Element

Description:
Base class for most persistent data within a Revit document.

Remarks:
The data in a Revit document consists primarily of a collection of elements. An element usually corresponds to a single component of a building or drawing, such as a wall, door, or dimension, but it can also be something more abstract, like a wall type or a view. Every element in a document has a unique ID, represented by the ElementId class.
