Line entities are represented in the CCOGIF file as a Line Fixed-Length Record (LFLR) and optionally, a Line Variable-Length Record (LVLR). The FME combines the contents of these two records into a single feature—the line entity feature.
The geometry of FME's line entity feature is the line's coordinates from the LVLR. A Z-value of -9999 represents an undefined value, so any LVLRs that have Z-values of -9999 are translated as (x,y) coordinates instead of (x,y,z) coordinates.
In addition to the geometry and attributes common to all entity features, which were listed in the previous section, line entity features have the following attributes defined:
