Cartesian by Formas is an AI-powered 3D modeling tool designed for architecture and product design. It allows users to sketch, describe, or import plans and photos to generate precise 3D models. The tool understands natural language instructions and builds models with maximum precision, requiring no prior learning curve. Users can add photos, plans, or sketches, and the tool preserves existing elements while allowing free changes to other parts.

The platform supports multiple file formats including Auto CAD DWG, Rhino 3DM, Sketch Up SKP, and BIM IFC. It creates real solids and NURBS geometry that can be exported to CAD software like Sketch Up and Rhino. Models can be edited by simply asking questions or giving instructions, maintaining exact dimensions and relationships between elements.

Key features include real solid modeling (not images), native export capabilities, and compatibility across platforms. Users retain ownership of their models while the AI handles complex geometric relationships. The tool eliminates the need for expensive desktop CAD licenses while supporting professional workflows from BIM to Rhino.
