Running C++-to-UML transformations in silent mode To prevent new dialog boxes from opening while a transformation runs, you can set the transformation to run in silent mode. If a reverse transformation is available and it supports silent mode, you can set the reverse transformation to also run in silent mode.
Running C++-to-UML transformations Before you can run a transformation, you must create a transformation configuration. When you apply a transformation configuration, an instance of the transformation is created and the transformation runs with the properties that the configuration defines.
