Not any that I know of.

The Eclipse platform has UML modeling support so I would expect that we will want to integrate with that in a future release of our Eclipse plugin, but are not working on that currently. I would expect that it would not be too difficult to at least generate UML models from Curl source code, and that would be a very useful alternative to our class browser. Code generation would be much more difficult -- at least to do it right. Speaking for myself, I question the usefulness of model-based code generation, since I have had discouraging experiences with it in the past. In any case, now that we are going to be supporting Eclipse, there is nothing to stop interested third parties from developing their own Curl UML plugin for Eclipse if they don't want to wait for us to do it.
