Visual UML 2.5 for Visual FoxPro is now available! It supports full round-trip engineering including code generation and reverse engineering (even creates brand new models from existing source code). All the issues with Inheritance Support that were there in version 2.0 have been fixes also.
Of course, Visual UML still supports the entire UML specification, and is an easy to use, straightforward tool... yadayadayada <s>.
Anyway: You can find more details at
