China Standard Architectural CAD Generator

Problem

Early residential design often needs quick floor plans that follow Chinese drawing conventions, but manual CAD or generic drawing tools may miss GB requirements such as ceiling height, clear height, door width, paper size, line weights, and title blocks. architectual-engineer targets this workflow: it turns room areas, building type, and paper parameters into a scheme-level architectural plan instead of a structural construction drawing.

How It Works

The skill structures design input and generates drawings according to standards. Key steps include parsing building_type, total_area, and rooms; checking parameters against GB 55038-2025, GB 50016-2014, GB 50763-2012, and related codes; generating layout data; drawing walls, doors, axes, and dimensions with makerjs; adding GB/T 50001-2017-compliant sheets and title blocks; and exporting SVG and PDF.

The output is intended for scheme communication: millimeter dimensions, A0~A4 sizes, required line types, and layer names such as A-WALL, A-AXIS, and A-DIMS. Drawing data is stored as JSON for downstream edits.

Scope and Limits

It is suitable for residential scheme plans, component details, standard title blocks, and annotation generation. It is not a substitute for structural drawings based on PKPM/YJK calculations or MEP system drawings. The generated plan should still be reviewed by the architect against project-specific conditions and cannot be used directly for construction.
