I know the topic of cavity walls has been raised several times, to my knowledge, which is only a few years, but with it being raised again recently i was wondering if, in a future release, the drop down box with the wall hatching patterns could include an option for a cavity, this would enable people who are creating projects in order to print plans would have a much more realistic image without the need to actually create the cavity, which, i would imagine is a huge change to the basic programme, and would create issues with windows, doors, wall lengths, area calculation etc just a thought.
