Formas opened the waitlist for Cartesian, an AI 3D modeling tool aimed at architecture and product design.

Key points:

• Accepts photos, sketches, plans, or scans and builds models via natural-language dialogue
• Highlighted editability: keep specified objects exactly (e.g. "keep the booths") while regenerating the rest
• Produces clean topology with precise faces, edges and solids instead of polygon-mesh approximations, exportable to SketchUp, Rhino and other CAD tools
• Named elements and explicit relationships feed into BIM workflows

The site showcases downloadable 3DM/STL examples across interiors, furniture, products, and architecture.
