NX二次开发：图纸模块相关函数汇总

环境：Win10, VS2017,NX1907

1.获取所有 图纸 页对象

std::vector<tag_t> GetAllSheet(){    int drawCount = 0;    tag_t* drawingTag = NULL;    UF_DRAW_ask_drawings(&drawCount, &drawingTag);     if (0 == drawCount)    {        return std::vector<tag_t>();    }        std::vector<tag_t> res;    for (int i = 0; i < drawCount; ++i)    {        res.push_back(drawingTag[i]);    }     return res;}

2. 使用 NX 对话框，选择对象 控件 ，选中某一个图纸节点时，获取的不是图纸对象，需要转化

//计算得到005-1@0，返回005-1bool CalSheetUINodeName(tag_t sheetObj, std::string &sheetName){    sheetName = "";    if (NULL_TAG == sheetObj)    {        return false;    }     bool res = false;    std::string endKeyword = "@0"; //界面上选择的图纸会有后缀名字    std::string tmpName = GetObjName(sheetObj);    if (tmpName.size() > endKeyword.size())    {        std::string endValue = tmpName.substr(tmpName.size() - endKeyword.size());        if (endValue == endKeyword)        {            res = true;            sheetName = tmpName.substr(0, tmpName.size() - endKeyword.size());        }    }     return res;}

3.判断是否图纸模块

bool IsInDafting(){    int module = UF_APP_NONE;    UF_ask_application_module(&module);     return (module == UF_APP_DRAFTING);}

4.进入图纸模块

void UDS::SwitchDraw(){    NXOpen::Session::GetSession()->ApplicationSwitchImmediate("UG_APP_DRAFTING");}

5. 打开图纸页

bool OpenSheet(tag_t sheet){    if (NULL_TAG == sheet)    {        return false;    }     NXOpen::Session *theSession = NXOpen::Session::GetSession();    NXOpen::Part *workPart(theSession->Parts()->Work());    NXOpen::Part *displayPart(theSession->Parts()->Display());     NXOpen::Drawings::DraftingDrawingSheet *draftingDrawingSheet1 = (dynamic_cast<NXOpen::Drawings::DraftingDrawingSheet *>(ToNXObj(sheet)));    if (NULL == draftingDrawingSheet1)    {        return false;    }     draftingDrawingSheet1->Open();     //更新视图    workPart->Views()->WorkView()->UpdateCustomSymbols();     workPart->Drafting()->SetTemplateInstantiationIsComplete(true);     return true;}

6 图纸页 导出图片

//窗口区域导出图片//文件-导出-图像-(图形区域，png）bool ExportImage(std::string exportPicPath){    NXOpen::Session *theSession = NXOpen::Session::GetSession();    NXOpen::Part *workPart(theSession->Parts()->Work());    NXOpen::Part *displayPart(theSession->Parts()->Display());     NXOpen::Gateway::ImageExportBuilder *imageExportBuilder1 = NXOpen::UI::GetUI()->CreateImageExportBuilder();    imageExportBuilder1->SetRegionMode(false);     std::vector<int> regiontopleftpoint1(2);    const int regiontopleftpoint1_initial_values[] = { 0, 0 };    regiontopleftpoint1.assign(regiontopleftpoint1_initial_values, regiontopleftpoint1_initial_values + 2);    imageExportBuilder1->SetRegionTopLeftPoint(regiontopleftpoint1);     imageExportBuilder1->SetRegionWidth(1);     imageExportBuilder1->SetRegionHeight(1);     imageExportBuilder1->SetFileFormat(NXOpen::Gateway::ImageExportBuilder::FileFormatsPng);     imageExportBuilder1->SetFileName(exportPicPath);     imageExportBuilder1->SetBackgroundOption(NXOpen::Gateway::ImageExportBuilder::BackgroundOptionsOriginal);     imageExportBuilder1->SetEnhanceEdges(false);     bool res = false;     try    {        NXOpen::NXObject *nXObject1 = imageExportBuilder1->Commit();        res = true;    }    catch (...)    {     }     imageExportBuilder1->Destroy();    return res;}
