This tutorial will help you start UML modeling in GenMyModel and will guide you step by step through the different common elements in the UML world. Most of actions in GenMyModel can be done using keyboard shortcuts.


Note : Unlike a simple drawing tool, GenMyModel relies on the UML 2.5 standard to help you create compliant UML models  


Create a new project UML project from the GenMyModel dashboard and choose Class diagram.



Once it's done, press the Open in Editor  button to open the GenMyModel work environment.
