Use this dialog box to map specific drawing attribute properties to specific feature class properties when you export to a geospatial format. for example, you could map the color RED to the string CLAY.
Property value mapping is available for three AutoCAD properties only: .COLOR, LINETYPE, and LINEWEIGHT.
The AutoCAD drawing attribute property value (left column) displays as COLOR Value, LINETYPE Value, or LINEWEIGHT Value, as appropriate. Select the check box next to each property value to map.
The target feature class property value (right column) displays the feature class property name you entered in the Feature Class Property Mapping dialog box.
