Picking and Unpicking Objects
Picking refers to selecting objects in the scene for use with other tools. For
example, to move a CV, you must pick the CV, then use the Move tool on
the picked CV.
Picking objects in the scene is a fundamental part of modeling with Alias.
Because it is so important, Alias provides several different tools for picking.
To pick all and pick nothing
1 In the Pick palette, choose Object Types > All Objects/Lights .
2 All the objects in the scene highlight to show they are picked.
