Introduction 

Purpose: you want to force or compute the value of some 2D piping part attributes from the lineID

Code Example 1 

Code Example : simple : propagate description

//Linid :  LogicalOccurrence 
//--------------------------

Let ListMember(List)
Let i(Integer)
Let PipingLogicalOcc(LogicalOccurrence)
Let PipingLogicalInstance(RFLVPMLogicalInstance)
Let PipingLineIdRef(RFLVPMLogicalReference)

set PipingLineIdRef=Linid.Reference

ListMember=ListPipingLineIDMembers(Linid) 

If ListMember.Size() <> 0
{
    i = 1
    For i while i <= ListMember.Size() 
    {
        set PipingLogicalOcc = ListMember.GetItem(i)
        set PipingLogicalInstance = PipingLogicalOcc.Instance
        PipingLogicalInstance.V_description = PipingLineIdRef.V_description
    }
}
