NX Open is a powerful tool for automating NX CAD tasks. Below is source code that creates a new blank prt file with some predefined options. (first code block is in C sharp, and the other one is written in Visual Basic .Net)
Code in C Sharp
using System;
using NXOpen;
public class create_new_blank_part
{
public static void Main(string[] args)
{
Session theSession = Session.GetSession();
FileNew fileNew1;
fileNew1 = theSession.Parts.FileNew();
fileNew1.TemplateFileName = "Blank";
fileNew1.Application = FileNewApplication.Gateway;
fileNew1.Units = NXOpen.Part.Units.Millimeters;
fileNew1.NewFileName = @"C:\temp\test.prt";
fileNew1.UseBlankTemplate = true;
fileNew1.MakeDisplayedPart = true;
NXObject nXObject1 = fileNew1.Commit();
fileNew1.Destroy(); Part workPart = theSession.Parts.Work;
Part displayPart = theSession.Parts.Display;
UI.GetUI().MenuBarManager.ApplicationSwitchRequest("UG_APP_MODELING");
}
public static int GetUnloadOption(string dummy)
{
return (int)Session.LibraryUnloadOption.Immediately;
}
} Code in Visual Basic .NET
Imports System
Imports NXOpen
Module NXJournal
Sub Main (ByVal args() As String)
Dim theSession As Session = Session.GetSession()
Dim theUI As UI = UI.GetUI()
Dim fileNew1 As FileNew
fileNew1 = theSession.Parts.FileNew()
fileNew1.TemplateFileName = "Blank"
fileNew1.Application = FileNewApplication.Gateway
fileNew1.Units = NXOpen.Part.Units.Millimeters
fileNew1.NewFileName = "C:\temp\test.prt"
fileNew1.UseBlankTemplate = True
fileNew1.MakeDisplayedPart = True
Dim nXObject1 As NXObject = fileNew1.Commit()
fileNew1.Destroy()
Dim workPart As Part = theSession.Parts.Work
Dim displayPart As Part = theSession.Parts.Display
UI.GetUI().MenuBarManager.ApplicationSwitchRequest("UG_APP_MODELING")
End Sub
End Module
The code creates a new blank part using Siemens NX CAD software through the NXOpen API. The program starts by importing the necessary libraries and defining a class named create_new_blank_part. The Main function initializes a new NX session using Session.GetSession(). It then creates a new part using theSession.Parts.FileNew(), sets the part template to “Blank”, sets the application to “Gateway”, sets the units to “Millimeters”, sets the file name and path, and finally commits the new part using fileNew1.Commit().
After committing the new part, the code sets workPart and displayPart to the active work part and the active display part respectively using theSession.Parts.Work and theSession.Parts.Display. Finally, the code switches the application to the modeling application using UI.GetUI().MenuBarManager.ApplicationSwitchRequest("UG_APP_MODELING").
The GetUnloadOption function returns an integer value that specifies when the library should be unloaded. In this case, the value returned is Session.LibraryUnloadOption.Immediately, which unloads the library as soon as it is no longer needed.
