<h2>
動手畫</h2>
<ul>
<li>先下載並安裝 <a href="http://www.sketchup.com/zh-TW/download" target="_blank">SketchUp</a>。</li>
<ul>
<li>有 Windows, Mac 版本。</li>
<li>Linux 安裝方式可以<a href="https://www.google.com.tw/search?q=sketchup+linux&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:zh-TW:unofficial&client=firefox-aurora&channel=sb&gfe_rd=cr&ei=YE1LU67uCqSOiAe6joDICg" target="_blank">搜尋</a>得到。</li>
<li>Mac 版本下載下來得到的是多國語言版本。</li>
</ul>
<li>剛開始練習畫的時候，參考點使用原點（三個軸的交叉點）。</li>
<li>開啟左側工具欄：View --> Tool Palettes --> Large tool set （老師推薦，真的很好用）</li>
<ul>
<li>（老師請我們不要叫他老師 XD 但還是想稱呼一下 :p）</li>
</ul>
<li>用四條線組成一個正方形。</li>
<ul>
<li>比較容易控制矩形的方向。</li>
<li>點一下決定起始點，移動滑鼠決定方向（例如沿著某個軸方向），輸入數值（眼睛看右下角），Enter。</li>
<li>重複四次可以圍成一個矩形。</li>
</ul>
<li>如果使用矩形工具，也可以用鍵盤輸入數值，中間用逗號隔開。例如「100,100」。</li>
<li>所有的「曲面」都是由很多很小的三角形組成的。</li>
<li>所有的「圓形」都是由多邊形組成的。</li>
<ul>
<li>所以上下兩個圓形的面如果要上下對齊形成柱狀物或其他連結，要注意參考點的方向。</li>
</ul>
<li>移動：選一個物體（和面），選一個點，選方向，輸入數值。</li>
<li>建立兩條線在矩形（或多邊形）的角落，使用弧線功能（2 point arc），方便定位並建立弧線。</li>
</ul>
