✨ Three Ways to Create 3D

🏗️ CAD Files	🖼️ Images	💬 Text Prompts
Upload DWG or DXF	Upload any image	Describe what you want
Auto-detect layers	AI-powered reconstruction	Stable Diffusion + TripoSR
Extrude to 3D	TripoSR AI model	Generate from imagination

🎯 What Makes CADLift Special

🏗️ DWG/DXF to 3D

• DWG Support – Native AutoCAD files via ODA File Converter
• DXF Support – All versions, all layers
• Smart Detection – Auto-detects closed shapes, walls, doors, windows
• co2tools Integration – Robust extrusion engine

🖼️ Image to 3D

• Any Image – Photos, sketches, renders, screenshots
• TripoSR AI – State-of-the-art single-image 3D reconstruction
• Background Removal – Automatic subject isolation

💬 Prompt to 3D

• Natural Language – Just describe what you want
• Stable Diffusion – AI-generated reference images
• End-to-End – From text to viewable 3D model

📦 Multi-Format Export

Format	Use Case
GLB	Web 3D, game engines (Unity, Unreal, Three.js)
STL	3D printing (Cura, PrusaSlicer)
DXF	CAD software (AutoCAD, FreeCAD)
STEP	Engineering CAD (SolidWorks, Fusion 360)

🎨 Built-in 3D Viewer

• Instant Preview – View models in browser before download
• Interactive – Rotate, zoom, pan
• Online3DViewer – Industry-standard GLB support

⚡ Real-Time Progress

• Live Updates – Watch conversion progress in real-time
• Status Tracking – Detailed stage-by-stage feedback
