Tips and Tricks for Doing Split Wall Configurations

Hi Group
Looking for some tips and tricks on how to best do split wall configurations please.
As an example say you have a brick veneer wall and want to split a middle section with a splitstone feature wall and insert a window or a door exactly within the split section - how can you make it fit?

I can’t think of an instance where you would want to do this, can you create it in Sketchup and take a screenshot? Unless you are talking about a Wainscott wall?
