CAD drawing layers are layers that exist in the source CAD drawing. When you add CAD data to a map document, layer settings in the CAD file determine their default visibility in ArcMap. You can change these settings in the Layer Properties dialog box and save them as properties of the feature layer.
To open the dialog box, double-click the CAD feature layer in the table of contents, or right-click the layer and click Properties on the context menu.
Drawing layers tab
Each CAD feature layer maintains its own collection of visibility settings in the Drawing Layers tab. You can set them differently across multiple feature layers in the same map (.mxd) document.
