To change common attributes all at once, you can select all the parts that have the same features.
Click the [Properties] tab in the Work Space.
If the [Properties] tab is not displayed in the work space, from the [View (V)] menu, point to [Work Space (W)] and select [Properties (P)].
While holding the [Shift] key, use the mouse to select the object that you want to change its attributes.
The setting detail displays when the items have the same setting. When they differ, a blank space displays.
When you enter a setting in the blank space, the attributes for all the selected parts change to that setting.
Depending on the shape of the switch lamp parts, you may not be able to change the color all at once.
When you select various types of objects or select grouped objects, you can only change their coordinates.
