Geometry Gym – Rhino Tools for BIM & Geometry

Geometry Gym is a powerful suite of BIM (Building Information Modelling) and structural data exchange tools for Rhinoceros 3D and Grasshopper. It enables professional architects, structural engineers, and BIM managers to manage complex geometric data and maintain absolute interoperability across the industry’s leading BIM platforms, including Revit, ArchiCAD, and Tekla.

By leveraging the Industry Foundation Class (IFC) standard, Geometry Gym allows for the creation, manipulation, and extraction of data-rich BIM objects directly within the Rhino environment. This makes it an indispensable tool for computational designers who need to bridge the gap between complex freeform geometry and professional, standard-compliant construction documentation.

Full IFC Support & Interoperability

The core strength of Geometry Gym lies in its comprehensive support for the IFC standard (including IFC 2x3 and IFC 4). This allows for the seamless exchange of high-quality NURBS geometry between Rhino and industry-standard BIM platforms with no data loss. Whether you are importing structural models for analysis or exporting complex facades to Revit, Geometry Gym ensures that your parametric data remains intact and actionable throughout the collaborative design process.

Advanced Grasshopper BIM Authoring

Geometry Gym provides an extensive library of over 690 specialized Grasshopper components, allowing you to author and manipulate BIM data via visual programming. This enables the automated generation of native Revit elements—such as structural framing, walls, and columns—directly from your Rhino geometry. By establishing a live link between Rhino and Revit, designers can iterate on complex forms while ensuring that the resulting BIM model is always up-to-date and ready for multidisciplinary coordination.

Professional Data Management

Beyond simple geometry exchange, Geometry Gym allows you to author custom property sets, quantities, and classification codes (such as Uniclass or Omniclass) directly in your Rhino model. This level of data enrichment is critical for modern BIM delivery standards. The software also includes delta analysis tools, allowing you to compare different versions of IFC files and identify specific changes, making it easier to manage revisions and ensure model integrity across large project teams.
