工程圖學 3D CAD

康仕仲

腦袋裡常裝著許多立體物件的形貌，想分享出來，可是不知道怎麼表達？怎麼將心中那個立體的形象，「繪製」出來呢？3D建模技術，幫助我們建構最直觀可以理解的立體模型，跳過利用平面圖解讀三維物體的過程，最能直接有效地表達我們的想法。

我們設計了許多範例，讓大家可以快速地理解3D CAD軟體 Sketchup 的使用邏輯，與繪製技巧，從入門到進階，介紹SketchUp 各項3D建模技術。完成『工程圖學3D CAD』後，把天馬行空的想法，以3D建模技術繪製出來，不再是難事！

本課程目標是建構三維模型，電腦實作為主要講授教材，以豐富有趣的範例與完整的繪製過程，步驟化地引導如何使用Sketchup這套3D建模軟體的技術。完成『工程圖學3D CAD』，你將有能力將存在於想像裡的立體物件，透過3D建模，實現出來！
