== A summary of non-rooted elements ==

There are far too many ''non-rooted'' elements to list in totality, however a curated selection as shown below give a indication of the types of data that are stored in an IFC file, which can be reused by ''rooted'' elements.

! Description
|-
| <code>IfcMaterial</code>
| A material may be named, and then have further ''non-rooted'' classes assigned to it, such has simple RGB colours, textures, and material properties for environmental simulations.
|-
| <code>IfcCartesianPoint</code>
| As you might expect, IFC can store 2 or 3 dimensional Cartesian coordinates. This is one of the building blocks of many other ''non-rooted'' classes, such as the ability to locate an object in space, or build up geometric representations.
|-
| <code>IfcFacetedBrep</code>
| A huge variety of geometric forms may be described in IFC. One commonly known format is a faceted BREP, or series of polygons that describe the surface of an object.
|-
| <code>IfcPerson</code>
| Information about people and organisations can be recorded, which is especially useful as some countries have legislation that requires this to be stored.
|-
| <code>IfcPropertySingleValue</code>
| This commonly used class can define a single property in terms of a property name and its associated value. In addition, there are other classes that allow more complex properties in tabular or calculated form to be stored.
|-
| <code>IfcObjective</code>
| This little-known class can store design intentions, strategies, and objectives to be then associated with objects or portions of the BIM model.
|-
| <code>IfcRegularTimeSeries</code>
| When scheduling, events may occur at predictable time intervals, which may be stored.
