版本NX9+VS2012
NX对象属性(Attribute)是NX中的一个重要概念，是用户附加到NX对象上的字符串、
整形数值、实型数字的字段，用于对NX对象的解析或说明，广泛应用于实际的设计制造过程中。
NXOpen API通过基类NXObject来实现所有NX对象的Attribute操作。NXAttribute按照属性值类型
可以分为Integer,Real,String,Null,Time,Regerence六类，对应的NXOpen API枚举变量定义为。
通过NXObject对象，开发人员可以实现以下Attribute相关操作。
-设置NX对象属性
-遍历NX对象上某个类型的所有属性
-删除NX对象上某个类型名字的属性
-删除NX对象上某个类型的所有属性
-通过指定属性名称获得NX对象上的属性值
- 设置属性值
NXObject类通过成员函数重载的方式实现对NX对象属性的设置，这些成员函数的定义方式如下：
NX9+VS2012 #include <uf_defs.h> #include <NXOpen/NXException.hxx> #include <NXOpen/Session.hxx> #include <NXOpen/AttributeManager.hxx> #include <NXOpen/AttributePropertiesBaseBuilder.hxx> #include <NXOpen/AttributePropertiesBuilder.hxx> #include <NXOpen/BasePart.hxx> #include <NXOpen/Builder.hxx> #include <NXOpen/DateBuilder.hxx> #include <NXOpen/DateItemBuilder.hxx> #include <NXOpen/DateItemBuilderList.hxx> #include <NXOpen/Expression.hxx> #include <NXOpen/MassPropertiesBuilder.hxx> #include <NXOpen/NXObject.hxx> #include <NXOpen/PreviewPropertiesBuilder.hxx> #include <NXOpen/PropertiesManager.hxx> #include <NXOpen/SelectNXObjectList.hxx> #include <NXOpen/SelectObjectList.hxx> #include <NXOpen/Session.hxx> #include <NXOpen/Update.hxx> #include <NXOpen/ExpressionCollection.hxx> #include <NXOpen/Features_BlockFeatureBuilder.hxx> #include <NXOpen/Features_Feature.hxx> #include <NXOpen/Features_FeatureBuilder.hxx> #include <NXOpen/Features_FeatureCollection.hxx> #include <NXOpen/GeometricUtilities_BooleanOperation.hxx> #include <NXOpen/Part.hxx> #include <NXOpen/PartCollection.hxx> #include <NXOpen/Point.hxx> #include <NXOpen/PointCollection.hxx> #include <NXOpen/Preferences_PartModeling.hxx> #include <NXOpen/Preferences_PartPreferences.hxx> #include <NXOpen/Session.hxx> #include <NXOpen/Unit.hxx> #include <NXOpen/UnitCollection.hxx> using namespace NXOpen; extern "C" DllExport int ufusr_ask_unload() { return (int)Session::LibraryUnloadOptionImmediately; } extern "C" DllExport void ufusr(char *param, int *retCode, int paramLen) { Session *theSession = Session::GetSession(); Part *workPart(theSession->Parts()->Work()); Part *displayPart(theSession->Parts()->Display()); //创建块 Features::Feature *nullFeatures_Feature(NULL); Features::BlockFeatureBuilder *blockFeatureBuilder1; blockFeatureBuilder1 = workPart->Features()->CreateBlockFeatureBuilder(nullFeatures_Feature); blockFeatureBuilder1->SetType(Features::BlockFeatureBuilder::TypesOriginAndEdgeLengths); Point3d originPoint1(0.0, 0.0, 0.0); blockFeatureBuilder1->SetOriginAndLengths(originPoint1, "100", "100", "100"); Features::Feature *feature1; feature1 = blockFeatureBuilder1->CommitFeature(); blockFeatureBuilder1->Destroy(); //创建或编辑一个Null属性 feature1->SetAttribute("AAA"); feature1->SetAttribute("BBB", Update::OptionLater); //创建或编辑一个String属性 feature1->SetAttribute("标题C", "值C"); feature1->SetAttribute("标题D", "值D", Update::OptionLater); //创建或编辑一个Real属性 feature1->SetAttribute("标题E", 1.55); feature1->SetAttribute("标题F", 2.66, Update::OptionLater); //创建或编辑一个Integer属性 feature1->SetAttribute("标题G", 4); feature1->SetAttribute("标题H", 5, Update::OptionLater); //创建或编辑一个Reference属性 feature1->SetReferenceAttribute("标题I", "值I"); feature1->SetReferenceAttribute("标题J", "值J", Update::OptionLater); //创建或编辑一个Time属性 feature1->SetTimeAttribute("标题K", "14-Jun-2021 00:00:00"); feature1->SetTimeAttribute("标题L", "15-Jun-2021 10:00:00", Update::OptionLater); //后退标记 Session::UndoMarkId myUndoMark; myUndoMark = theSession->SetUndoMark(Session::MarkVisibilityVisible, NULL); //调用Update对象的DoUpdate方法来一次性更新所有的Attribute设置 theSession->UpdateManager()->DoUpdate(myUndoMark); } 阿飞 2021年6月14日
在这些函数中，NXString类型的title输入参数是NX对象属性的属性名称；
NXOpen::Update::Option是一个枚举类型的参数，定义如下：
当开发人员需要设置一系列的Attribute时，建议使用包含该输入参数的重载函数，并
设置更新选项为NXOpen::Update::OptionLater，最后显示调用Update对象的DoUpdate方法
来一次性更新所有的Attribute设置。
- 遍历对象属性
NXOpen API提供了遍历NX对象上某个类型的所有属性的方法

- 删除对象属性
NXOpen API提供了两种删除对象属性的方法，通过指定对象属性类型和属性名称删除
一个属性，通过指定对象属性类型删除所有该类型的属性，其定义方式如下：

- 获得属性对象值
NXOpen API为每种不同的对象属性类型提供了不同的对象属性值查询函数，开发人员根据
NX对象属性的类型，通过属性名称调用NXObject对象中不同的成员函数获得属性值，
这些函数的定义方式如下：
