   pnewdimrecord->setDimzin(8);//十進制小數顯示時，抑制後續零
   pnewdimrecord->setDimexe(30);//設置尺寸界線超出尺寸線距離爲400
   pnewdimrecord->setDimexo(0);//設置尺寸界線的起點偏移量爲300
   pnewdimrecord->setDimtxt(30);//設置文字高度
   pnewdimrecord->setDimtad(1);//設置文字位置-垂直爲上方，水平默認爲居中，不用設置
   pnewdimrecord->setDimgap(10);//設置文字位置-從尺寸線的偏移量
   pnewdimrecord->setDimtih(0); 
   pnewdimrecord->setDimtix(1);//設置標註文字始終繪製在尺寸界線之間

設置自動標註的精度pnewdimrecord->setDimdec(2);        //小數點後兩位

設置標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)

 

在我們建立標註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，下次再調用這個程序是，如果程序識別到已經有這個名字的存在，它就不會再對樣式表進行設置了，所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）。
