Layers in SketchUp work very differently from most CAD packages. Thin lines are used when all the faces attached directly to those lines are truly geometrically inter-connected. You may notice that there are two types of lines used in a SketchUp model: thick and thin lines. However, deleting a single face does not delete any of the edges that define it. Faces depend on the lines that define their edges, so that deleting an edge also deletes any faces that use that edge to define their boundary. For all SketchUp models, lines form the basis of geometry as they connect together in 3D to provide a framework for faces, which are in turn attached to those lines. The key to SketchUp modeling lies in the geometric topology of the two basic drawing elements: lines and faces.
