several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured2

如何插入工字型等异形柱子？
请用闭合pline绘制轮廓，然后使用“标准柱”命令对话框中“选择Pline创建异形柱”图标创建异形柱，这样的柱子也可以通过构件库插入预定义的异形柱。
在使用填充功能(BHATCH)时所遇到的问题。
1. 在有尺寸标注和其他符号标注的对象周围填充后，如果尺寸和符号标注有拖动和修改后，会出现标注文字周围有填充的情况。
2. 填充图案多的图形打开和修改都非常慢。
解决方法：
填充功能的关联属性将对系统的性能有极大的影响，使用这项功能时，建议清除这个设置，否则系统的速度可能将显著的降低，不同平台有不同设置界
