Eric,
I've done the signature thing as you suggested. I was already attempting to use Nana wall, their WD66 product is almost exactly the right thing. The challenge I was having with it is it is behaving like an object, and not like a door or a window.
I've watched the video's on how to do this, and I think I'll be able to figure it out. Mine is a little different as the bottom of door is at the height of the kitchen work surface. It's fighting me a little, but I think I'll be able to figure out what is blocking me from placing the Nana wall in the door opening. I think the issue is that I'm placing it at kitchen work surface height.
and there are differences in floor height between the kitchen and the alfresco.
Thanks for your assistance.
