The pick tools use the mouse buttons consistently to perform certain operations:
There are four different selection modes, which are described below. Use Preferences > Selection Options to assign a selection mode to each mouse button.
Choose between objects that are close together
If several objects are in the same space in a view window, it may be ambiguous which object you meant to pick when you click. In this situation, a pick chooser menu will pop up. Drag and release to specify the object you want to pick.
Pick a number of objects of the same type
Everything created in Alias has a name. You can see the default names of objects by opening the Object lister or SBD (Scene Block Diagram).
To pick a number of objects of the same type, use the command line and type the common part of the object names using wildcards for those parts that may differ.
The asterisk (*) is a wildcard that matches any character or characters. For example, if you have 50 spheres named sphere, sphere#2, sphere#3, and so on, to sphere#50, you can pick all of them by typing sphere* at the Pick prompt.
Enter name of item to pick/unpick: sphere*
Press (Windows) or (Mac) and all the spheres become active.
