Google Antigravity 2.0 with Gemini 3.5 Flash High produced the best fully autonomous result (4.5/5), notably implementing the dome's interior coffered ceiling pattern and using real architectural measurements. ModelRift with human-in-the-loop annotation scored 3.8/5. Cursor was fastest but weakest (1.4/5). Codex showed strong spatial reasoning but suffered from a preview-to-STL export mismatch. Key takeaways: speed doesn't predict quality, tool access wasn't the bottleneck, and human visual feedback still meaningfully improves results over fully autonomous generation for complex spatial CAD tasks. ## Full article daily.dev links to this article rather than hosting it.
