Help With Fixing Roof 12/12 Pitch Alignment/Slopes

[ThomasR89]

Hey guys. I'm new here. Only been working with the software for about a week. I am trying to create a two story house with an "open to below" living/foyer area but I'm having trouble with the roof. Every time I try and clock a plane (green dotted line) to move something it goes terribly wrong. Somehow the connections no longer meet up and I end up with walls jetting out of the roof. I'm trying to just adjust the places where the roof lines slope downward. I want them to just run straight across but the only way I seem to be able to do that is to make things a perfect square, which I don't want.

 

Anyone know the fix?

 

Thank you.

If you can post the plan file I can take a look at it later this evening.

Here is the plan file. Any help would be greatly appreciated. I've searched for videos and other directions but I can't find anything for a complex hip roof like this.

 

I want the living room, foyer and dining room to be "open to below"  from the second story, which I'm also having trouble with as I don't know how to move the walls up or why the staircase isn't showing on the 2nd floor view.
