   pnewdimrecord->setDimasz(20);//设置箭头大小

   pnewdimrecord->setDimzin(8);//十进制小数显示时，抑制后续零

   pnewdimrecord->setDimexe(30);//设置尺寸界线超出尺寸线距离为400

   pnewdimrecord->setDimexo(0);//设置尺寸界线的起点偏移量为300

   pnewdimrecord->setDimtxt(30);//设置文字高度

   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

   pnewdimrecord->setDimgap(10);//设置文字位置-从尺寸线的偏移量

   pnewdimrecord->setDimtih(0); 

   pnewdimrecord->setDimtix(1);//设置标注文字始终绘制在尺寸界线之间

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(_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）。
