How it works
From idea to CAD model in minutes
Describe what you need
Tell the AI agent what you want to build in plain English. Add dimensions, materials, or constraints, or let the agent figure out the details.
AI agent builds it in the cloud
The agent generates production-ready CAD geometry directly in your browser. Review the model, request changes conversationally, and collaborate with your team in real-time.
Export to your favorite software
Download your design as STEP, IGES, STL, or native formats for SolidWorks, AutoCAD, and Fusion 360. Ready for CNC, 3D printing, or further refinement.
Testimonials
Trusted by engineers worldwide
“BuildCAD AI cut our concept-to-prototype time from weeks to days. The text-to-CAD feature is genuinely useful. I describe a bracket or housing and get a solid starting point in seconds.”
“I was skeptical about AI-generated CAD, but the parametric output is surprisingly clean. It handles the tedious geometry so I can focus on the actual design decisions.”
“The design optimization alone justified the subscription. We reduced material waste by 23% on a production run by running our existing models through BuildCAD's AI analysis.”
