Floor layers definition

[rfcomm2k]

I need to change the floor defaults to add a layer of gypcrete for radiant floor heat. I opened the floor structure defaults dbx, but cannot figure out how to add layers.

If you don't have an "Edit" button next to "Floor Structure" in your Floor or Room Defaults, then your Pro 2014 version may not have that ability (I don't recall when it was added).
