The term "parametric" in this context refers to the relationships among and between all elements of the model that enable the coordination and change management that Revit Structure provides. These relationships are created either automatically by the software or deliberately by the user as the user works. A fundamental characteristic of a building information modeling application is the ability to coordinate changes and maintain consistency at all times. The user does not have to intervene to update drawings or links.

At the heart of Revit Structure is technology that is new to structural design, engineering, and documentation systems: a parametric change engine. Revit Structure is built from the ground up using this technology. The Revit parametric change engine uses the information captured as you work to build a network of relationships between elements. When you change something, Revit Structure immediately applies that change to any related elements.

This concept is important because it is this capability that delivers the fundamental coordination and productivity benefits of Revit Structure: change anything at any time anywhere in the project and Revit Structure coordinates that change through the entire project. This parametric change management is also one of the fundamental characteristics of a building information modeling solution.

Revit® Structure software integrates a multi-material physical and an independently editable analytical model for efficient structural analysis, design and documentation.

Improve coordination with architects using AutoCAD® Architecture software or Revit® Architecture software. Parametric change management and bidirectional linking to structural analysis software means automatic updating across your documents for the most accurate model refinements.
