Element.Parameter(BuiltInParameter)

Property
Description:
Retrieves a parameter from the element given a parameter id.
Remarks:
Parameters are a generic form of data storage within elements. The parameters are visible through the Autodesk Revit user interface in the Element Properties dialog. This method uses a built in parameter id to access the parameter. Autodesk Revit has a large number of built in parameters that are available via an enumerated type.
