C# drawing replace reference model

[hwu]

I have drawing saved to different location, then need to replace its reference model (there is only one reference model). I am wondering if there are C# code to do this?

thanks,

HWU

in a drawing Document, you have access to the object DrawingDocument.File.ReferencedFileDescriptors which you have read/write access to it.

in VBA, I change my reference like this:

For Each oFileDescriptor In NewDrawingDocument.File.ReferencedFileDescriptors
    If oFileDescriptor.Fullfilename = DocToCopy.Fullfilename Then
        oFileDescriptor.ReplaceReference NewFilePath
    End If
Next oFileDescriptor
    
NewDrawingDocument.PropertySets.item("Design Tracking Properties").item("Part Number").Value = fso.getbasename(NewFile)

NewDrawingDocument.PropertySets.item("Design Tracking 
Properties").item("Creation Time").Value = Now()

NewDrawingDocument.DisplayName = fso.getbasename(NewFile)

In plain iLogic (which uses VB.NET) here is a single line of code to replace the referenced model of a drawing.

(This assumes a single model reference, not multiple.)

ThisDrawing.Document.Sheets(1).DrawingViews(1).ReferencedDocumentDescriptor.ReferencedFileDescriptor.ReplaceReference("C:\Temp\OtherFile.iam")

And here is an example that separates the variables out.

Dim oDoc As DrawingDocument = ThisDrawing.Document
Dim oNewModelFile As String = "C:\Temp\OtherFile.iam"
Dim oFD As FileDescriptor = oDoc.ReferencedDocumentDescriptors(1).ReferencedFileDescriptor
oFD.ReplaceReference(oNewModelFile)
oDoc.Update()

Thank you, Yan,

I cannot convert  your code to C#.

Can you please have it in C#?

Here is a single line of iLogic (VB.NET) code to replace the model reference within a drawing.

(This assumes just one model reference within the drawing.)

ThisDrawing.Document.Sheets(1).DrawingViews(1).ReferencedDocumentDescriptor.ReferencedFileDescriptor.ReplaceReference("C:\Temp\OtherFile.iam")

And here is a version that breaks things down into more variables.

Dim oInvApp As Inventor.Application = GetObject(,"Inventor.Application")
Dim oDrawDoc As Inventor.DrawingDocument = oInvApp.ActiveDocument
Dim oNewModelFile As String = "C:\Temp\OtherFile.iam"
Dim oFD As Inventor.FileDescriptor = oDrawDoc.ReferencedDocumentDescriptors(1).ReferencedFileDescriptor
oFD.ReplaceReference(oNewModelFile)
oDrawDoc.Update()

Sorry.  When I originally posted, it stalled out and gave an error indicating it didn't go through, so I reposted, then found out the original went through.

[hwu]

Thank you!

When I convert your code to C#, shows:

DrawingDocument.ReferencedDocumentDescriptors() cannot be used as method.

I have no idea how to fix this.

Perhaps it just doesn't like the format.  Maybe it would work better if you replaced:

ReferencedDocumentDescriptors(1).ReferencedFileDescriptor

 with

ReferencedDocumentDescriptors.Item(1).ReferencedFileDescriptor

Or to break it down even further:

Dim oInvApp As Inventor.Application = GetObject(,"Inventor.Application")
Dim oDrawDoc As Inventor.DrawingDocument = oInvApp.ActiveDocument
Dim oNewModelFile As String = "C:\Temp\OtherFile.iam"
Dim oDDs As Inventor.DocumentDescriptorsEnumerator = oDrawDoc.ReferencedDocumentDescriptors
Dim oDD As Inventor.DocumentDescriptor = oDDs.Item(1)
Dim oFD As Inventor.FileDescriptor = oDD.ReferencedFileDescriptor
oFD.ReplaceReference(oNewModelFile)
oDrawDoc.Update()

Sorry, I'm not as familiar with C# as I am with VB.NET, but here's my attempt at the C# version of this code:

Inventor.Application oInvApp = GetObject(,"Inventor.Application");
Inventor.DrawingDocument oDrawDoc = oInvApp.ActiveDocument;
String oNewModelFile = "C:\Temp\OtherFile.iam";
Inventor.DocumentDescriptorsEnumerator oDDs = oDrawDoc.ReferencedDocumentDescriptors;
Inventor.DocumentDescriptor oDD = oDDs.Item(1);
Inventor.FileDescriptor oFD = oDD.ReferencedFileDescriptor;
oFD.ReplaceReference(oNewModelFile);
oDrawDoc.Update();

Thank you,

there is no "Item" for choosing after "oDDs".

You might use C# indexer, as : 

ReferencedDocumentDescriptors[1]

[yan.gauthier]

he is how to handle IEnumerator in C#

IEnumerator fileEnumerator = drawingDocument.ReferencedFileDescriptors.GetEnumerator();
//Set index at position 0
fileEnumerator.Reset();

while (fileEnumerator.MoveNext())
{
    if (fileEnumerator.Current is FileDescriptor fileDescriptor)
    {                            
        fileDescriptor.ReplaceReference("FileString");
    }
}

[hwu]

Thank all of you!

the code has no any problem, but it does not do the job.

HWU

[yan.gauthier]

if you debug your code, do you get inside the if statement ?

Also, I just remembered that FileDescriptor.ReplaceReference works only if files share Ancestry. So the new file has to be a copy.

[hwu]

No. Not get inside of if statement.

[yan.gauthier]

what is the object held by current ?

[hwu]

Thank you, Yan,

Nothing happened. just stuck there.
Do you have any ideas?

Hi, I tested the code, the output of that is a ReferencedFileDescriptor, not a FileDescriptor. It seems to be different from what you can get in VB.

          IEnumerator fileEnumerator = drawDoc.ReferencedFileDescriptors.GetEnumerator();
                
                //Set index at position 0
                fileEnumerator.Reset();

                while (fileEnumerator.MoveNext())
                {
                    if (fileEnumerator.Current is ReferencedFileDescriptor referencedFileDescriptor)
                    {
                        //fileDescriptor.ReplaceReference("FileString");
                        referencedFileDescriptor.PutLogicalFileNameUsingFull("FileString");
                    }
                }

I would try this method to see if it works.

Hi Yan,

I just get a different way to meet what I need:

1. Create an iLogic,  triggered by iProperty, to replace the referenced model

2. Using C# to save the drawing to a different location with different name, set new drawing with new Part Number

Hopefully can find a direct way to do this.

Best Regards,

HWU

Our company IT guy creates above code for me and it works. In the past, the codes didn't work, I guess we didn't add "update()".

[talha.tufan523TD]

Can you share code block of the Function called UpdateDrawingView?
