Case Tools

[crushbox311]

I was wondering if anyone new of a website where I could get some free case tools. My instructor assigned a mailflix assignment just like netflix and were going to have to create multiple classes. What I'm wanting is something to brainstorm ideas for my classes like a tree diagram where I can type in the name of the project and then branch out with class names and then branch from there to member functions. Also I need to be able to take those ideas and generate code from them. If anyone has anything in mind please let me know.I am now past the point in my programming carrer where I could just sit down and start writing code. I'm going to have to brainstorm ideas and then create code from those ideas. Thanks in advance for your ideas. P.S. They don't have to be specifically for computer design I just need some brainstorming tools.
