Determining if a component is a reference

[dinomyar]

I have an issue where an assembly (A) contains two sub assemblies (B and C).  Sub Assembly B contains 4 parts. Sub Assembly C contains a "reference" to Sub Assembly B for constraint purposes and one other part. 

As I traverse the assembly tree, I end up counting the parts in Sub Assembly B twice. How can I tell if a component (B) in the assembly (C) is just a reference and not an actual instance of the component?

The BOM shows the correct counts, (5 parts total) so there is something somewhere that tells it that it is a reference only component.

I use the following function to get the files in the assemblies.

CComQIPtr<DocumentsEnumerator> docsenum;
HRESULT Result = assemblydoc->get_ReferencedFiles(&docsenum);

Do you need it in I-Logic?

[JelteDeJong · Accepted solution]

the information you seek is not stored in the document but in the ComponentOccurnce. (In your case that info is in assembly C)

In iLogic rule you would get this info like this:

Sub Main()

	Dim doc As AssemblyDocument = ThisDoc.Document
	Check(doc)

End Sub

Public Sub Check(doc As AssemblyDocument)
	For Each occ As ComponentOccurrence In doc.ComponentDefinition.Occurrences
		If (occ.Reference) Then
			MsgBox(occ.Name + " is a refrence")
		End If

		Dim refDoc As Document = occ.Definition.Document
		If (refDoc.DocumentType = DocumentTypeEnum.kAssemblyDocumentObject) Then
			Check(refDoc)
		End If
	Next
End Sub

I do not know if I would need it there. The assemblies I am dealing with are from a end user and who knows what they may eventually use.

Thank you. I was looping the occurrences to get the quantity counts and just had to add the reference check.
