{ 
   AcCmColor color1,color2,color3;
   color1.setColorIndex(1);
   color2.setColorIndex(2);
   color3.setColorIndex(3);
   AcDbAlignedDimension* p = new AcDbAlignedDimension();
   p->setXLine1Point(AcGePoint3d(0,0,0));

   p->setDimensionText(_T("TEST"));
   p->setDimclrt(color1);
   p->setDimclre(color2);
   p->setDimclrd(color3);
   CAddEntity().AddEntity(p);
   p->close();
