Translations:Create a FeaturePython object part I/8/en

The custom python class simply takes a reference to one of these objects and modifies it in any number of ways. For example, the python class may add properties directly to the object, modifying other properties when it's recomputed, or linking it to other objects. In addition the python class implements certain methods to enable it to respond to document events, making it possible to trap object property changes and document recomputes.
