for Use Cases and Test Classes/Suites, Sparx EA does support a rectangle notation instead of the default elliptic appearance. (As described here: http://www.sparxsystems.com/enterprise_architect_user_guide/modeling_languages/usingrectanglenotation.html)
Is it possible to make the rectangular notation the [ EA-wide | project-wide | package-wide ] default for test classes/suites?
As no answer came in here, I posted the same question to the Sparx forum and a user answered it: You can use EA's API to achieve that, as there is no such setting.
