Creating a Box Bay.

[MaxStudio]

I'm trying to create a box bay with a window.  I've created the box bay using walls and offset the base of the walls to the appropriate height. unfortunately, once I offset the base of the box bay walls a hole remains  in the main wall of the house.  What is the best way to go about creating a box bay like this?

 

Thanks,

Derek

Use one continuous main wall, with a window in it. Set the window type to "Opening".
