.net做UG NX二次开发（VB.net） / NX Secondry Dev. with .net u

用.net语言（C#、VB等）开发UG NX二次开发，一定要弄清楚NXOpen和NXOpen.UF的区别。可以看看我以前发的帖子。

以下内容来自与http://bbs.icax.cn/491598p1p1

真的要特别感谢名叫“苏州人”的网友贴了这么多代码。不过这些代码的也是属于NXOpen.UF的使用，不是真正的NXOpen。操作录制的才是真正的NXOpen形式（参见我以前的帖子）

不过，广告部分我就不贴了，呵呵。

第一个例子：怎样用VB.NET在UG中创建一个点? Option Strict Off Imports System Imports NXOpen Imports NXOpen.UF Imports NXOpen.UI Imports NXOpen.Utilities Module CreatePoint Dim s As Session = Session.GetSession() Dim ufs As UFSession = UFSession.GetUFSession() Sub Main() Dim sp As New Point3d(0,0) Dim thePoint As Point = s.Parts.Work.Points.CreatePoint(sp) End Sub Public Function GetUnloadOption(ByVal dummy As String) As Integer GetUnloadOption = UFConstants.UF_UNLOAD_IMMEDIATELY End Function End Module第二个例子：怎样用VB.NET在UG中创建一个条线? Option Strict Off Imports System Imports NXOpen Imports NXOpen.UF Imports NXOpen.UI Imports NXOpen.Utilities Module template_code Dim s As Session = Session.GetSession() Sub Main() Dim sp As New Point3d(0,0) Dim ep As New Point3d(10,10,0) Dim theLine As Line = s.Parts.Work.Curves.CreateLine(sp,ep) End Sub Public Function GetUnloadOption(ByVal dummy As String) As Integer GetUnloadOption = UFConstants.UF_UNLOAD_IMMEDIATELY End Function End Module 第三个例子：怎样用VB.NET在UG中创建一个圆柱，然后更改它的颜色?
