Modelio features

The most important features of this all-in-one UML modeling tool

The functional and ergonomic richness of Modelio will amaze you!

It may take you some time to discover all Modelio's many features, but you'll immediately feel its simplicity thanks to its well-known RCP/Eclipse-style ergonomy. And don't forget that using the (MDA) module technique, Modelio can be configured for specific kinds of use in your own individual context.

It would be almost impossible to provide an exhaustive list of all Modelio features, but the table below presents some of the most important ones, organized by theme.
