使用Java中的NXOpen库为Unigraphics NX创建实用程序的示例

我决定告诉任何有兴趣的人，您可以使用NXOpen库和Java编程语言为Unigraphics NX创建任何实用程序，例如，我的实用程序将在所有自由物体和面上建立一个二维网格（这对于优化问题很有用）。



可以在官方网站上找到有关NXOpen库的必要信息。



NX根文件夹包含我们需要的默认库以及示例：



  • C：\ Program Files文件\ Siemens \ NX 12.0 \ NXBIN带jar扩展名
  • C：\ Program Files文件\ Siemens \ NX 12.0 \ UGOPEN带jar扩展名
  • C：\ Program Files \ Siemens \ NX 12.0 \ UGOPEN \ SampleNXOpenApplications \ Java。


为了简化代码编写，您可以将操作日志记录到文本文件中作为基础。默认情况下，Unigraphics NX以Visual Basic语言编写，但是在设置中，您可以将其更改为Java或可用列表中的任何其他语言：







这是登录文本文件的示例。

现在，它仅在代码中指定的那些表面上构建网格，并且如果它们数量较少或更多，并且它们的名称不同，则在运行我们的代码时nx会给出错误。因此，我们需要通过在代码中添加try / catch异常来完善代码，并提出一种方法，使我们不会绑定到多边形面的数量。



我这样做是这样的： 



        try {

            for (int i = 1; i < 20; i++) {
                 obj="object"+i;
                cAEB="cAEBody"+i;
                cAEF="cAEFace"+i;
                adde="added"+i;

                //Object objects = new Object();
                nxopen.DisplayableObject [] obj  = new nxopen.DisplayableObject[1];
                nxopen.cae.CAEBody cAEB = ((nxopen.cae.CAEBody)workFemPart.findObject(("CAE_Body"+"("+i+")")));
                nxopen.cae.CAEFace cAEF = ((nxopen.cae.CAEFace)cAEB.findObject("CAE_Face"+"("+i+")"));
                obj[0] = cAEF;
                boolean adde;
                adde = mesh2dBuilder1.selectionList().add(obj);

           }
        } catch (Exception ex) {


这是程序中执行的最终结果：
