i know there are "Wainscot Symbols" in the Library - but I find them pretty much worthless.   Here's how I do it:   1.  I use a Base Board Molding and a Chair Rail Molding for the bottom and top.   a.  The Base Board will be broken at Doors   b.  The Chair Rail will be broken at Doors and Windows 2.  Then I add a Wall Material Region between those moldings.   a.  This will be broken at both Doors and Windows 3.  Finally, I add Millwork Symbols or Cabinet Doors as embellishments.   a.
