5.    pnewdimrecord->setDimasz(20);//设置箭头大小
6.    pnewdimrecord->setDimzin(8);//十进制小数显示时，抑制后续零
7.    pnewdimrecord->setDimexe(30);//设置尺寸界线超出尺寸线距离为400
8.    pnewdimrecord->setDimexo(0);//设置尺寸界线的起点偏移量为300
9.    pnewdimrecord->setDimtxt(30);//设置文字高度
10.    pnewdimrecord->setDimtad(1);//设置文字位置-垂直为上方，水平默认为居中，不用设置
11.    pnewdimrecord->setDimgap(10);//设置文字位置-从尺寸线的偏移量
12.    pnewdimrecord->setDimtih(0); 
13.    pnewdimrecord->setDimtix(1);//设置标注文字始终绘制在尺寸界线之间
14.    pnewdimrecord->setDimtofl(1);//即使箭头放置于测量点之外，尺寸线也将绘制在测量点之间

设置自动标注的精度pnewdimrecord->setDimdec(2);        //小数点后两位

设置标出的值是图形实际尺寸的一半，而不是尺寸的实际值

AcDbRotatedDimension *pdim;pdim->setDimlfac(0.5)



在我们建立标注样式或文字样式时都习惯把他们设一个名字，如setName(采用T("仿宋"))

但是取了名字之后有一个问题就是，下次再调用这个程序是，如果程序识别到已经有这个名字的存在，它就不会再对样式表进行设置了，所以我们很多时候调用了一次，下次调用发现根本就没起作用就是这个道理。（当然这也是我自己的判断）
