As informações necessárias sobre a biblioteca NXOpen podem ser encontradas no site oficial .
A pasta raiz do NX contém as bibliotecas padrão de que precisamos, bem como exemplos:
- C: \ Arquivos de programas \ Siemens \ NX 12.0 \ NXBIN com extensão jar
- C: \ Arquivos de programas \ Siemens \ NX 12.0 \ UGOPEN com extensão jar
- C: \ Arquivos de programas \ Siemens \ NX 12.0 \ UGOPEN \ SampleNXOpenApplications \ Java.
Para simplificar a escrita de código, você pode usar o registro de suas ações em um arquivo de texto como base. Por padrão, Unigraphics NX grava em Visual Basic, mas nas configurações você pode alterá-lo para Java ou qualquer outro disponível:

Aqui está um exemplo de registro em um arquivo de texto.

Agora ele constrói uma malha apenas nas superfícies que são especificadas no código e, se houver menos ou mais delas, e seus nomes forem diferentes, então nx dará um erro ao executar nosso código. Portanto, precisamos modificar o código adicionando exceções try / catch e encontrar uma maneira de não nos ligarmos ao número de faces poligonais.
Eu fiz assim:
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) {
Aqui está o resultado final executado no programa:
