Multiple rooms with 1 long dormer with Gamble Roof

[Iamsecond]

Hello All,

I have hit a bit of a wall (no pun intended). I am trying to make the area that is covered by a large dormer across the back of the house into three distinct rooms.  2 Bedrooms, and a bathroom. 

I am using the auto dormer and everything is fine until I try to draw the 2 walls in the blueprint.  It I leave them how they are nothing strange happens except I have the open space near the outside exterior wall.  But if I connect to the interior wall to the exterior dormer things go sideways.  I get this message, "

 

Warning #272003205
Cannot find walls for the room to which the back of this dormer should connect.

 

I know there has to be a way to do this as I have seen a few projects like this but no one is talking about how to accomplish this task outside of using multiple small dormers across the back but that is not the look I am going for.   The windows are just chucked in there for placement purposes not their final destination. I have followed all the dormer videos I can find but none of them discuss crossing multiple rooms with a single long dormer. 

 

I have designed the house with as a 1.5 story, ignoring the 2nd floor and the upstairs has living space with an Attic above in the peak. 

 

If you need the plan or more info please ask and thanks for the help. 

 

I am using chief architect X16 on a Mac. 

 

Please Help this is the last part of this design. Thanks

Please post your plan.

Since it is auto dormer you need to select it in plan view and in the edit tools explode it. Then extend the roof to where you want it and also the roof hole to the side walls.

You'll also need to place a knee wall. This article explains it very well (scroll down about 2/3 to 'Requirement: Auto Dormers must intersect knee walls running perpendicular to the pitch of the base roof plane in the living or attic space directly below.'

Click on all of these walls and make sure that none of them are designed as "attic". 

They need to have room definition properties.

Hello gents. After I posted i kept watching more videos to see if there was something I was missing.  Well I found a video from 2016 and there is section that answered all my questions. 

 

I did it manually and everything jumped into place.  I will post the video and the the final plan.  I think it had something to do with the auto dormer feature and it does not like adding rooms where the dormer is.  

 

this video is not wildly different from the chief architect videos except is shows what happens to the walls when you do a manual dormer that is this big.

 

I was able to do a dormer across the back side of the house and put 2 bedrooms and a bathroom. 

 

 

 

 

All the videos were correct but the one I found helped me understand the need for manually building the large dormer.

 

Thank You all
