Hello,

I am trying to delete curve by searching its name.
I have used below code and it is working in NX 9 and NX 10 but it is not working in NX 11.
Can anyone please help me to find my mistake ?

 Sub Main   
 
        theSession = Session.GetSession()
        workPart = theSession.Parts.Work
        displayPart = theSession.Parts.Display
        Dim Curves As CurveCollection = workPart.Curves
        Dim bodyname As String = Line
 
        For Each oCurve As Curve In Curves
 
            If oCurve.Name = bodyname Then
 
 
                Dim markId1 As Session.UndoMarkId
                markId1 = theSession.SetUndoMark(NXOpen.Session.MarkVisibility.Visible, "Delete")
                Dim notifyOnDelete1 As Boolean
                notifyOnDelete1 = theSession.Preferences.Modeling.NotifyOnDelete
                theSession.UpdateManager.ClearErrorList()
 
 
                Dim nErrs1 As Integer
                nErrs1 = theSession.UpdateManager.AddToDeleteList(oCurve)
 
                Dim nErrs2 As Integer
                nErrs2 = theSession.UpdateManager.DoUpdate(markId2)
                theSession.DeleteUndoMark(markId1, Nothing)

Hi All,

I am new here. I have a question that, can we encrypt vb code inside .vb file & run inside NX.?

I know that we can compile vb file into .dll & run in NX. But is there any option to encrypt vb file there by disallowing others to edit the code.

Thanks in Advance..

Journal to remove leaders from all balloons but selected

I'm currently looking for a way to have a journal remove the leaders from all the balloons on a drafting sheet besides ones that I have selected. I create stacked balloons so only one leader is required per stack. The idea would be to run the journal, select the balloons with leaders to be exempted, and have the leaders on all of the remaining balloons be removed.

Hello All,

Is it possible to make a plane surface in round figure by selecting a surface?

Hi! My experience with programming is limited, especially creating nx journals is a fresh topic for me. However I am trying to use inside my journal a default operation, like revolve or extrude, with user interaction - I mean specifying all settings and applying. After applying the journal should execute next steps (similarly like 'user entry' during recording macro). I have found no help on the Internet about this topic, so I would be very grateful for some tips

Standalone NX Open Scripting from External Script Files

Forums: 
Journaling / NXOpen API

I have been stuck some time trying to interface NX Open via external scripts that I have written. Here is an explanation of what I am trying to do:

I am currently designing classes and subroutines (in python) to automate NX assembly models which can edit the design variables and mass properties of the assembly. I have successfully written code snippets that generalize simple processes, such as translating and rotating objects, but the road block I am running into is the inability to import the NXOpen API into an external script which will run the desired class without opening NX at all. Every direction I go seems to be a dead end. I've tried editing my NXOpen environment variables to allow other python paths, and I've tried using the command "run_journal" only to realize I need the teamcenter installation to use this command which is out of our budget at the moment. In summary, I've been trying to run external files to execute NXOpen automation scripts outside of NX and cannot figure it out. I am willing to switch over to Java or VB if needed, but am not too sure how to do it in those languages as well.

If anyone has any insight or knowledge on this matter, any help would be greatly appreciated!

Thanks so much!

Journaling / NXOpen API

Hello,

I have a journal I found that is working fairly well but there is one improvement I am trying to make to it. This journal is for PDF export of every component in an open assembly. The journal walks through the assembly makes the component displayed, Updates views, exports pdf of sheet if it exists, moves on to next component.

I would like to modify the journal to Hide all components after it makes a component displayed. Then update views, export pdf.

Any help would be greatly appreciated.

Thank you,

I am looking for a way to select components in an assembly and then not only delete them from the model but also delete them from the computer. Something along the lines of selecting multiple components, hitting delete, have a confirmation window to confirm your action, if yes is selected the components are deleted from the model and from their respective file locations on the computer.

Move assembly components in structure including constraints

Journaling / NXOpen API

Hey,

NX seems to be unable to retain assembly constraints if you move a set of components in the assembly structure. In my opinion it should be able to retain the constraints that are still valid in the new location.

Is it possible to write a script that takes the currently selected components, asks for a new location in the tree, selects all common assembly constraints and moves the components and constraints (or recreates them in the new location)?

Thanks for any help in this matter.

I would like to find the location of all the Parts available in an Assembly on my monitor screen.

How can I declare my current monitor view of the assembly as View in order to pass it these Function inputs?

Help with selecting faces please

Hi wonderful NXJ community!

Could someone please tell me what is wrong with what I am doing. I am trying to select faces and return them as an array. It should be simple. I am migrating from "selectTaggedObject" which is a single face to "selectTaggedObjects" which is an array (right?)

