Trace is not only to enable you to trace and draw over things. You can also show or print the whatever you are showing as a trace in your plans. As far as I know there is no way to have only windows and doors showing without the enclosing walls so it might no do what you want it to do.
In the Trace Palette you can select which items you would like to show on the Trace drawing. See attached image.
