Describe a bit more of what you are trying to do...
Frame inside enclosure walls with windows and doors and furniture sitting on a landscape?
Layers can work ... but be warned - they DO NOT CONTROL geometry - so only move groups and / or components to a layer other than Layer 0. What this means is that if you are a sloppy draftsman - when you switch off a layer part of your model may disappear - obviously the intended effect - except when half a timber or half a wall disappears. Ungrouped and uncomponented(?) Lines drawn on a layer CAN influence other stray lines that may be turned 'off'. My practice is that I only move components and groups to layers.
The Outliner is your friend here - along with groups and components and scenes.
The way I work is this:
Lines and planes get made into components - these become timbers, rafters, floor joists, walls, windows, etc. - basically the 'objects' that we build with.
Components get organized by groups - so timbers may be grouped as 'Roof', 'Floor', or B1, B2, Wall A, etc. etc. Walls get the same treatment, and I usually include windows in the grouping of the wall geometry.
(Note - in the case of a group that could be repeated I would make it a component - so a truss that repeats would probably become a component rather than a group so I can make changes throughout.)
When I have my model working along I'll use a combination of the outliner and scenes (with layers as needed).
The outliner lets you control the groups and components, and the parts within them. When you open the outliner you can effect your model by right clicking items - so Hide, Unhide, Delete, select, filtering, etc. etc.
A strategy you might use is to put objects 'X', 'Y', and 'Z' into different macro groups (with micro and sub groups and components within them). You can now control visibility of single objects or whole assemblies.
If you keep coming back to a certain part, object, or view - create a scene. This will create a tab on top of your model view and allow you to keep coming back to it. You can have the scene 'remember' exactly what you are looking at - so section cuts, objects that are hidden, layers, camera angles, etc. etc.
I use layers only for objects that may want to be on or off as they cross over groups and large assemblies - and most of my layering is for 2 purposes - documentation (dimensions, notes, construction lines, etc.) and for 'fluff' (people, cars, trees, furniture, - stuff that dresses up the model)
Hope this helps.
