RADii Viewer
By Thomas Lee
RADii Viewer is an AR/VR visualization app for Rhino3D/Grasshopper3D users on iOS and Android.
The App DNA
What makes this app unique?
It removes the friction of transferring complex 3D architectural models from desktop design environments to field-based AR/VR review sessions.
For Architects, designers, and students using Rhino3D/Grasshopper3D who require real-time 3D model collaboration and AR/VR visualization.
What does it look like?
Key features
Streams 3D content from Rhino3D/Grasshopper3D plugins directly to mobile or VR headsets.
Integrated communication tool for domain members, exclusive to the Collective tier.
Allows Personal and Collective users to host publishing servers locally for data sovereignty.
How much does it cost?
Subscription model segments users by storage, member count, and commercial use rights, with a free tier serving as a lead-generation tool for the plugin.
Velocity
Maintenance developmentUX improvementsShow more...
RADii Viewer maintains a maintenance cadence, having shipped only one release in the observed window. Development activity is currently limited, with the latest version focusing on minor functional adjustments rather than significant feature expansion. The current release frequency of approximately one update every three months suggests a stable but slow development cycle. Future updates are expected to continue at this infrequent pace.

Key takeaways for RADii Viewer
Where is it heading?
The market for architectural AR/VR visualization is shifting toward standalone, cloud-native tools that remove the dependency on desktop-based plugins. RADii Viewer remains advantaged by its deep integration with Rhino3D, but the current maintenance-mode cadence leaves it exposed to rivals that iterate on a faster cycle.
- The latest release added object attributes, confirming that development continues but remains focused on incremental data functionality rather than broad feature expansion.
- A maintenance-mode release cadence limits the ability to respond to emerging AR/VR visualization competitors, which could erode the platform's utility over time.
The SWOT
- System-level integration with Rhino3D/Grasshopper3D creates a high switching cost for professional design firms.
- Localized pricing or student-to-professional conversion paths remain untapped in the Education tier.

The counter-intuitive read
The lack of public store ratings is a feature, not a bug…
Read the full takeBottom line
RADii Viewer maintains a specialized position as a Rhino3D companion, but the current maintenance-mode cadence risks losing ground to more iterative AR/VR visualization tools. A public-facing roadmap would address the uncertainty created by the limited update frequency and help secure long-term enterprise commitment.
