蓄勢待發

歡迎來到CAD/BIM專項課程的《工程圖學 3D CAD》，想了解這門課？所有資訊請看這！告訴你所有修課應知道的事，以及如何準備軟體。

範例ㄧ 神奇方塊

第一個教學範例，第一次使用SketchUp要會什麼？從最基本的繪製一條線，形成一張面，到拉出一塊體積，本模組介紹SketchUp建立立體模型最核心也最常用的推拉工具，以及如何判別鎖點，如何等分線段等等，和其他實用的輔助按鍵功能。

範例二 畫房子

「移動」工具也可以是變形、雕塑模型的好工具，在畫房子的範例中，你會學到如何從一塊長方體，以一條線，和移動工具，將長方體變成一棟斜屋頂的小房子，還有畫弧工具，以及平面交集功能，快來看看這些技巧如何搭配應用，繪製出一棟精緻的小房屋！

範例三 海灘球

怎麼畫出一顆球體？！本範例要介紹各位SketchUp建模強大的「路徑跟隨」功能，只要你有一條路徑，一張截面，你就能掃出各式各樣的弧面。以及教你如何輸入旋轉複製指令，複製出物件並呈你要的方式均勻排列。最後，是上色工具「油漆桶」，為潔白的模型，增添美麗的色彩吧！

範例四 畫窗簾

窗簾的皺褶怎麼繪製？用什麼技巧，可以將一條曲線，向第三維方向長出一張曲面？本模組介紹「比例工具」的使用，平移複製指令，鏡射的方法以及柔化平滑邊緣功能，美化窗簾表面。本範例透過畫窗簾，讓大家見識SketchUp看似平凡的工具，經過巧妙的搭配應用，也能創造出厲害的效果！

範例五 實心工具

本模組介紹的實心工具，【屬於SketchUp Pro 付費專業版才有的功能】，因此在這個模組，各位不必繳交作業。在此提供實心工具中，「相減」技巧的介紹，這是一個相當好用的建模概念與邏輯，幫助各位在建模時想出，除了直接循著物體結果的樣貌來繪製以外，還可以採取什麼不一樣的方式，讓建模簡單化！

下回見！

學了一身SketchUp 3D建模技巧，接下來，要用這些技能做什麼呢？快來看看下一門課會帶給你什麼挑戰吧！
