Create sketch in machining

[Anonymous]

I am trying to create a sketch in machining in a sub-weldment assembly with a ilogic code. But i continuously get this error:

Here is the code i am running from an external rule.Can anyoone help please??

Dim oDoc As Document
oDoc = ThisApplication.ActiveEditDocument

If oDoc.DocumentType = DocumentTypeEnum.kAssemblyDocumentObject 
	If  Not oDoc.ComponentDefinition.IsiAssemblyFactory Then
		If oDoc.ComponentDefinition.Type = objectTypeEnum.kWeldmentComponentDefinitionObject Then
			
			'Keep Selecting Faces, Hit Esc to finish
			Do
    			oFace = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kAllPlanarEntities, "Select a face")
    			If Not oFace Is Nothing Then 
        			Exit Do
    			End If
			Loop While Not oFace Is Nothing 
			
			oDoc.ComponentDefinition.Machining.edit
						
			oSketch = oDoc.ComponentDefinition.Sketches.Add(oFace)
                        oSketch.edit
                    End if
              End if
   End if

Anyone?

Hi, your code is not wrong in principle. What happens is that when selecting a face you should work with proxies to define in context of which assembly to work in your case in the subassembly. For this reason it returns the error and you would not easily create a sketch.
However, I think the simplest thing is to create a sketch directly with the manager and manager.
Try the code below. It is summarized and simple.

Dim oDoc As Document = ThisDoc.Document

Dim oSubAssy As ComponentOccurrence = ThisApplication.CommandManager.Pick(SelectionFilterEnum.kAssemblyOccurrenceFilter, "Select Occurrence")
If oSubAssy Is Nothing Then 
	Exit Sub
End If
	
If oSubAssy.Definition.Type = 100673280 Then '  objectTypeEnum.kWeldmentComponentDefinitionObject
	oSubAssy.Edit
	oSubAssy.Definition.Machining.edit
	'Create Sketch			
	ThisApplication.CommandManager.ControlDefinitions.Item("AppSketch2DWrapperCmd").Execute2(True)   
End If

  I hope it can be useful. regards

 Sergio.D.Suárez If able, can you show me the solution with the proxies or at leaset some code with proxies so i can understand how they are used. I intend to use this code as part of much larger codes.

Here there is information and in the API you can find more. The code you provide realizes what you are looking for and you will not have problems entering it in another major code. regards

 I have tried all morning but i just can't get the code right with proxies. Sergio.D.Suárez can you help me with that??
