance and Part Property structures, and demonstrates some possible "gotchas". It concerns especially use of custom stereotypes to indicate: (1) cross-cutting aspects such as model layer membership; (2) use of tagged values to carry per-Element metadata.
