Subfloor/subfloor structure defaults for decks

[2B Design]

Hi all,

My first post, and I hope the answer to my query has not been staring at me in the face.

When I go to the structure tab of the dbx of a new Deck, the Subfloor thickness displays as '37 (D)' and the subfloor structure displays as '187 (D)', which are not the same as the values set up in Defaults, Floor Defaults. 'Normal' rooms seem to inherit these defaults, but not Decks.

I am assuming that there is a default setting for Decks somewhere, but I can't find it. I've checked the manual, training video's, etc to no avail.

So the question is: Where is the default dialog for Deck floor structures (if it exists)? or are they 'hardcoded' into the program?. They are weird numbers, even for us metric users here in Australia.

Thanks,
Bryan B.
