Our 3SL colleagues in the US have posted a series of videos demonstrating the SysML support in Cradle-7.1. This is a single demonstration, split into a series of parts:
You can access these demonstration videos here:

Please look at these videos and see how SysML models can be built in Cradle and how these models can be integrated into other information, including requirements, tests, test cases, defects, issues and risks.
At 3SL we believe that MBSE is the ideal approach (whichever notations you choose to use) but only if it is integrated into all of the other information in your project.
MBSE in isolation is just a bunch of pretty pictures!
