也就是说，我传递机制没做成功。我要是把    _pWiperAgent -> AddOrderedElementType("CATCurve"); 这句话换成_pWiperAgent -> AddOrderedElementType("CATSurface");  来选择面，则两个都能选取。

void AreaCheckCmd::BuildGraph()
{
_pAxisAgent = new CATFeatureImportAgent ( "CurveAgent", NULL, NULL, MfNoDuplicateFeature ) ;
_pWiperAgent = new CATFeatureImportAgent ( "CurveAgent", NULL, NULL, MfNoDuplicateFeature ) ;
_pOKAgent = new CATDialogAgent( "OKButton") ;
_pOKAgent-> AcceptOnNotify( pAreaCheckDlg , pAreaCheckDlg->GetDiaOKNotification() );

//代理只能够选择实现接口CATSurface和CATPoint,CATCurve的组件，即此代理只能够选择面和曲线
_pAxisAgent -> AddOrderedElementType( "CATCurve" );
_pWiperAgent -> AddOrderedElementType("CATCurve");//一维的：CATIMfMonoDimResult
_pAxisAgent -> SetBehavior( CATDlgEngWithPrevaluation | CATDlgEngWithCSO  | CATDlgEngOneShot  );
_pWiperAgent -> SetBehavior( CATDlgEngWithPrevaluation | CATDlgEngWithCSO  | CATDlgEngOneShot  );

//-----------------------------------------------------------------------------
// Command States
//-----------------------------------------------------------------------------
CATDialogState *WaitForAxisState= GetInitialState("选择基准轴线");
WaitForAxisState -> AddDialogAgent( _pAxisAgent);

CATDialogState *WaitForWiperState= GetInitialState("选择与轴线相对应的线条");
WaitForWiperState -> AddDialogAgent( _pWiperAgent);

CATDialogState *OKState= GetInitialState("确定");
OKState -> AddDialogAgent( _pOKAgent);
//-----------------------------------------------------------------------------
// Transitions
//-----------------------------------------------------------------------------
// 选择线
AddTransition ( WaitForAxisState , WaitForWiperState ,
IsOutputSetCondition ( _pAxisAgent ) ,
Action ( ( ActionMethod ) &AreaCheckCmd::AxisSelected ) );
//选择线
AddTransition ( WaitForWiperState , OKState ,
IsOutputSetCondition ( _pWiperAgent ) ,
Action ( ( ActionMethod ) &AreaCheckCmd::WiperSelected ) );
//传递到OK按钮
AddTransition ( OKState , NULL ,
IsOutputSetCondition ( _pOKAgent ) ,
Action ( ( ActionMethod ) &AreaCheckCmd::OkAction ) );

AddAnalyseNotificationCB (pAreaCheckDlg,
pAreaCheckDlg->GetDiaCANCELNotification(),//这里标明作用部分  为取消按钮
(CATCommandMethod)&AreaCheckCmd::CancelAction,
NULL);
AddAnalyseNotificationCB (pAreaCheckDlg,
pAreaCheckDlg->GetWindCloseNotification(),//这里标明作用部分  为关闭按钮  也就是右上角的叉
(CATCommandMethod)&AreaCheckCmd::CancelAction,
NULL);

}

修改搞定：
//-----------------------------------------------------------------------------
// Command States
//-----------------------------------------------------------------------------
CATDialogState *WaitForAxisState= GetInitialState("选择基准轴线");
WaitForAxisState -> AddDialogAgent( _pAxisAgent);

CATDialogState *WaitForWiperState= AddDialogState("选择与轴线相对应的线条");
WaitForWiperState -> AddDialogAgent( _pWiperAgent);

CATDialogState *OKState= AddDialogState("确定");
OKState -> AddDialogAgent( _pOKAgent);

这样一来遇到新问题就是，一旦在选择的过程中，选错线条了，就没法修改了！很是郁闷！

因为你一直在GetInitialState，如果有添加其他的状态，用AddDialogState

没法修改是因为你的状态没有切换，你可以试着多添加几个状态，或者添加Editor的Focus
