Rendair tutorial: sketch, 3D and elevation to render by David Parra

David Parra makes videos about AI tools for architects and interior designers, and this is a step-by-step tour of Rendair's create and edit tools. He renders a hand sketch of a house in a forest, a Rhino interior and a technical elevation, then moves to editing, where he spends the most time. The highlight is taking a Google Maps street view in Barcelona and placing a Gaudí-inspired facade next to the Sagrada Família. It is a good watch if you want to understand what the image strength and creativity settings actually do.

What you'll see

1. Sketch to Render on a freehand sketch, asking for a brutalist house in a forest at sunset and generating four options.
2. 3D Model to Render from a Rhino interior screenshot in a Japandi style, with lower image fidelity and high creativity.
3. Image to Render on that result, turning it into a colorful, mosaic-rich room by lowering color intensity and keeping shape intensity high.
4. Render Variation to push the same image toward an architectural illustration.
5. Elevation to Render on a London rear elevation, with high fidelity so windows and lines stay put.
6. Select and Modify with a polygonal lasso to add a concrete extension to the house.
7. Remove Objects with a brush to clear an odd element from the scene.
8. The insert tool of that version: a Gaudí elevation sketch, background removed, placed onto a Google Maps facade and rendered in context.
9. Upscale at 4x, then Image to Video of a woman walking toward a window.

Takeaways

• He explains that higher creativity drifts further from the prompt and the input, so he lowers it when he needs accuracy.
• He keeps shape intensity high and color intensity low when he wants a new palette on the same geometry.
• He found the polygonal lasso the most precise selection tool he had seen in an AI app.
• He noticed a small glitch in the walking figure's leg in the video, though he still found it usable for short clips.
• He notes the tool is not free, but considers it fairly priced for what it does.

Try it yourself

Use Sketch to Render or Elevation to Render for your starting drawings, then Select and Modify to add or change parts of a building. Upscale is the last step before sharing.
