I made some progress on this. Seems on the 2013 /14 version i imported the database from their is a difference in how the material in made. If i add the thickness to the "Other" tab they do show up. By default they are under "Duct". But i don't see the "Type" option when creating a new material. I don't see any of this in the 3013 version. However, when selecting the material i add the the Other tab i cant get it to nest.
