Andrew, we did this and we removed it, because users complained about the flip side. If you add an architrave to on sides of a door and it remembers on an external wall and then you add a door on an internal wall it is easy to forget this was done unfortuantely there are more internal doors than external doors that have architraves 2 sides so we need to make it the same. The majority of doors have architraves 2 sides and the majority of windows have architraves one side. It is a swings and round about conundrum mate. I hope it's not a deal breaker, Understand your frustration yet I assume you would be equally frustrated if by mistake all of your internal doors only had one architrave? I would be interested in hearing if any body else agrees with Andrew C, it's a 10-minute change yet we have to work in majority rules scenario.
