Can anybody explain me abt rigid/flexible sub assembly in assembly design

I just want to know how to use it n wats the purpose of using it

If you are using the same subassembly more than one time, you Mighty get problems, because all CATParts in the subassembly get the Same orientation. These subassembly have to get flexible.
Example: Engine with four subassembly of piston, rod, bolt, ...
Every piston has a different angle to the rod, they Must be flexible.
