In most transformations, there is a lot of information that is simply copied to the target model.  In order to make writing new transformations simpler Enterprise Architect provides a default set of transformation templates.  These templates perform a simple copy of the source model to the target model.  This means that in order to write a new transformation you can modify the default templates to make the required changes.

Note: When creating a new transformation you must modify at least one template before the transformation becomes available.
