Why Astah after all these other modeling tools? Overall: My overall experience with Astah has been very good over the years and I will continue to use the tool in coming years. Pros: Today, when using a modeling tool, my primary concern regards the usability of the tool. If I need to model something quickly then I want to be able to get my ideas onto a canvas quickly and easily. The last thing that I want to do is to wrestle with the tool as my ideas and thoughts float away.The installability of the tool is really good as well as I never have any issues with updates/upgrades and they are always welcome as I know the vendor always adds some new feature that I didn't know that I needed. Cons: One of my biggest complaints about Astah has been its lack of good and reliable reverse engineering, specifically with C++. Another feature that I wish was improved is the sharing of models and I don't believe that the current feature is good enough.
