Engines | Assembly | Pick

This option is used to pick an object in the viewer window. Please note that pick fails when the scene graph has LOD nodes. This problem can be overcome by removing the LOD nodes in the scene by applying Tools | Clean LOD. After picking, the mouse will be in Track Ball mode that is focused only for the selected Shape, until you apply

Engines | Assembly | Unpick
