Questions & Answers
Which Rhino versions are supported?
Planaria works with Rhino 7 and Rhino 8 on Windows. Mac support is planned for a future release.
Do I need programming knowledge to use this?
No programming knowledge required. Just describe what you need in plain language. Planaria handles the component generation.
How does auto-fix work?
If your generated component has errors, Planaria automatically analyzes and fixes them. You get up to 3 retry attempts for free.
Can I edit the generated components?
Yes! Generated components are fully editable. Double-click to view and modify anytime.
Is my data secure?
Your prompts are processed securely. We don't store your geometry data or share it with third parties.
