Turn text or images into 3D models in seconds
Type a description and receive a 3D model in roughly 10 seconds, with style customization for simpler control.
Upload a single image or multiple views to reconstruct geometry with higher accuracy; multi-view input improves precision noticeably.
Generate professional-grade PBR textures with detailed surface structure, seamless tiling, and intelligent style transfer.
Export as GLB/GLTF, FBX, OBJ/MTL, or STL so assets drop into game engines, 3D printing, AR/VR, and design tools.
Generative AI that turns text and images into CAD models
Generate feature-based, parametric CAD parts from text descriptions, PDFs, DXFs, and PNG/JPG images in native and neutral formats.
Create top-down or bottom-up assemblies from text, with components and mating constraints generated automatically.
Agents for design specs, CAD generation, multi-physics simulation via Ansys/Altair, and design optimization.
Train and serve proprietary models on your engineering data with LoRA fine-tuning and multi-cloud, private, or managed deployment.
