## AI 摘要

Formas 推出 AI 3D 建模工具 Cartesian，定位建筑设计领域，支持通过文字、草图或照片生成可编辑 3D 模型。模型由精确的实体和 NURBS 几何构成而非网格近似，每个对象独立可改，保留部分不被重绘，并支持导出 Rhino 3DM 和 SketchUp SKP，AutoCAD DWG 与 BIM IFC 在计划中。

## 正文

Anything to 3D.

Cartesian by Formas is an AI 3D modeling tool for architecture and product design.

Explore the model studies · Read the guides

Say it. Sketch it. Drag it in. It understands what you mean and builds it with maximum precision. Nothing to learn.

01 · Editability

Every part. Yours to edit.

Change a chair. Keep the room. Each object has its own place in the model.

02 · Precision

Geometry. With definition.

Faces, edges and solids you can inspect, measure and change.

03 · Topology

Exact solids. Clean topology.

Native surfaces, precise edges and editable assemblies. No polygon-mesh approximations.

04 · BIM

Meaning travels with geometry.

Named elements and explicit relationships give the model a structured path into BIM workflows.

How

three 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 · Photograph

02 · A rough plan

Booths 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.

Across platforms. Across file formats.

Model and edit with precision.

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.

Anything to 3D.
