Impact Explorer - Drawings Hierarchy
The icons indicate whether each drawing is a project 
or symbol 
. Similarly the layer icons indicate a one-up layer 
, a multi-up layer 
or a 3D layer 
. A disk icon 
is shown beside any drawing and layer that contains unsaved modifications.
The current drawing is shown in bold. The current layer is highlighted. Simply click on any drawing or layer to make it current. When making a layer current there are special key functions available as described in the Layers page - Special keys.
The display format of the layer name can be defined in the Environment > Database Operation > Display.
