找不到需要的符號？告訴我們名稱就好。
用於零件清單的屬性
每個圖塊的型號標記是可見屬性（例如 O-ring 29.87 x 3.53）。不可見屬性有 SIZE_CODE、ID_MM、CS_MM、STANDARD、MATERIAL、HARDNESS_IRHD、PART_NO、MANUFACTURER、QTY 與 REMARKS。規格代號、內徑與截面已填好，材料與硬度請依你的訂購需求修改。
用 BlockSync 把組裝圖中的 O 形環匯出到 Excel，得到含規格、材料與數量的明細表，修改後可一次寫回圖面，寫回前有預覽並自動備份。
怎麼使用這個符號庫
- 解壓檔案，開啟 DWG。把需要的符號複製到你的平面圖裡，或者從設計中心（ADCENTER）把圖塊拖進來。
- 圓環依真實尺寸繪製，1 個繪圖單位 = 1 mm：內圓是內徑，外圓是內徑加兩倍截面。請以 1:1 插入。小圓環就畫得很小，目錄圖只是為了方便檢視才把它們放大。
- 插入點是圓環的中心。左邊是端視圖，右邊是剖開的截面：中心線上下各一個截面直徑的圓，所以同一個圖塊既能用在平面視圖，也能用在剖視圖。需要哪個視圖就分解圖塊，保留那一部分。
- 五個庫只在截面上不同，請依需要的截面選庫，再依規格代號或內徑查找。圖塊名稱是 ORG_ 加規格代號，例如 ORG_210。
