Changes

You can close a project at any time using the menu item '''File → Close Project'''. A message pops up that prompts if you wish to save the existing project. You can quit the [[EM.Cube]] application using the menu item '''File → Quit''' or using the keyboard shortcut "Ctrl+Q". Note that when you close a project, you are still in the [[EM.Cube]] application. If you start a new project, you may still carry some of the program settings from the previous project. Quitting and exiting the application ensures that all the default settings would take effect the next time when you start a new project.

You can also split the main window into multiple viewports. This provides simultaneous Perspective, Top, Front and Right views in the Project Workspace. To split the view, click the '''Split Viewport''' [[File:four-port-view_tn.png]] button of '''View Toolbar'''. Each viewport’s settings can be changed individually. The name of the active viewport on which changes apply is always highlighted with a dark blue background; inactive views are indicated by a gray background. In the Four-Port View mode, you can zoom extents for all four view at the same time by right clicking the '''Zoom Extents''' button [[File:zoom-to-extent_tn.png]] of '''View Toolbar''', or by using the keyboard shortcut '''Ctrl+Shift+E'''. You can always return to the single-port view at any time. To do so, click the '''Merge Viewport''' [[File:single-port-view_tn.png]] button of '''View Toolbar''' or use the keyboard shortcut '''End'''.
