Data Exchange Platform

ReUniXchange is a cutting-edge Revit plugin that enables seamless export of BIM geometry, metadata, and materials to Unity. It supports modular construction workflows and immersive XR applications by bridging the gap between design and visualization environments. The plugin allows users to assign shared parameters (ModularID) to Revit group components, extract structured metadata into CSV format, export 3D views as OBJ files with MTL and texture data, and re-import any changes made in Unity through an XML file.

For modular projects, the plugin can automatically generate ModularID parameters based on group names, enabling logical tracking and reconstruction of elements inside Unity. Metadata from Revit views can be exported to CSV and attached to 3D objects inside Unity to enable semantic enrichment, selection, and inspection during runtime. Material definitions used in Revit are also exported into Unity-readable MTL files with associated texture images.
