My 3D Floor Plan Went Viral, So I Built 7 More (Free Prompts)

Seven ways to turn a flat drawing into 3D as you scroll, all built with Opus 5.5. An exploded axo, two sections, a construction sheet, a builder's schedule, a card model and an elevation. Each one starts flat and turns into the real house when you scroll. Everything is free: the live demos, the starter prompts and the code.

No images and no 3D models, every demo is under 200 KB of code In this video I go through each technique: what it does, my demo, then what its starter prompt builds in a fresh session that knows nothing about my project, first try with no editing. Then I take the floor plan that went viral and walk you through how I polished the interior: why I removed every photo texture, how I work room by room, and which model I use for what. 👍 Leave a like if this was useful 💬 Tell me which of the 7 you liked most 🔔 Subscribe for more AI design tools, workflows, and UI experiments ➡ Follow me 👋🏽 – https://x.com/SammmAing –   / samnang-aing-639168341   – https://www.threads.com/@prompting_lab/ –   / samnang.aing   –   / samnang_aing
