Attribute Name Values

An attribute name parameter has a value that can be either the name of an attribute or one of the special values below for accessing other fields associated with the feature:

  • <Feature Name> - the value is the display label of the feature
  • <Feature Type> - the value is the classification of the feature
  • <Feature Desc> - the value is the description of the feature (often the same as the feature type). For formats like DXF or DGN, this will be the DXF layer or DGN level name respectively.
  • <Feature Layer Name> - the value is the name of the layer that the feature is in
  • <Feature Layer Group Name> - the value is the name of the layer group that the feature is in
  • <Feature Source Filename> - the value is the filename of the file the layer was loaded from
  • <Index in Layer> - the value is the 0-based index of the feature in the layer that the feature is in. Note that area, line, and point features are separately indexed.
