Use pick conventions
 
 
 

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.

Selection mode What it does

Toggle

This is the defaut for the

Switch the object(s) between picked and unpicked.

Add

This is the default for the

Pick the selected object(s). What is already picked remains picked.

This mode is useful for composing a collection of objects to be used for a variety of operations including grouping, assigning materials, and transforming.

Unpick

This is the default for the

Unpick the object(s).

Pick

Pick only the selected object(s).

This mode is useful when picking controls for direct manipulation, as we only want one control to be picked at a time.

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.

  • The * can appear anywhere in the wildcard expression. For example, sphere*5 picks every sphere whose name ends with 5.
  • The ? (question mark) is a wildcard that matches a single character. For example, t?p matches objects named tip, tap, or top, but not trip.

What if...?

I want to pick multiple objects in the “pick chooser” menu?

Press and click each object name in the list.
