china-patent-figure-skill

This agent skill turns a STEP assembly into patent specification figures that meet Chinese patent office formatting rules. It imports the STEP file, computes hidden-line drawings from the real geometry with a geometry kernel, splits the assembly into candidate figures, assigns reference numbers automatically, draws leader lines, and runs 13 quality checks before export.

Layout follows the Chinese patent office format rules: A4 sheets, set margins, the figure number centered below each figure, characters no smaller than 3.5 mm, and only reference numbers inside the figure. The quality gates check number overlap, leader-line crossings and placement, character height, page coverage, and figure count, and a figure that fails a gate is not exported.

The export package holds a filing PDF, a disclosure Word document with a number-to-part-name table, DXF source files for further CAD editing, a figure description text, and a checklist of gate results and items for human confirmation. It runs as a skill, an MCP server, or a command-line tool, and all drawing work runs locally on the user's machine.
