  1. 中二級 等角投影法 Isometric Projection 設計與科技 --- 圖象傳意 Design and Technology --- Graphic Communication

  2. 1 3 2 4 圓形物體的繪畫 --- 四圓心方法 *主要是利用圓規畫出看似橢圓的圓形 步驟1： 畫出圓形物體的正投影圖

  3. 步驟2： 用作圖線畫出等角立體圖

  4. 步驟3： 由“大角”連線往“中心線”

  5. 對角線 步驟4： 畫出“細角”的“對角線”

  6. 步驟5： 畫出“1/4”的橢圓 半徑 圓心

  7. 步驟6： 再畫出“第二次”的“1/4”的橢圓 圓心 半徑

  8. 步驟7： 再畫出“第三次”的“1/4”的橢圓 半徑 圓心

  9. 步驟8： 再畫出“第四次”的“1/4”的橢圓 圓心

  10. 步驟9：再畫出圓形物體的“背面”(將中心點向後移動) ，完成後與前面相連 半徑 移動後的中心點
