摘   要
 作為最常用的CAD系統，AutoCAD是世界上擁有用戶最多的CAD 軟件。由于它是通用性的軟件，用它進行各種專業設計會比較復雜，因此, AutoCAD允許用戶根據各自行業的繪圖特點、繪圖要求，把它開發成為能夠滿足本行業設計師需要的CAD系統。隨著智能建筑行業的發展，計算機輔助設計技術逐漸進入智能建筑領域，但目前還沒有適合智能建筑行業的繪圖軟件。
 本文根據智能建筑行業繪圖設計的特點，通過分析繪圖的功能和特點，抽象出不同圖元的對象類，利用AutoCAD二次開發功能開發出以圖元工具為基礎的制圖軟件。本設計是基于AutoCAD的智能建筑制圖軟件的開發，主要研究內容包括兩部分：基本繪圖工具和專業繪圖工具。由于時間所限，基本繪圖工具僅開發了圓、圓弧和多線段，專業繪圖工具僅開發了電容和開關。

 Abstract
 As the most common CAD software, AutoCAD has most users in the world wide. Because it is common software, it will be complicated for users to use it for specialized graphic design. Therefore, AutoCAD allows users develop it into the secondary development system, which is meets to the designer's need and is adapted to the graphics features and graphics requirements. With the development of intelligent building, the computer aided design is introduced into the intelligent building field. However, it has no appropriate CAD software for intelligent building at present.
 In this thesis, according to the characteristics of graphic design in intelligent building field, various graphics units were constructed by analyzing graphics functions and graphics features. Furthermore, a graphics software base on graphics units was developed using the secondary Development function of AutoCAD. In this design, an intelligent building graphics design software was developed, which is compose of two main sections, basic graphics tools and specialized graphics tools. Since time is limited, only arc, circle and polyline are developed in basic graphics tool, and only capacitor and switch are developed in specialized graphics tool.
