## Opening an existing model To edit a model that you previously created or that you received, you need to navigate to the `File -> Open` menu (Shortcut `Ctrl+O`) and select a file on your computer. A project that was recently opened can be accessed by navigating to `File -> Recent projects` and selecting one from the list. In order to create a new model, you can easily navigate to the `File -> New` menu item or simply hit the keyboard shortcut `Ctrl+N`. ![](GUI_FileNew.PNG "")
