调用绘线命令，并把绘的线的线型改成虚线.

• 回答：

              acDocManager->sendStringToExecute(MxDraw::GetDatabase(MxDraw::GetCurOcxHandle())->GetDocument(),
                  _T("Mx_Line"),true,false,true,0,true
                  );            // 得到Mx_Line调用后，绘制的直线id.
              McDbObjectIdArray aryId;
              Mx::mcdbEntitysLastCmd(aryId);            if(aryId.isEmpty())                return;            // 得到虚线的id.
              McDbObjectId lineTypeId = MrxDbgUtils::getSymbolTableRecordId<McDbLinetypeTableRecord>(_T("DASHED"),acdbCurDwg());            // 修改绘的直线线型。
              for(int i = 0; i < aryId.length();i++)
              {                McDbObjectPointer<McDbCurve> spCurve(aryId[i],McDb::kForWrite);                if(spCurve.openStatus() != Mcad::eOk)                    continue;
                  spCurve->setLinetype(lineTypeId);
              }
