書的目的來說，我們決定從
OpenSCAD
開始，看起來有點斯巴達簡樸風的免費
軟體（
圖 11-7
），但它功能也很強大且容
易使用。

OpenSCAD 歡迎畫面
學習 OpenSCAD 不需要理解複雜的按鈕、
滑鼠操作或介面，但它的操作方法相當不
一樣：它使用了簡易的程式語言來編寫
腳本
（script）—也就是一連串指令。
OpenSCAD 可以編譯腳本並呈現該物件
的 3D 圖像，介面共有三個面板：
• 用來輸入設計案所需指令的編輯器
• 以 3D 方式來視覺化呈現物件的區域
• 用來顯示系統訊息、錯誤與建議的主
控台
在 OpenSCAD 中，滑鼠 只在 3D 檢 視視
窗中有用，能做到以下三件事：
• 按下滑鼠左鍵並移動滑鼠來旋轉物件
• 移動滑鼠，同時按著滑鼠右鍵來平移
畫面
• 使用滑鼠中央滾輪來縮小或放大
很簡單吧？
在開始之前，在最右側的視窗可以看到
三條互相垂直的直線—分別是 x、y 與 z
軸—三條線的交會點稱為
原點
（
origin
）。
您可使用這三根軸為參考基準來決定各
點的位置：
x
座標是用來量測某個點與
y
與
z
直線所構成之
yz
平面之間的距離；
y
座標是用來量測某個點與
xz
平面之間的
距離；最後，
z
座標當然就是用來量測某
個點與
xy
平面之間的距離。原點座標是
（0, 0, 0）。
H ello，World!
現在，請在左方欄位中輸入以下指令來
產生一個立方體：
cube([1]);
按下 F6 執行您的第一個腳本，應該會看
