What Is Meant by Parametric?

The term parametric refers to the relationships among all elements of the model that enable the coordination and change management that Revit provides. These relationships are created either automatically by the software or by you as you work.

In mathematics and mechanical CAD, the numbers or characteristics that define these kinds of relationships are called parameters; hence, the operation of the software is parametric. This capability delivers the fundamental coordination and productivity benefits of Revit: change anything at any time anywhere in the project, and Revit coordinates that change through the entire project.

The following are examples of these element relationships:
