The Layers in the View Manager are different from the Layer Tree. I think you what to use the layer tree. The other option is to use Simplified Reps to hide the components for the drawing. I would suggest Simplified Reps as this allows all of the layers to be hidden for the drawing, which is standard practice at most companies. The layer tree gets complicated in assemblies if there are many odd layers that contain parts of models or assemblies. Layers are ussually used for datums and reference items.
