Change visibility for Surfaces in an Assembly

[They_Call_Me_Jake]

Not sure what I'm doing wrong or if it is a bug but if I could get some help I would appreciate it. I have and Assembly with some Sub-Assemblies in it. In those Sub-Assemblies are some parts with surfaces that where from copying other parts into it. We use those copied in surfaces to do a sculpt but it leaves the surface visible. I have tried numerous ways to try and turn off the visibility but nothing I try seems to work. Does anyone have an idea of what I am doing wrong here.

Sub Main()
	Dim oAsm = ThisDoc.Document
	Dim oAsmDef As ComponentDefinition = oAsm.ComponentDefinition
		
	HideCompositeSurfaces(oAsmDef, "Carriage Base:1")
	
End Sub 

Sub HideCompositeSurfaces(oAsmDef As ComponentDefinition, targetName As String)
	
	Dim target As ComponentOccurrence = Nothing
	Dim oLeafOccs As ComponentOccurrencesEnumerator = oAsmDef.Occurrences.AllLeafOccurrences
	Dim oOcc As ComponentOccurrence

    For Each oOcc In oLeafOccs		
        If oOcc.Name = targetName Then			
			target = oOcc			
		End If		
	Next
	
	Dim oContainingOccurrence As ComponentOccurrence = target.ContainingOccurrence
	Dim oContainingOccurrenceDef As ComponentDefinition = oContainingOccurrence.Definition
	
	For Each oWorkSurface In target.Definition.WorkSurfaces
			
'			Dim oWorkSurfaceProxy As WorkSurfaceProxy = Nothing
'			oContainingOccurrence.CreateGeometryProxy(oWorkSurface, oWorkSurfaceProxy)
			oWorkSurface.Visible = False
			
		Next
	
End Sub

It sounds to me like you might benefit from setting up DesignViewRepresentations at each level of the assembly structure, starting with the part.  Create a DVR in the Part, then turn those surfaces off, and that DVR will record that setting.  Then in the sub assembly, create a DVR, and set the component representing that part to the DVR you created in the part, and that setting will be recorded in its DVR.  Then in your top assembly, create a DVR and set the component that represents the sub assembly to its DVR.  That's the normal, manual way of handling those sorts of things.

@WCrihfield thanks for the reply. I'm wanting to do this thru code instead of manually. I have actually done this before and I have copied my code that does in fact work into this iLogic rule but for some reason it's not working here when it works in external code.
