Autocad - Gestion de calque - État de calques

When working on a complex drawing, you sometimes need to turn off or freeze certain layers and change the properties of other layers. If you want to return to this set of layers and their properties, using layer states will make it easier. A layer state is like a snapshot of the layers and layer settings that existed at the time it was created. A layer state is saved in the drawing and can be restored at any time. You can also export the layer state and import it into another drawing.
