没找到要用的符号？告诉我们名称就行。
用于零件清单的属性
每个图块的型号标记是可见属性（例如 O-ring 29.87 x 3.53）。不可见属性有 SIZE_CODE、ID_MM、CS_MM、STANDARD、MATERIAL、HARDNESS_IRHD、PART_NO、MANUFACTURER、QTY 和 REMARKS。规格代号、内径和截面已经填好，材料和硬度请按你的订货要求修改。
用 BlockSync 把装配图中的 O 形圈导出到 Excel，得到带规格、材料和数量的明细表，修改后可一次写回图纸，写回前有预览，并自动备份。
怎么使用这个符号库
- 解压文件，打开 DWG。把需要的符号复制到你的平面图里，或者从设计中心（ADCENTER）把块拖进来。
- 圆环按真实尺寸绘制，1 个图形单位 = 1 mm：内圆是内径，外圆是内径加两倍截面。请按 1:1 插入。小圆环就画得很小，目录图只是为了方便查看才把它们放大。
- 插入点是圆环的中心。左边是端视图，右边是剖开的截面：中心线上下各一个截面直径的圆，所以同一个图块既能用在平面视图，也能用在剖视图。需要哪个视图就分解图块，保留那一部分。
- 五个库只在截面上不同，请按需要的截面选库，再按规格代号或内径查找。图块名是 ORG_ 加规格代号，例如 ORG_210。
