In AutoCAD 2008, new layer tools provide more control over your drawings. The first time you save or plot a drawing in AutoCAD 2008, AutoCAD automatically creates a layer list with all the existing layers in that drawing. From that point forward, any newly added layers will be regarded as unreconciled. A layer notification bubble in the lower right-hand corner displays a link, which opens up the Layer Properties Manager.
In the Layer Properties Manager, any layers that donât match the original layer list are displayed using a temporary layer filter for Unreconciled New Layers. You can review the unreconciled layers and choose whether you want to add them as valid layer names within the drawing. To add unreconciled layers to the layer list, you can simply select them, right-click and choose reconcile layer. Those layers are then included in the layer list and will no longer trigger the layer notification.
You can control the layer notification behavior using the Layer Settings dialog box, which is accessible from the Settings button in the Layer Properties Manager. In the Layer Settings dialog box, youâll see a section for New Layer Notification Settings. When you enable the option to have AutoCAD evaluate layers added to the drawing, you can choose whether you want to only evaluate new xref layers or if you want to evaluate all layers that are added to the drawing. You can specify if you want to be notified of new layers and when you want to be notified. For example, do you want to be notified when you open or save a drawing? Or when you attach or reload xrefs? In addition, you have the option to display an unreconciled layer alert when you plot.
