Object Selectability Controls
You can control selectability of objects by using the Layers panel in the Palette assistant and by using the selection protection commands.
The Layers panel lets you control the selectability of all objects on specific layer-purpose pairs. For example, the figure shows that selectability setting of the Nhvt layer-purpose pair is turned off, which implies that its objects are not selectable on the canvas. You can use the S (Selectability) check box and the AS and NS control buttons to define the selectability setting for layer-purpose pairs.
To set individual objects as selectable or unselectable, use the selection protection commands. In Layout Viewer, you can access the commands from the View – Select menu. In Virtuoso Layout Suite XL and higher tiers, you can access the commands from the Edit – Select menu.
The following table describes the commands. These commands work in both pre- and post-selection modes.
