Layer Management > Enable (Manage Menu)

This command can be used to enable layers by identifying objects that are assigned to the desired layers. To enable a layer means to clear the attributes "Lock", "Ignore" and "Shade Down", i.e. the layer will be displayed in its original color(s) again, objects assigned to it can be chosen and will be considered during snap point detection. In addition, the attribute "Output" is set, so this layer will be printed and copied to the clipboard again.

Choose the objects whose assigned layers are 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 affected layers are enabled.
