1 用.net2003建立一个控制台应用程序   2 将目录ugii\managed下除ManagedLoader.dll外的dll文件加入到你的工程里面的References   3 将下面的代码复制到你的Main函数里面                theSession = Session.GetSession();                                theSession.Parts.NewDisplay("d:\\1.prt",NXOpen.Part.Units.Millimeters);                NXOpen.Features.Feature nullFeatures_Feature = null;                NXOpen.Part pp=theSession.Parts.Work;                myblock = pp.Features.CreateBlockFeatureBuilder(nullFeatures_Feature) ;                Point3d ps = new Point3d(0.0, 0.0, 0.0);                myblock.SetOriginAndLengths(ps, "100", "100", "100");                myblock.CommitFeature();                NXOpen.PartSaveStatus status;                theSession.Parts.Work.Save(NXOpen.Part.SaveComponents.True,NXOpen.Part.CloseAfterSave.False, out status);       4 修改项目的属性，将输出文件定位到ugii目录   5 编译直接运行生成的exe文件（不需要启动UG）   6 在d:\下会生成文件1.prt    using System;   using NXOpen;   using NXOpen.UF;       namespace drawBlock   {      class Class1      {        public static Session theSession;        public static UFSession theUFSession;            static void Main(string[] args)        {          theSession = Session.GetSession();           theUFSession = UFSession.GetUFSession();           theSession.Parts.NewDisplay("d:\\1.prt",NXOpen.Part.Units.Millimeters);               NXOpen.Features.Feature nullFeatures_Feature = null;           NXOpen.Part pp=theSession.Parts.Work;               NXOpen.Features.BlockFeatureBuilder myblock=pp.Features.CreateBlockFeatureBuilder(nullFeatures_Feature) ;          Point3d ps = new Point3d(0.0, 0.0, 0.0);           myblock.SetOriginAndLengths(ps, "100", "100", "100");           myblock.CommitFeature();           NXOpen.PartSaveStatus status;           theSession.Parts.Work.Save(NXOpen.Part.SaveComponents.True,NXOpen.Part.CloseAfterSave.False, out status);        }      }   }
