Menus provide an alternative means of accessing Smart Isometrics commands. Similar or related commands are grouped together.
There is a lot of overlap between toolbars and menus and a tool or command works the same whichever way it is accessed. Find the method of working which suits you. Menu items usually have equivalent keystrokes, or hotkey combinations that can sometimes provide the most rapid way to access a command.
To toggle on and off the display of the Menu bar, select View > Toolbars Command > Menu Bar.
