In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).
TFS Variable Schema features consist of geometry, a special predefined attribute, and a set of user-defined attributes. All TFS Variable Schema features have one predefined attribute, tfs_type, which identifies the type of the feature’s geometry.

tfs_type |
This attribute will contain one of: tfs_point tfs_line tfs_polygon tfs_arc tfs_text tfs_multi_text tfs_ellipse tfs_collection tfs_surface (C++) tfs_solid (C++) tfs_null Default: No default |
Arcs
tfs_type: tfs_arc
Features with a tfs_type of tfs_arc contain arc geometries. Arc geometries can be defined as elliptical arcs by center point, arcs by bulge with start and end points, and arcs by start, mid and end points.
Collections
tfs_type: tfs_collection
Features with a tfs_type of tfs_collection contain a combination of other geometries. The combination of other geometries form a non-homogeneous aggregate geometry.
Ellipses
tfs_type: tfs_ellipse
Features with a tfs_type of tfs_ellipse contain ellipse geometries. Ellipse geometries are defined with an arc geometry as its boundary.
Lines
tfs_type: tfs_line
Features with a tfs_type of tfs_line contain line, path, or multicurve geometries.
Multitext
tfs_type: tfs_multi_text
Features with a tfs_type of tfs_multi_text contain multitext geometries.
Nulls
tfs_type: tfs_null
Features with a tfs_type of tfs_null have no geometry associated with it.
Points
tfs_type: tfs_point
Features with a tfs_type of tfs_point contain point or multipoint geometries.
Polygons
tfs_type: tfs_polygon
Features with a tfs_type of tfs_polygon contain polygon geometries. Polygons have an outer boundary and may or may not have one or more inner boundaries defining a hole in the polygon.
Solids (C++ TFS Variable Schema)
tfs_type: tfs_solids
Features with a tfs_type of tfs_solid contain solid geometries.
Surfaces (C++ TFS Variable Schema)
tfs_type: tfs_surface
Features with a tfs_type of tfs_surface contain surface geometries.
Text
tfs_type: tfs_text
Features with a tfs_type of tfs_text contain text geometries.
