Cartesianby Formas Cartesian by Formas is an AI 3D modeling tool for architecture and product design. [Explore the model studies](https://www.formas.ai/cartesian/examples) · [Read the guides](https://www.formas.ai/cartesian/guides) Say it. Sketch it. Drag it in. It understands what you mean and builds it with maximum precision. Nothing to learn. Yours to With Faces, edges and solids you can inspect, measure and change. Clean Native surfaces, precise edges and editable assemblies. No polygon-mesh approximations. with geometry. Named elements and explicit relationships give the model a structured path into BIM workflows. Howthree moves, every time A skylit restaurant like this one. Keep the booths along the wall exactly. Say it. Like you would to a colleague. Keep the booths 01 · Photograph02 · A rough planBooths kept exactly Add what you have. A photo. A plan. A sketch, scan or model. What you keep stays exactly. The rest is free to change. It's made. The restaurant, every chair, table and plant an exact part. Open it in SketchUp, Rhino or any CAD. Change anything by asking. What you can makereal models, made by Cartesian Across platforms. Across file formats. Bring your workflow with you—from BIM and AutoCAD to Rhino and SketchUp. Create exact solids and NURBS geometry in Cartesian, without a separate expensive desktop CAD licence. Why Real solids, not pictures. Measure it, cut it, print it, machine it. Yours stays yours. What you keep is never redrawn. What clashes is said out loud. It understands. What you mean, how things relate, what must not move.
