Geometry Gym
Geometry Gym is a family of Rhino, Grasshopper, Revit, Tekla, Navisworks, and structural-analysis add-ons focused on openBIM IFC exchange, parametric geometry, and model conversion so AEC teams spend less time rebuilding the same structure in every application.
Geometry Gym grew out of a simple pain: the same bridge or stadium roof gets modeled once in Rhino, again in Revit, and again in a solver deck, and each hop invites silent drift. The vendor positions the tools around IFC-centric workflows, Grasshopper automation, and connectors into hosts such as Revit, Tekla, Navisworks, and ARCHICAD (Geometry Gym marketing site, 2026).
Installation docs spell out practical mechanics: Rhino-side packages ship through Yak by searching gg or the free BullAnt base in Package Manager, while Revit and Navisworks builds arrive as Windows .msi installers from the downloads area with hosts closed during install (Geometry Gym technical installation guide, 2026). Licensing starts with a 30-day evaluation, then moves to a floating internet license server for commercial seats, with academic access available on request (Geometry Gym licensing page, 2026).
On the analysis side, the public overview lists SAP2000, Autodesk Robot, Strand7, ETABS, Oasys GSA, SPACE GASS, and Karamba3D among supported structural targets, plus notes about IFC2x3 export options and keeping pace with newer IFC releases (Geometry Gym marketing site, 2026). That mix matters when a computational designer wants one Grasshopper graph to drive both BIM authoring and member checks.
Commercial price tags are not published as a shopping-cart total: after the trial you request a quote, and the vendor also sells through Rhino resellers in some regions (Geometry Gym licensing page, 2026). Budget conversations should include how many concurrent seats you need and which host versions you must support.

Pros and cons
Pros
- Strong openBIM and IFC positioning with explicit host coverage
- Tight coupling to Rhino and Grasshopper for designers who already live there
- Documented trial and floating-license model for teams
Cons
- Windows-first installer story for several hosts; macOS users should validate host coverage before buying
- Commercial pricing requires a quote rather than instant checkout
- Deep workflows assume willingness to maintain disciplined Grasshopper graphs
Key features
IFC workflows: Import, export, generate, and edit IFC inside Rhino and Grasshopper with attention to newer releases while still offering IFC2x3 paths when required (Geometry Gym site, 2026).
Rhino to Revit handoff: Dedicated messaging around cleaner transfers when geometry updates, including awareness of Rhino Inside Revit as another path (Geometry Gym site, 2026).
Structural model bridges: Connectors toward SAP2000, Robot, Strand7, ETABS, Oasys GSA, SPACE GASS, and Karamba3D for building and refreshing analysis models (Geometry Gym site, 2026).
Tekla and Navisworks: Plugins to generate native Tekla geometry from Grasshopper and enhanced Navisworks importers aimed at 4D and 5D style IFC data (Geometry Gym site, 2026).
Installer and package story: Yak-based Rhino installs versus MSI installers for Revit and Navisworks with registry or manifest registration on Windows (Geometry Gym technical docs, 2026).
Licensing options: 30-day evaluation, floating commercial licenses, and academic programs described on the licensing page (Geometry Gym technical docs, 2026).

Frequently asked questions
How much does a commercial Geometry Gym license cost?
The public licensing page does not list a fixed dollar price. It explains commercial access through a floating internet license server and tells buyers to email Geometry Gym or work with Rhino resellers after completing the trial (Geometry Gym licensing page, 2026). Expect a quote that reflects modules, concurrent seats, and regions.
Is there a free trial for Geometry Gym Rhino plugins?
Yes. The licensing documentation states Rhino plugins can be evaluated free for up to 30 days and warns that the trial clock starts when you request the license, so download the packages you need first (Geometry Gym licensing page, 2026). You trigger a license request dialog from a Geometry Gym command or with
ggZZLicenseRequestin Rhino per the installation guide (Geometry Gym installation guide, 2026).Does Geometry Gym support IFC files between Revit and Rhino?
The vendor markets IFC import, export, generation, and manipulation inside Rhino and Grasshopper, plus Revit-oriented tooling such as an enhanced IFC importer for Revit (Geometry Gym site, 2026). That is the intended interoperability path rather than native
.rvtdatabase editing inside Rhino.How do I install Geometry Gym for Revit versus Rhino?
Rhino tools install through Rhino Package Manager by searching for Geometry Gym packages or BullAnt, then restarting Rhino so
ggcommands appear (Geometry Gym installation guide, 2026). Revit and Navisworks builds use downloadable MSI installers with hosts closed during setup (Geometry Gym installation guide, 2026).Can Geometry Gym send a Grasshopper model to ETABS or SAP2000?
The public applications list explicitly includes ETABS and SAP2000 among structural analysis platforms supported through Rhino and Grasshopper connectors, alongside Robot, Strand7, Oasys GSA, SPACE GASS, and Karamba3D (Geometry Gym site, 2026). Verify the solver version you run is still in the supported matrix before you freeze a project template.
Who should adopt Geometry Gym instead of only native Revit tools?
Marketing calls out architects, engineers, contractors, owners, and asset managers who juggle Rhino, Grasshopper, Revit, Tekla, Navisworks, OpenBuildings, or Archicad and want fewer manual rebuilds (Geometry Gym site, 2026). Teams that rarely touch IFC or parametric links will see less payoff than studios standardizing on those hops.
