This blog post is the first part of  3 part series on NX Journaling

The aim of this blog post is to select a part.


Before writing codes for journals, it’s easier to create a journal and then look at its code.

In NX 10.0, start recording a journal from tools -> journal

Do the operations that you want to repeat, and stop the recording of the journal from tools -> journal

Look at the code created from the operations at tools -> journal -> edit

The code might look like this: (Visual basic code)

' NX

Imports System
Imports NXOpen

Module NXJournal
Sub Main (ByVal args() As String)

Dim theSession As NXOpen.Session = NXOpen.Session.GetSession()
Dim workPart As NXOpen.Part = theSession.Parts.Work

Dim displayPart As NXOpen.Part = theSession.Parts.Display

' ----------------------------------------------
' Menu: File->Show Dimensions
' ----------------------------------------------
Dim markId1 As NXOpen.Session.UndoMarkId
markId1 = theSession.SetUndoMark(NXOpen.Session.MarkVisibility.Visible, "Show Dimensions")

Dim extrude1 As NXOpen.Features.Extrude = CType(workPart.Features.FindObject("EXTRUDE(2)"), NXOpen.Features.Extrude)


Dim nErrs1 As Integer
nErrs1 = theSession.UpdateManager.DoUpdate(markId1)

' ----------------------------------------------
' Menu: Tools->Journal->Stop Recording
' ----------------------------------------------

End Sub
End Module

This article helps in understanding more about understanding what each line of the code does, do read it if the above lines of code boggles you.

Our aim now is to modify this code to let user select the part that he requires, and to display its name in a popup window.

A listing window is a window like a popup which we are using to display dimensions.

getSelectedObject is a function that gets the selected object. This example aslo demonstrates how to write functions in VB.

Once the part is selected, its name and type are selected in the Listing window.
