Layer Management > Hide All Except (Manage Menu)

This command can be used to hide layers by identifying objects that are assigned to layers that are not to be hidden. To hide a layer means to clear the attributes "Display" and "Output", i.e. the layer will neither be displayed on screen nor output to printer or clipboard.

Choose the objects whose assigned layers are not to be altered. Click on objects to choose them, including objects in locked layers.

After identifying the objects, their layer assignment is determined and all non-affected layers are hidden.
