Hi Tudor,

re:

A .commit() is expected to be the last thing that is called on a factory, it is a signal to MoI that the work being done for the factory with updating different inputs is all finished.

If you want to get the objects that will be generated, you can instead call .update() and then .getCreatedObjects(). Or it is also possible to call .calculate() which will generate the result and return it as an object list without adding it in to the geometry database like usually happens in regular commands with .update()/.commit()/.cancel() .
