Roof over Porch Length of house/cabin

[Gary_Ganu]

Ok, i'm done pulling my hair out,  Need some help.  I'm am trying to add a roof over a porch that goes the length of the house/cabin. I want it to start half way up the house/cabin main roof.  I've tried everything and i've been getting some pretty wild roofs.  Any and all advise would be much appreciated. The main roof is an 8/12 and looking to have the porch a 4/12.

Add a ceiling and roof over the deck. Open the room dialogue box (dbx) for the deck. On the left navigate to the "Structure" panel.... Under the ceiling heading click "Flat ceiling over this room"... doing this should activate the "Roof Over This Room" box as well.

 

Once you do that you will need to set the sides of the deck to gables. Click the long wall/rail of the deck and open the dbx. Navigate to the "roof" panel.  Under the "pitch" you have the option of adding an "Upper Pitch". Select that box and change the upper pitch to 8 and the main pitch to 4. You will have to jigger with the "in from baseline" or "Starts a height" value to get the look you want. You might even cut a live section through it so you can see how things are lining up and change the values mentioned so you can see the resulting affect under the roof, if that makes sense.
