Properties button
The Basics: Placing and Editing Transformers
There are many ways to place a transformer on the Workbench canvas. To start, however, you can simply
double-click the transformer name and it will appear in the workspace.
Every transformer has a Properties button on the right of the transformer.
This button is color-coded to show the status of the settings.
ƒƒ If the Properties button is the same color as the transformer, you can use the transformer with
its existing parameters.
ƒƒ A yellow Properties button indicates that the transformer contains default settings, but you
have not yet accepted them. You can use the transformer in this state, but your workspace may
produce unexpected results.
ƒƒ A red Properties button means that there is at least one parameter for which FME cannot
supply a default value. You must provide a value for all required fields before you can use
the transformer in the workspace.
When you click a Properties button, the dialog that appears will usually have some of the common elements
shown in this example. The content of this dialog depends on the transformer, and sometimes even on
connections to the transformer. Most transformers have some common user interface elements, however,
and those are described here.
What is a Transformer?
A transformer is an FME Workbench object that carries out the restructuring of features. FME contains
over 400 different transformers to carry out different types of restructuring. In the Workbench interface,
transformers are stored in the Transformer Gallery and grouped in categories applicable to their
associated functionality.
You can edit the default
transformer name.
Many transformers
allow you to group
results according to
selected attributes.
Required fields are
highlighted. If this field
is not filled in, the OK
button is disabled.
Click OK to accept
changes and close
the dialog.
(This button is
disabled if required
fields have not been
populated.)The Defaults menu allows you to replace FME
defaults for this transformer with your own
parameter defaults. You can always reset the
dialog to FME defaults.

Extruder Creates long, surface or solid
geometries with a fixed crosssectional
profile taken from the

be reversed. On solids, it will reverse the underlying surfaces, in effect
causing the solid to be turned inside-out.
