Link value from Assembly to subassembly and subassembly's part

[Marcus_Chong]

Hi,

I am trying to send value of parameter from assembly to it's subassembly and subassembly's part. Both subassembly and subassembly's part consists of model states. 

For example, 

Assembly.iam 

 --> Subassembly1.iam (Model State 1)

        --> Part1 (Model State 1)

--> Subassembly1.iam (Model State 2)

        --> Part1 (Model State 2)

Below is what I do.

Sub Main()
	
	Dim oAsmDoc As AssemblyDocument = ThisApplication.ActiveDocument
	Dim oOcc As ComponentOccurrence
	Dim ofacDoc As Document
oOcc = oAsmDoc.ComponentDefinition.Occurrences.ItemByName("PIPE 1")
		ofacDoc = oOcc.Definition.FactoryDocument
		
		ofacDoc.ComponentDefinition.ModelStates.Item("SC-SF-PIPE-01").Activate()
		ofacDoc.ComponentDefinition.Parameters.ModelParameters.Item("Pipe_OD").Units = UnitsTypeEnum.kCentimeterLengthUnits
		ofacDoc.ComponentDefinition.Parameters.ModelParameters.Item("Pipe_OD").Value = PipeOD(Pipe_DN)

End Sub

The above code, I can send the parameter value to subassembly model state. If i do the same at subassembly, assuming that assembly value is sent to subassembly, then running event trigger, I thought it will run the rule and send the similar parameter from subassembly (Model State) to subassembly's part (Model State). 

It is not working this way.

Is there any code I can use?
