   pnewdimrecord->setDimzin(8);//十進制小數顯示時，抑制後續零

   pnewdimrecord->setDimexe(30);//設定尺寸界線超出尺寸線距離為400

   pnewdimrecord->setDimexo(0);//設定尺寸界線的起點偏移量為300

   pnewdimrecord->setDimtxt(30);//設定文字高度

   pnewdimrecord->setDimtad(1);//設定文字位置-垂直為上方，水準預設為居中，不用設定

   pnewdimrecord->setDimgap(10);//設定文字位置-從尺寸線的偏移量

設定自動标注的精度pnewdimrecord->setDimdec(2);        //小數點後兩位

設定标出的值是圖形實際尺寸的一半，而不是尺寸的實際值

AcDbRotatedDimension *pdim;pdim->setDimlfac(0.5)

在我們建立标注樣式或文字樣式時都習慣把他們設一個名字，如setName(_T("仿宋"))

但是取了名字之後有一個問題就是，下次再調用這個程式是，如果程式識别到已經有這個名字的存在，它就不會再對樣式表進行設定了，是以我們很多時候調用了一次，下次調用發現根本就沒起作用就是這個道理。（當然這也是我自己的判斷）。
