Generative Shape Design workbench

In CATIA, when working with the Generative Shape Design workbench, how can you ensure that a swept surface maintains G2 continuity with adjacent surfaces, and what specific tools or methodologies within CATIA would you use to achieve this level of continuity?
Accepted answer

Very broad question. Do you have a specific example?
How to maintain G2...
a) make sure any curves used are G2 or higher
b) use surface tools that can construct G2+ joining surfaces
If the tool you're using, does not allow G2+ continuity control, don't use it.
Use analysis tools to ensure the continuity requirements/tolerances are met.
You'll need to get much more specific if you want better answers. Else we can assume you have patch A and want to connect patch B. That's usually not where the real difficulties lie.
