In FME Workbench, source and destination data is represented by objects in the workflow. In the same way, both geometric and attribute restructuring are depicted by objects called Transformers.
A transformer is an FME Workbench object that carries out the restructuring of features. A number of different transformers exist to carry out different types of restructuring.
The layout of windows in Workbench may vary, but by default the Workbench navigation pane will have a tab labelled Transformers. Click this to view FME’s transformer list.
The list is segmented into descriptive category folders, but you can see the entire list by opening the All folder.
