The Layers tab lists the layers displayed in the graphics area of a drawing document.
The initial state of layer display reflects how documents were saved in the original document.
Resaving documents in SolidWorks eDrawings saves the layers in their initial state.
Hidden annotations and dimensions and empty layers are included.
Layer states apply to the whole document, not by sheet or view.
Markups capture the state of the layers, so if a markup is retrieved, layers are displayed as they were when the markup was created.
Shaded data for components in assemblies is published with the layer data.
