我用下面语句在CAD中标注一个尺寸，但结果是只显示五个点，根本不显示标注引出线及标注尺寸数据，问题出在哪？        
        AcGePoint3d xLine1St(3.0,13.0,0.0);
        AcGePoint3d xLine1En(15.0,13.0,0.0);
        AcGePoint3d xLine2St(3.0,20.0,0.0);
        AcGePoint3d xLine2En(15.0,20.0,0.0);
        AcGePoint3d arcPoint(8.0,19.0,0.0);
        AcDbObjectId dimStyId1;
AcDb2LineAngularDimension *pAngDimen=new                                      AcDb2LineAngularDimension                                  (xLine1St,xLine1En,xLine2St,xLine2En,arcPoint,NULL,dimStyId1);
    pBlockTableRecord->appendAcDbEntity(dimStyId1,pAngDimen);
