Sculpt3D is a native, touch-first solid modeler for Mac, iPad, iPhone, Windows and Android, built on the OpenCascade B-rep kernel. Every step stays editable in a parametric history, and an MCP server lets AI assistants model live in your open document.

30-second start

- Select edges and press F to fillet. Open History (⌥⌘P) to change any step later.
- To model with AI:
claude mcp add --transport http sculpt3d http://127.0.0.1:7317/mcp, then ask Claude to build something.
About the images
Images in images/mcp/ were rendered by the Sculpt3D viewport through its own screenshot tool, right after calling each tool with the example arguments shown in the reference. Images in images/app/ are screenshots of the app's interface (iPad, iPhone and Android tablet; the Mac app uses the same layout and rail).
