You can perform a number of zoom operations in [[EM.Cube]]'s project workspace. One of the most widely used tools is '''Zoom Extents'''. This tool automatically zooms to fit the whole structure into the main window. You can access this tool from '''Zoom Extents''' button [[File:zoom-to-extent_tn.png]] of '''View Toolbar''', or by using the keyboard shortcut '''Ctrl+E'''. Sometimes you may prefer to zoom on a certain part of a structure. In this case, you should use the '''Zoom Window''' tool, which can be accessed from '''Zoom Extents''' button [[File:zoom-to-area_tn.png]] of '''View Toolbar''', or by using the keyboard shortcut '''Ctrl+W'''. Once this tool is enabled, draw a selection box around all the objects that you would like to zoom to. The view size is adjusted to fit the selected area. You can also zoom to one or more selected objectsusing the '''Zoom Selected''' tool.

The size and boundaries of the viewport can be set manually via '''Menu > View > Viewport Properties'''. In the Viewport Properties Dialog, you can set the viewport size by specifying the coordinates of the "Top-Left-Near" and "Bottom-Right-Far" points. You can also set the coordinates of the viewing camera location.
