Translations:Create a FeaturePython object part I/9/en

It's important to remember, however, that for as much as one can accomplish with custom classes and FeaturePython objects, when it comes time to save the document, only the FeaturePython object itself is serialized. The custom class and it's state are not retained between document reloading. Doing so would require embedding script in the FreeCAD document file, which poses a significant security risk, much like the risks posed by embedding VBA macros in Microsoft Office documents.
