Remove Selected Objects from Contour Sets
(3D mode only) Use this command to remove the selected objects from all contour sets they belong to. The Remove selected objects from contour sets command is also available on the context menu when you right-click a selected object, and on the Contour Sets attribute window menu.

You do not have to activate a contour set to remove objects from it. This command removes selected objects from both the active contour set and inactive contour sets.
