🏗️ CAD Zone — 3D Models & Architectural Visualization
Generate full 3D models as downloadable files, or create concept images for buildings, interiors, and floor plans — all from a plain-English description. Requires your own Cloudflare API key (see above).
Describe any object or assembly — vehicles, furniture, mechanical parts, buildings — and the AI generates a full 3D model using Blender, including correct real-world scale, multi-part assemblies, and an optional photorealistic render. Upload an existing STL/STEP file to edit it in place. Download as STL or STEP.
Describe a building, villa, interior, or site layout and get an AI-generated concept image — exteriors, interior rooms, or top-down floor plans. Use smart prompt chips to enrich your description. Upload a reference image or DXF floor plan to guide the AI. Export results as a CAD Brief (text report) or DXF floor plan file compatible with AutoCAD, ArchiCAD, and FreeCAD.
Example: villa exterior with garden & parking
Example: living room interior with custom colors & materials
