The MGE Reader extracts all elements from the design files, one at a time, via the help of the Design File Reader. For each element, it finds every attached feature and passes each on to the rest of the FME for processing, along with any corresponding non-graphical attributes. Complex elements are extracted as single FME features. If the element has any attribute linkages attached to it, these are read in and added as attributes to the FME feature created.
When the MGE Reader encounters an element type it does not recognize, it is processed as an “unlinked” element type.
