Identifying occurrences in assembly

[TommySWE]

I'm trying to identify different occurrences in my assembly and its subassemblies,

so far I'm traversing down the assembly tree like this;

Sub Main()
On Error Resume Next

Dim oDoc As AssemblyDocument
oDoc = ThisDoc.Document

oDoc.ObjectVisibility.AllWorkFeatures() = True

Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = oDoc.ComponentDefinition
oAsmCompDef.RepresentationsManager.DesignViewRepresentations.Item("Default").Activate

Dim occBoolean As Boolean
occBoolean = False
	
Dim oOcc As Inventor.ComponentOccurrence
For Each oOcc In oAsmCompDef.Occurrences
	oOcc.SetDesignViewRepresentation("Default", True)
	MsgBox(oOcc.Definition)
	If oOcc.SubOccurrences.Count = 0 Then
    Else
        Call processAllSubOcc(oOcc)
	End If
Next

InventorVb.DocumentUpdate()
End Sub

Private Sub processAllSubOcc(Occ As Inventor.ComponentOccurrence)
	Dim oSubCompOcc As ComponentOccurrence
    For Each oSubCompOcc In Occ.SubOccurrences

        If oSubCompOcc.SubOccurrences.Count = 0 Then
        Else
			oSubCompOcc.Visible = occBoolean
            Call processAllSubOcc(oSubCompOcc)
        End If
    Next
End Sub

 The problem is that I can't tell the occurrences apart as they are just "occurrences". Well, I can tell the assemblies and part documents by looking at the DefinitionDocumentType property of the component occurrence, but what about work features? How do I identify work planes or axes as occurrences in an assembly?

Help is much appreciated!

Hi,

I'm not sure what exactly you need but the best thing to get familiar with the API is to use VBA:

If you need to get to a work feature then you need to go inside the definition of the occurrence (inside the document) and then get a proxy for it:

and

Thanks a million! I will look into your suggestions, especially the VBA Watches. This far I've only been using the Inventor help and VBA editor object browser to find my way around. I also got the API object model which is of great help, but sometimes I find it really difficult to find specific objects or properties, so your suggestions will be of much help.
