Open assembly with specific design view representation in C++

By Xiaodong Liang

If you want to open in a specific design view, you need to use OpenWithOptions, while Open method can only open the assembly with LOD (Level of Detail) option.

Following is a code to open an assembly with last active LOD and last active design view

static HRESULT GetInventorInformation()

{

    HRESULT Result = NOERROR;

 

   // Assume Inventor application pInvApp is available

    CComPtr<Documents> pAllDocs = NULL;

    Result = pInvApp->get_Documents(&pAllDocs);

 

    CComPtr<FileManager> pFileManager;

    Result = pInvApp->get_FileManager(&pFileManager);

 

    _bstr_t bsCurrentDocumentName(L"C:\\test.iam"); 

 

    // get last LOD

    BSTR strLastActiveLOD;

    Result =

        pFileManager->

        GetLastActiveLevelOfDetailRepresentation(bsCurrentDocumentName,       

        &strLastActiveLOD);    

 

    // get last Design View Representation

      BSTR strLastActiveView;

    Result =

        pFileManager->

        GetLastActiveDesignViewRepresentation(bsCurrentDocumentName,

        &strLastActiveView);   

 

     BSTR strFullDocumentName;

    Result =

        pFileManager->

        GetFullDocumentName(bsCurrentDocumentName, strLastActiveLOD,

        &strFullDocumentName);

 

     CComPtr<NameValueMap> nameValueMap = NULL;

     pInvApp->TransientObjects->CreateNameValueMap(&nameValueMap);

 

    nameValueMap->

        Add(_bstr_t("LevelOfDetailRepresentation"),

        _variant_t( strLastActiveLOD) );

    nameValueMap->

        Add(_bstr_t("DesignViewRepresentation"),

        _variant_t( strLastActiveView ));

 

 

    CComPtr<Document> pDocument = NULL;

    //pDocument = pAllDocs->MethodOpen(strFullDocumentName,VARIANT_TRUE);

    pDocument =

        pAllDocs->

        MethodOpenWithOptions(bsCurrentDocumentName,nameValueMap,

        _variant_t(VARIANT_TRUE));

 

    return Result;

}
