In this case, the parameter is not a number but a proportional characteristic. If the length of the elevation is changed the relationship of equal spacing is maintained. Another example of a parametric relationship would be windows or pilasters spaced equally across a given elevation. If you move the partition the door retains this relationship to the partition. For example, let's say you want the outside of a doorframe to be a fixed dimension on the hinge side from a perpendicular partition. This capability delivers the fundamental coordination and productivity benefits of Revit Architecture which is change anything at anytime anywhere in the project, and Revit Architecture coordinates that change through the entire project. That is why the operation of the software is Parametric. In mathematics and mechanical CAD the numbers or characteristics that define these kinds of relationships are called Parameters. These relationships are created either automatically by the software or by you as you work. The term Parametric refers to the relationships among all elements of the model that enable the coordination and change management that Revit Architecture provides. The Revit Architecture Parametric Change Engine automatically coordinates changes made anywhere in Model Views, Drawing Sheets, Schedules, Sections, and Plans. As you work in Drawing Views and Schedule Views, Revit Architecture collects information about the building project and coordinates this information across all other representations of the project. In the Revit Architecture Model, every drawing sheet, 2D and 3D view, and schedule is a presentation of information from the same underlying building model database.

Building Information Modeling delivers information about project design, scope, quantities, and phases when you need it. The Revit Architecture platform for building information modeling is a design and documentation system that supports the design, drawings and schedules required for building projects. You will then learn the Terminology, the Hierarchy of elements, and how to perform some common tasks in the product. You first begin with the fundamental concepts on which Revit Architecture is built.

In this lesson you will learn what Revit architecture is and how it's Parametric Change Engine benefits you and your work.