My code is this

Public Function SelectFaces(ByVal propt As String) As Face()
 
        Dim title As String = "Select faces"
        Dim includeFeatures As Boolean = False
        Dim keepHighlighted As Boolean = False
        Dim selAction As Selection.SelectionAction = Selection.SelectionAction.ClearAndEnableSpecific
        Dim scope As Selection.SelectionScope = Selection.SelectionScope.AnyInAssembly
        Dim selectionMask(0) As Selection.MaskTriple
        Dim selectedFaces() As Face = Nothing
 
        With selectionMask(0)
            .Type = UFConstants.UF_solid_type
            .Subtype = 0
            .SolidBodySubtype = UFConstants.UF_UI_SEL_FEATURE_ANY_FACE
        End With
 
        Dim responce1 As Selection.Response = theUI.SelectionManager.SelectTaggedObjects(
            propt, title, scope, selAction, includeFeatures, keepHighlighted, selectionMask, selectedFaces)
 
        If responce1 = Selection.Response.Ok Then
            Return selectedFaces
        Else
            Return Nothing
        End If
 
 
    End Function

When debugging, this gives an error on the line with .selectTaggedObject( that says "Unable to cast object of type 'NXOpen.TaggedObject[]' to type 'NXOpen.Face[]'"

I don't understand. When I used the "selectTaggedObject" I passed in a variable of type Face for it to put what you selected into. Now i have a Face() and it should put all the faces you select into that array.

Am I missing something?

Pleeeeease help

PS. selectObjects says it has been superseded by selectTaggedObjects

Hi,

i'm facing a problem with the export option in NXOpen:
I created an non associative "extracted face" from a body.
Now i want to create a new part which only contains this extraced face.
I tried two options but they both don't work:

1. Option:
...
Dim nXObject2 As NXOpen.NXObject
nXObject2 = extractFaceBuilder1.Commit()
Dim Extracted_Face As NXOpen.Features.ExtractFace = Nothing
Extracted_Face = CType(nXObject2, Features.ExtractFace)
Dim BodyTag(0) As Tag
BodyTag(0) = nXObject2.Tag
Dim String_test As String = "D:\00_Database\test_part.prt"
theUFSession.Ps.ExportData(BodyTag, String_test)

2. Option:
...
Dim nXObject2 As NXOpen.NXObject
nXObject2 = extractFaceBuilder1.Commit()
Dim myOptions As UF.UFPart.ExportOptions
myOptions.params_mode = UF.UFPart.ExportParamsMode.MaintainAllParams
myOptions.new_part = True
Dim Name As String = "D:\00_Database\test_part.prt"
Dim BodyTag(0) As Tag
BodyTag(0) = nXObject2.Tag
theUFSession.Part.ExportWithOptions(Name, 1, BodyTag, myOptions)

I hope you can tell me whats my mistake with these options or an third option which works for my problem.

Thanks!

I asked a question on some ideas how to do the measurement to get the distance between the 2 components on an assembly file a few days ago. I did some study on some of the issues and I would like to understand some of the possible ways to let the program knows when to start and to stop a measurement.

In my example, how can I let the program know the left housing is a starting point, and the right housing is stopping point? There are multiple branches.

Hi

I have an assembly file with 4 parts of same name as (1.prt).I would like move them using a Text file where i have 4 lines as such denoting their respective positions in X,Y and Z.

100,0,0
-8000,1000,0
1000,1000,0
1000,1000,0

I am missing by the code a small bit linking the text file with the component,meaning when first line of the text file is read it has to move the 1 out of 4 parts by 1000,0,0 and so on.

please find the below code and kindly do the changes to it.

For i As integer = 0 To numsel-1
selobjs = theUI.SelectionManager.GetSelectedObject(i)

line = ReadLine(j+1, allLines)

Dim strings As String() = line.Split(",")
pt3.x = Double.Parse(strings(0))
pt3.y = Double.Parse(strings(1))
pt3.z= Double.Parse(strings(2))

workPart.ComponentAssembly.MoveComponent(selobjs,pt3, RotMat3)
Next

The problem with the above code it is just reading the first line and moving all the selected parts(4 Nos)by 1000,0,0.
But i need only the 1st one to be moved by 1000,0,0 and the second one by -8000,1000,0...

Please suugest

I have a journal written that when run will ask the user to input a layer number and then delete all objects from that layer (based on code from this site). The journal works fine in a single assembly. The problem I am running into is when I run the journal in a file with multiple sub-assemblies it will only delete objects from the layer in the top most level (Objects on the selected layer in subs are not deleted). Any suggestions?
