Wall Type Definition - Extension

[ComputerMaster86]

Inside the wall type definition dialog box I am trying to make use of the extension setting.   I can not for the life of me get wall layers to extend past the concrete floor or by using a negative number get them to extend upward exposing the concrete floor a little.  What am I doing wron?

Below is inside the zip is my X16 plan I was playing around the extension settings with.

I added foundation walls on the floor below.  The foundation walls were placed to have the same footprint as my walls on the 2nd floor.  Those foundation walls were set to hidden, no room definition and no locate.  I also turned off the sill plate and footing.  I was then able to get it to do something.  It frustrates me that you have to have some form of a wall below to get the extension to do anything.

Pictured below is pretty much what I was after.  I normally don't get this detailed on my projects.  I was challenging my self at creating the look of steel ratguard trim using an actual to size molding profile.  The ratguard fastens to a treated grade board at the bottom of a post-framed wall.  The steel sheet metal panel sits on the ledge of the steel rat guard trim.  I have been experimenting with the extension wall layer feature too see if I could come up with something like I have pictured below.  I wish we didn't have to have walls placed on floor below to make use of extension.

Under your Wall Ddefinition, Wall Properties, Foundation to Exterior of Layer select the steel siding (outermost layer).

See if that corrects the problem.

In our neck of the woods we use a 1 1/2" x 1 1/2"

notch on the edge of the concrete slab in lieu of

a rat guard. The base plate sits on top of the slab

and the metal siding extends down an inch and a 

half to sit in the notch.
