Crocus Modeller is designed to work with AS3 and Flex projects. It supports all important language features, such as packages, inheritance, getters/setters, static & constant variables, etc...
After creating your diagram you can generate AS3/Flex code stubs. Don't waste your time on writing a dull code, focus on what really matters.
It's much easier to understand a project by viewing its class diagram, rather than reading the source code. Crocus Modeller allows you to generate a diagram from your project's source code, so you don't have to create a diagram by yourself.
No more typos. Crocus auto-completes AS3, Flex and your custom types for you.
