by daobataotieCAD Model Control Protocol Server: Automating CAD with Natural Language
Overview
The CAD Model Control Protocol (CAD-MCP) Server is an innovative tool that bridges the gap between natural language processing and CAD automation. It enables users to control CAD software for drawing operations through simple text commands, eliminating the need for manual interface interactions. This project supports popular CAD software like AutoCAD, GstarCAD, and ZWCAD, making it a versatile solution for CAD automation.
Key Features
CAD Control Functions
- Multi-CAD Support: Compatible with AutoCAD, GstarCAD, and ZWCAD.
- Drawing Operations:
- Line, circle, arc, rectangle, and polyline drawing.
- Text addition, pattern filling, and dimension annotation.
- Layer Management: Create and switch layers effortlessly.
- Drawing Save: Save drawings as DWG files.
Natural Language Processing
- Command Parsing: Converts natural language instructions into CAD operation parameters.
- Color Recognition: Extracts and applies color information from text.
- Shape & Action Mapping: Recognizes various shape descriptions and drawing actions.
