This document describes the basic principles of plugin/feature system and shows how to use the API for writing a feature or plugin. Currently, the API is available for C++ and Python languages. Plugin, written in C++ is a shared object (dll); For Python, it is regular python module, with *.py extension.

\code
void ConstructionPlugin_Point::initAttributes()
{
- data()->addAttribute("DoubleCounterData", ModelAPI_AttributeDouble::type());
+ data()->addAttribute("DoubleCounterData", ModelAPI_AttributeDouble::typeId());
}
\endcode
Python:
\code
def initAttributes(self):
- self.data().addAttribute("DoubleCounterData", ModelAPI.ModelAPI_AttributeDouble.type())
+ self.data().addAttribute("DoubleCounterData", ModelAPI.ModelAPI_AttributeDouble.typeId())
\endcode
As you may notice, this method defines that feature has a widget with "DoubleCounterData" id, which has Double type. Therefore, if your feature uses, in example, three widgets, the `initAttributes()` method should 'init' three attributes.
