shell_object

MCP tool from Freecad Ai by ghbalf

Hollow out a solid (PartDesign::Thickness)

How to use it

shell_object is exposed by the Freecad Ai MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), and the shell_object tool becomes available to the model automatically. See the full listing for setup details and every tool this server provides.
