Generating Visuals from Floor Plans and Elevations

Answer

Short answer:

Yes, you can generate realistic images directly from floor plans and elevations. You simply upload your 2D drawing as a base image, describe the desired style or materials, and Rendair AI converts the line work into a visualized render.

Overview

Architects and designers often have technical CAD drawings long before they have fully textured 3D models. However, clients frequently struggle to understand 2D black-and-white lines.

Rendair AI bridges this gap by allowing you to use existing technical documentation as the foundation for visualization. By interpreting the structural lines of a floor plan or the geometry of an elevation, the platform applies lighting, texture, and depth. This allows you to present polished concepts using only simple 2D exports, saving the time usually required to build and texture a full 3D scene.

How it works

The process treats your drawing as a structural guide for the AI.

1. Upload the file: You upload your floor plan, section, or elevation. Supported formats include JPG, PNG, TIFF, and single-page PDF.

2. Describe the outcome: In the prompt area, you describe the materials, lighting, and style (e.g., "Modern minimalist living room, oak flooring, soft afternoon light" or "Realistic architectural elevation, brick facade, glass windows").

3. Generate: The system analyzes the lines in your uploaded image and fills the spaces with the textures and lighting described in your prompt.

4. Refine: If specific details need changing, you can use the editing tools to mask areas and regenerate just those sections.

Capabilities

Using 2D inputs allows for several specific workflows useful in early design and marketing.

• 2D to 3D translation: Turn a flat elevation drawing into a photorealistic perspective of the building facade.

• Plan texturing: Convert black-and-white CAD floor plans into colored, textured marketing plans that show flooring materials and furniture styles.

• Sketch interpretation: Upload hand-drawn sketches of elevations or layouts to generate polished concept images.

• Style iterations: quickly generate five or six different material options for a single elevation without changing the geometry.

Inputs and outputs

Inputs

• File formats: JPEG, JPG, PNG, WEBP, TIFF, HEIC, AVIF, and single-page PDF.

• File size: Maximum upload size is 10MB.

• Note on PDFs: If you have a multi-page PDF or a file that cannot be edited, converting it to a high-quality JPG before uploading is recommended.

Outputs

• Resolution: Default generations are approximately 1MP (or 2K with specific models like Nano Banana).

• Aspect Ratio: The output image will inherit the exact aspect ratio of your uploaded floor plan or elevation.

• Upscaling: You can upscale the final result to 2K, 4K, 6K, or 8K depending on your needs.

When to use this

• Real estate marketing: When you need to turn technical floor plans into attractive assets for brochures or listings.

• Client presentations: When you want to show a realistic facade option during a meeting but have not modeled the environment yet.

• Design development: When you need to decide between different material palettes (e.g., brick vs. stucco) instantly.

Limitations or notes

• Geometric accuracy: While the AI adheres to the lines provided, it is a generative tool. It may occasionally misinterpret complex CAD symbols or hatch patterns.

• Text handling: AI renders may blur or distort text labels found on plans. It is often best to upload a "clean" version of the plan without dimension lines or room labels, and add text back in post-production.

• Visual vs. Technical: These images are intended for visualization and communication, not for construction documentation.
