Restore Default Visibility of Layers

When you save a drawing, the data of visible layers is saved into it, if the setting Keep Layer Scheme Saved in Drawing is enabled. Next time you open the drawing, the layers are activated according to the saved information. If necessary, you can restore the layers defined as visible in the default layer scheme to be visible in the drawing.
  1. Select View | Layers | Layers > Edit.
  2. Select Restore visibility.
  3. Confirm by clicking OK.

In the Vertex BD application, you can also select Restore Default Layers from the tool strip.
