Overall, there are three element types in Revit

Element Type Description

Model elements Are elements that represent the model's current 3D geometry,
for example. walls, Windows, doors and tag the Model
elements.
Datum elements Are reference points in the project, which define building
model's placement. Floor levels, module lines and reference
plans are the Datum elements.

View specific elements Are elements which are seen only in the viewsin which they are
located in. It is items that are part of the documentation, such
as dimensions, tags and 2D detail components.
Breakdown of element types

As shown by the flow chart, there is a furtherbreakdown by Model elements and View-specific
elements.
Model Elements Description

Host Elements, modeled in the project, for example. walls, decks,
roofs, and ceilings that create the basic geometry or structure
in a building.
Component All other elements of the building, such as Windows, doors and
furniture.

View-specific elements BDescription
Annotation 2D elements, such as dimensions, text, style, etc. Size of
these elements follows the scale of the view.
Details 2D objects, that in the current views shows detail in the
project, for example. detail lines, extra shading (Filled Region)
or 2D detail components.

Elements are objects – Revit is object-based.
This means that the objects, which is being used in Revit, has a specific function in the project.
A wall "know" that it is a wall, and it is therefore able to link up with other walls, and it is able to
"host" a door or any kind of opening.
Walls are also able to include information about the material, fire function and much more, while
the ventilation channel can contain information about airflow, air velocity, pressure loss and
isolation. This information is stored in the object and interact with the rest of the project, after
loading object in your project.
