Wow...Thank you so much for that video!  It is not exactly as I have it but it does answer a lot of questions.  Your roof over is very nice but since it's a mobile that would be problomatic because with a mobile home they tell you not to make hard connections due to ground heave. My home is on blocks, not lucky enough to have a stem wall or even a slab so my solution was to build it like a self supporting deck which some of it is.  I now have this and I can take it from here. Thanks again for the help, sorry if I was a PITA to get started.  

Hi Eric.  
Thanks for the help on this.  In the real world I have actually compleated this part of the extension build but am now in the planning stage of a second addition to the far right of the deck which will give me an additional bedroom.  What I am doing now is trying to recreate the plan in HD so I can visualize the new addition and it's interior layout.

I rebuilt the foundation but it did not put a foundation under the addition.  This is a mobile home so I am trying to not physically connect the addition to the home, it will be done as a stand alone structure rather like a deck and 3 season room would be.  Perhaps though, that is my problem because I have 4 walls defined in the addition with the one at the house being invisible.  Maybe this is not possible with Home Designer and perhaps for my purposes I should delete the invisible wall so that the addition becomes part of the home plan.  

Thank you.  I now have this

and this

But the gables are open as is the foundation on the new addition but at least it's in scale and looking better.  
Should I rebuild the foundation?  How do I go about closing up the gables? 

Thank you Eric.  Do you have a solution to my problem?  I have been googling, youtubing, watching videos, reading message boards

Hello

When placing a roof, how do you tell it that you don't have an attic?  I have trusses sitting on the exterior walls, no attic and no attic walls yet HD doesn't seem to allow that.  I have tried making attic walls invisible and turning off the automatic attic walls and then I get this .. a floating roof!  What do I have to do to get the roof to sit on the walls ??

Thanks
