Component Group in NXOpen

[jiloebel]

Hi all,

I've done quite a bit of searching on this, and read through the help files, but can't seem to get this to work. I am trying to make a (simple for now) program to select components and add them to a component group. (I know this can be easily done without a journal, but this will eventually be merged into a journal that will be doing several other things.)

I started of by using an example code for selecting objects and tried adding the component group in. Here's what I have so far:

Option Strict Off
Imports System
Imports NXOpen

Module NXJournal
    Sub Main()

        Dim theSession As Session = Session.GetSession()
        Dim workPart As Part = theSession.Parts.Work
        Dim displayPart As Part = theSession.Parts.Display
        Dim lw As ListingWindow = theSession.ListingWindow
        Dim mySelectedObject As Assemblies.Component
        Dim Group1 As Assemblies.ComponentGroup

        lw.Open()
        
        'Continue prompting for a selection until the user
        '  presses Cancel or Back.
        Do Until SelectAnObject("Hey, select something", _
                               mySelectedObject) = Selection.Response.Cancel
            lw.WriteLine("Object Tag: " & mySelectedObject.Tag)
            lw.WriteLine("object Name: " & mySelectedObject.Name)
            lw.WriteLine("Object Type: " & mySelectedObject.GetType.ToString)
            lw.WriteLine("")
            Group1.AddComponent(mySelectedObject, 0)

        Loop


        ' The close method closes the text stream to the window,
        '   it does not close the window itself
        '   (use the .CloseWindow() method for that).
        ' Also, if you are using the listing window to write
        '   to a file, the close method will clean up and close the file.
        lw.Close()

    End Sub

    Function SelectAnObject(ByVal prompt As String, _
               ByRef selObj As NXObject) As Selection.Response

        Dim theUI As UI = UI.GetUI
        Dim cursor As Point3d
        Dim typeArray() As Selection.SelectionType = _
            {Selection.SelectionType.All, _
                Selection.SelectionType.Faces, _
                Selection.SelectionType.Edges, _
                Selection.SelectionType.Features}

        Dim resp As Selection.Response = theUI.SelectionManager.SelectObject( _
                prompt, "Selection", _
                Selection.SelectionScope.AnyInAssembly, _
                False, typeArray, selobj, cursor)

        If resp = Selection.Response.ObjectSelected Or _
                resp = Selection.Response.ObjectSelectedByName Then
            Return Selection.Response.Ok
        Else
            Return Selection.Response.Cancel
        End If

    End Function

End Module

There issue I'm having is I'm not sure how to initialize the ComponentGroup (group1), so the line "Group1.AddComponent(myselectedobject,0)" is just giving an error.

Any help would be appreciated.

Thanks!

Do you want to create a new component group in the current work part, or do you want to create a new component group?

If you want to use an existing group, iterate through the workpart.ComponentGroups collection to find the one you want.

If you want to create a new group, use Group1 = workpart.ComponentGroups.CreateComponentGroup(...).

Thanks cowski! That's exactly what I needed. Is there any way to control turning on/off the component groups through a Journal?
