When you draw in SU are you not drawing only on the Active Layer? Yes. You are drawing on the active layer.
Does this mean that you draw an object on layer 0 the[n] change the layer when you make it a component? Yes. Draw an object on Layer 0 (Draw all objects on Layer 0). After you made your components, use the Entity Info box to move those components to layers as desired.
I think it would solve some visibility problems I have had that evan if I move a component to another layer the layer that was active when I first made the component must be visible to make the component visible. Unless you move the geometry inside the component to the same layer as the component, hiding the layer that was active when you drew the geometry, will hide the geometry. This is actually where the problem comes in when you start making other layers active. It is too easy to lose track of which layer you drew the geometry on. Suppose you have Layer 1 active but are editing a component on Layer 2. And suppose you later decide to turn off the components that reside on Layer 1. The geometry in the component on Layer 2 that was drawn on Layer 1 will also be turned off.
If you end up with geometry on different layers, you end up with quite a mess. The easiest way I know to fix that mess is to delete all of the layers. When you delete layers you are prompted to choose whether or not to delete the geometry on the layers or move it to the active layer.
What you really end up doing by keeping Layer 0 active and moving only components (or groups) is leaving all geometry on Layer 0. Only the components get moved to other layers. You can't turn off the active layer but it doesn't matter this way. If you turn off a layer's visibility, you also hide the geometry in that component.
There's really no point in moving the geometry to different layers since you only need to move components. If you move all the components in your model to other layers, turning off all those layers will leave you with a blank screen.
Does that make any sense?
