# Introduction

The Geometry Gym Revit plug-in for grasshopper allows for the parametric generation of native REVIT files and family's within the grasshopper environment. The REVIT plug-in comes packaged with the IFC plug-in and shares a lot of the same functionality.

The REVIT plug-in has been developed to provide a simplified model creation tool specifically for REVIT, utilising typical REVIT type names and functions without the need to set-up sometimes complicated relationships and project definitions required within the IFC plug-in.

## User Interface

The image below highlights the REVIT plug-in interface within the grasshopper environment.
