In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described in this section.
Facet features may consist of geometry and attributes. When reading Facet files, several special attributes hold the data from the file. When writing Facet files, the values in these attributes are written out to the file. If the feature does not have these special attributes, appropriate default values will be used.
Special supported Facet format types include: text, line, polygon, multipoint, point, or database.
Note: Multipoint data may contain a single point. Also note that database features contain attributes but no geometry.
All Facet features produced by the FME reader contain the facet_fme_type attribute, which identifies the geometric type. Depending on the geometric type, the feature contains additional attributes specific to the geometric type. These are described below.
|
Attribute Name |
Contents |
|
facet_fme_type |
The Facet geometric type of this entity. Values: facet_multipoint facet_line facet_polyogn facet_text facet_database |
Points
facet_fme_type: facet_multipoint
A Facet multipoint feature specifies single or multiple 2D or 3D coordinates. There are no special attributes with this type of feature.
Lines
facet_fme_type: facet_line
Facet line features contains 2D or 3D linear geometry. There are no special attributes with this type of feature.
Polygons
facet_fme_type: facet_polygon
Facet polygon features contains 2D or 3D geometry. Polygons may be either simple or may contain holes, thereby being donuts. There are no special attributes with this type of feature.
Text
facet_fme_type: facet_text
Facet text features contain 2D or 3D coordinates and a text string, along with the text alignment, rotation, and size.

Attribute Name |
Contents |
|
facet_text_string |
The text string. Range: any length character string Default: empty string |
|
facet_text_alignment |
A numeric code indicating the feature’s alignment. Several settings are listed below. These settings may be ANDED together to form a single numeric code: TextAlignLeft 1 TextAlignRight 2 TextAlignCenter 4 TextAlignBase 16 TextAlignHalf 32 TextAlignCap 64 TextAlignTop 128 TextAlignBottom 256 Range: 0 - 511 Default: 0 |
|
facet_rotation |
The rotation of the text, measured in degrees counterclockwise from the horizon. Range: any real number Default: 0.0 |
|
facet_text_size |
The size of the text. Range: any real number Default: 1.0 |
Database
facet_fme_type: facet_database
Facet database features contain no coordinates. These features may contain any number of custom attributes. There are no special attributes with this type of feature.
