CAA怎样实现这个命令？

各位高手：
      现在我打开了一个CATPart文件，想把这个文件中的图形投影到这个图形中的xy面上去产生一个CATDrawing文件，请问在程序中怎么实现，用的是前视图命令，如图，就是说要用程序打开一个CATDrawing文件，图纸用默认的那种.

建立一个Empty Sheet(如图)
谢谢各位了

就是选择这一项

挺麻烦的，说说思路吧：
  
1。首先要生成一个新的Drawing, 在interactive mode的话，从session QI 得到一个CATIIniInteractiveSession， 用CATIIniInteractiveSession：：New("Drawing", opMyEditor)来生成一个新Drawing。（batch的话用CATDocumentServicesew）
  
2.从这个新Drawing的Doc QI 一个CATIDftDocumentServices，用CATIDftDocumentServices::GetDrawing()莱得到CATIDrawing, CATIDrawing QI CATIDftDrawingFormats, CATIDftDrawingFormats::GetAvailableFormats()得到可用的Format先放着，以后从这里面取一个自己想用的设置上去
  
3。从3D生成Drawing要用到CATIDftViewMakeUp。先从Container QI CATIDrwFactory， 用CATIDrwFactory：：CreateViewWithMakeUp（）生成一个CATIDftViewMakeUp。
  
4。从CATIDftViewMakeUp：：GetView（）得到一个CATIView，这是才能用CATIView：：SetDoc（）把3D的Part的linkableObject设上去，还要用CATIView：：SetViewType(FrontView)来指定前视图。
  
5。还没完，从3D生成2D视图需要指定一个投影平面，由CATIView QI 一个CATIGenerSpec，用CATIGenerSpec::SetProjPlane()设定。
  
6。最后，对Drawing的Sheet设定Format(前面得到的), 指定CATIDftViewMakeUp在Sheet中的位置(CATIDftViewMakeUp::SetPosition), 再最后，把CATIDftViewMakeUp加到Sheet上(CATISheet：：AddView)
  
7。嗯，别忘了还要Save文件。

我用了这段代码，想要在画好的圆心处标注一个Text,结果圆画出来了，可是圆心处没有标注，请问为什么？

我想实现把CATPart投影到CATDrawing里面，投到spPlane上面，结果是没有投影，我自己在CATDrawing里面画了个圆，想给圆心加批注，也没有成功，结果如图：

>>可是圆心处没有标注
可能是你画歪了，哈哈。
好了，不开玩笑，我想可能是你API调用的顺序错了。
请试试下面的code, 我胡乱调了一下，就出来了。 ：）
>>结果是没有投影
怕是你没有给正确的CATILinkableObject,
你用的是
  CATILinkableObject_var spLink=pDocument;  
  piNewView->SetDoc(spLink);  
这样得到的CATILinkableObject是不对的。
必须这样得到：
  CATFrmEditor *pCurrFrmEditor = GetEditor();
    CATPathElement oUIActPathElem = pCurrFrmEditor->GetUIActiveObject();
    CATBaseUnknown* pCurrElemBase = oUIActPathElem.CurrentElement();
    CATILinkableObject_var spLink(pCurrElemBase);
  
好了，试试我调过的code吧，在我这里是都出来了：
  
  //Have to use this way to get the right CATILinkableObject
  CATFrmEditor *pCurrFrmEditor = GetEditor();
    CATPathElement oUIActPathElem = pCurrFrmEditor->GetUIActiveObject();
    CATBaseUnknown* pCurrElemBase = oUIActPathElem.CurrentElement();
    CATILinkableObject_var spLink(pCurrElemBase);

太感谢saeba兄了，问题解决得差不多了
：）

请问在2楼弹出的对话框能否让程序去完成用户单击Ok的操作？

高手看看有什么办法
