Shelf Ceiling over part of another (adjoining) room is doing my head in....

[John_Charles]

Hello All..

 

I am trying to quickly knock up an as-built that has some separate rooms adjoining a living room that has a raked ceiling.  I'm having an issue in how to treat the adjoining rooms (one is a bath and the other is a powder room) as they each have shelf ceilings over only the part of them that 'protrude' into the raked ceiling area.... ie I am trying to figure out how to put a shelf ceiling over only a part of a room, and it's not working for either the walls, ceiling or roof planes.

 

In this image, the adjoining bathroom forms a box wall in the corner with a shelf ceiling over it, which then extends over the mini hall and pantry.  My approach was to draw my raked ceiling plane and then build my roof.

 

 

I have two issues that I can't for the life of me see a solution to.

 

1.  I have tried to replicate this structure by drawing an invisible wall to part of the bath (doted line is raked ceiling) and same again with the cupboard and hall.  That messed with the roof planes and walls where they intersected and the raked ceiling itself disappears.

             

 

2.  The second issue is how to generate the internal wall above and internal raked ceiling over each of the shelf ceilings when it is part of another room and without affecting the roof planes?

 

 

I have tried to manually adjust the walls by editing them manually but I'm sure there is a better way.

 

Am I overthinking this and should I just forget the shelf ceilings and draw some poly shapes/soffits to simulate what is needed?

 

Thanks for reading...
