The Preferences Browser

The Preferences Browser

The Preferences Browser provides a means of setting preferences, or default properties, for the visualizations, annotations, and file readers and writers used by all iTools. For example, if you prefer the projection of contours displayed on surfaces to be three-dimensional rather than planar, you can change the default property for projecting contours from Planar to Three-D in the Preferences Browser, as shown in Figure 3-18.

For more information on the property sheets displayed in the right-hand pane of the Preferences Browser, see Visualization Properties.

The Preferences Browser displays a nested list of visualizations, annotations, file readers, and file writers available for all iTools in the left-hand pane, and a property sheet for the currently selected item in the right-hand pane.

To expand a list item, click the + icon

To collapse an expanded list item, click the - icon
