Makes the specified number of copies of the input features and outputs all copies through its single output port.
Feature cloning happens automatically in Workbench whenever more than one connection is made from any output port of a transformer. This transformer can be used to make a dynamic number of copies of a particular feature.
Parameters
Number of Copies
Specifies how many copies will be made of the input features. The number of copies may be a constant integer, or it can be taken from the value of an attribute on the feature by selecting the attribute from the pull-down list.
If the number of copies is less than 1, then the feature will be deleted.
If the number of copies is set to 1, then the transformer acts as a "null" operation and is useful to provide a place to connect several inputs together and join them into single stream of features to be routed elsewhere.
Copy Number Attribute (optional)
The copy number attribute (by default, _copynum) will hold the copy number of each output feature. For example, if 3 copies of an input feature are made, the output copies will have 0, 1, and 2, respectively, assigned to their copy number attribute.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
