If you just created your first project, the only opened window (apart the LivePage) of the project is the Layout. So you need to open the Navigation window once you want to start seeing the project in 3D. You can do this in 3 different ways:
1. Select the Navigate button available in the Ribbon (refer to Virtual Navigation group)
2. Use keyboard shortcut Shift + F6 (unless you have customized it in a different way)
3. Click the right mouse button wherever (apart on the existing entities) in the layout desktop, and select command Virtual navigation.
If the Navigation window is already opened, by selecting one of the aforementioned commands will not open a second navigation, but will make the existing one visible top of windows.
Please, note that you do not have to close the Navigation window once you go back to the layout; you can leave it opened and keep on working in the layout or the tiling window. While hidden, in fact, the Navigation window will not use any resource of your computer, and will automatically update itself with the project news once you will make it visible again.
Finally, Ctrl+Tab is a very useful shortcut that allows you to switch between the opened windows in the Application.
