Modeling from a SQL

Hi there I'm so nub at this DataBase Stuff And I'm lerning to use DataModeling software such Case Studio, but no matter how hard I search for this, I still can not find the solution I want:
I already have a MySQL DataBase, but I want to generate from there the entiy-relationship model.
Is there a way to do it in Case Studio????
Is there a way to do it at all???????

thanx for just listen.

Any coment will be useful, thank you.

can you clarify what it is you want to do? It isn't quite clear.

I have a SQL with the structure of a DB, a bunch of "Create table.... create index..." (no insert data querys, just the structure) and I want to import it to the Case Studio so I can make some changes in the desing and stuf.

Is it possible?

Is it possible to import a DB from a SQL archive to any DB Design Software?
