LayerScene is the newest member in extension warehouse
LayerScene is the newest sketchup extension that is compatible with SketchUp 2016, SketchUp 2017, SketchUp 2018. This sketchup extension is developed by Rafael Rivera.
The extension can be used to automatically generate scenes providing the names for every layer in your model as well as conceal entities on the basis of what layer they are situated.
The most crucial point is that the entities which pertain to a particular layer will only be viewed in the scene that is equal to that layer's name.
