Typically your layers should be managed so they will screen different objects from other objects. For example, text should be on one layer so that you can turn it off and on and not affect anything else. Same for dimensions. Same for different blocks. (I don't know what your discipline is but mine is mechanical design, so I have valves on one layer, pumps on another, and certain instrumentation on their own individual layers.)
It also helps to make the layers different colors so you can quickly identify which layer an object may be on. If you google layer management in CAD, you will get some hits for proper layer management and even some video tutorials. I commonly use DOT layer management since I don't have to re-create the wheel. They will designate layer names, colors, linetypes and even line weight. (I don't use line weight much. Everything is basically the same in my drawings, unless I use a Pline with a width in my titleblock.)
Once you have your layers set up, to designate every layer you will need for your drawings, then you can select a layer and start drawing that object and all attributes will be correct. You should never use overrides by using the individual object properties toolbar unless necessary. (Such as changing a solid line to a phantom line because of a need to show movement/rotation or something alone that line.) This practice of using the overrides will only complicate things if you decide to turn off every layer except a few or one. Then you will have objects all over your drawing, which you wish were turned off but they aren't because they are all on the same layer, just different colors. Keep your lines type, color and weight set to "by layer".
I hope this explanation helps to answer your question.
