A file opened in Arbortext IsoDraw will be displayed in a window. In most cases you will only be able to see a section of the illustration, particularly if you enlarge the illustration or move it around in the window.

All the information required to display a particular section of a file in a window is combined into a viewport. You can give a name to a particular viewport in order to be able to restore this status later with ease.

Viewports are particularly useful if you frequently change position on large illustrations. Arbortext IsoDraw lets you create a separate viewport for every important section, allowing you to switch backwards and forwards between these sections with a click of the mouse.

Viewports can also be used for interactive illustrations. Here, viewports are linked with hotspots which allow you to jump from one illustration to another (see the section on the Objects Menu).

The commands in the pop-up menu allow you to create new viewports and modify or delete existing ones. Every viewport is assigned a name which appears in the Viewports window.
