Add flange to part in assembly

[askokk]

Hello.

Im just getting started with API and would like you to show me some guidelines.

For my first project Im trying to following:

Assembly document is open. In this assembly there is a sheet metal part called "BAR"

Now what i want to do is select one of sheet metal part edges using pick function and add a flange to that edge.

Something like this was able to do that in in part environment:

Public Sub addflange()

Dim oSheetMetalDoc As PartDocument
Set oSheetMetalDoc = ThisApplication.ActiveDocument

Dim oCompDef As SheetMetalComponentDefinition
Set oCompDef = oSheetMetalDoc.ComponentDefinition

Dim oSheetMetalFeatures  As SheetMetalFeatures
Set oSheetMetalFeatures = oCompDef.Features


'Pick edge
Dim oEdge As Object
Set oEdge = ThisApplication.CommandManager.Pick(kPartEdgeFilter, "edge")

'Add edge to edges collection
Dim oEdgeC As EdgeCollection
Set oEdgeC = ThisApplication.TransientObjects.CreateEdgeCollection
Call oEdgeC.Add(oEdge)

'Create flange definiton
Dim oFlangeDef As FlangeDefinition
Set oFlangeDef = oSheetMetalFeatures.FlangeFeatures.CreateFlangeDefinition(oEdgeC, "45 deg", 20)

'Add flange
Dim oFlangeFeature As FlangeFeature
Set oFlangeFeature = oSheetMetalFeatures.FlangeFeatures.Add(oFlangeDef)

End Sub

But I need it to be done in ASSEMBLY environment. 

So that the active document  would be assembly document, select PART edge from ASSEMBLY document  (i think this is where i get lost) and then add flange to this sheet metal part file.

Am I on heading to the right direction?

Any suggestions?

Been looking around a little.. are "Face Proxies" something I have to create here?

Got it working.

It turns out that "Edge proxies" are allready there.. no need to create one:D

I just had to use EdgeProxy.NativeObject instead of just Edge.
