開始學習工程圖學2D CAD需要什麼準備？所有的課程資訊看這裡！第一個模組的內容包括：工程圖學涵蓋什麼主題？作業如何評分？如何通過這門課？當然，你一定需要安裝AutoCAD 2015這套軟體。你也可以在以下的連結找到軟體安裝的方法。

工程圖學的意義與知識 Significance and Knowledge of Engineering Graphics

所有的學習與知識建構都立基於基本原理與實作相關的先備知識。這個模組將帶你初步了解工程圖的產出過程，從發現問題，形成想法，畫製草繪圖、設計圖，到產出完稿圖。同時你也將認識如何讀圖、製圖、表達與敘述圖表…等工程師必備的圖學能力與素養與今日工程圖學的常用繪圖工具與使用時機。*本模組提供1個不計分的測驗練習。

基礎圖形繪製

「工欲善其事，必先利其器」。這個模組將由介紹平面草繪的基礎技巧開始，包含畫直線、圓、橢圓與弧的方式，並闡述如何生活中實作應用這些繪圖技巧。同時也開始AutoCAD電腦繪圖教學，讓你輕鬆上手，學會基本圖形工具的使用！*本模組包含第一次計分測驗，提供3個不計分練習。

幾何圖法

工程製圖表現物體的形貌，本是由各式各樣的幾何圖形組成，這個模組要教你的是幾何構圖的方法與原理，你也會因擁有正確的幾何知識，知道如何繪製多邊形、橢圓與拋物線等較難以直接精準描繪的圖形！\本模組包含第二次計分測驗。/

三視圖

本模組將更深入探討「投影」的原理與特性，你將更加了解二維平面圖與三維立體物之間的關係，訓練從平面想像出立體的讀圖能力；並學會三種常見的立體圖，分等角圖、斜投影圖，以及透視投影圖，的繪製原理及其適用時機。\ *本模組包含第四次計分測驗，以及第三次計分互評作業。\

立體圖

本模組將更深入探討「投影」的原理與特性，你將更加了解二維平面圖與三維立體物之間的關係，訓練從平面想像出立體的讀圖能力；並介紹三種常見的立體圖，分等角圖、斜投影圖，以及透視投影圖，的繪製原理及其適用時機。\ 本模組包含第四次計分測驗，以及第三次計分互評作業。\
