Best practice for a single wall that changes 'interior/exterior' at a specific height.

[ChiefRushT]

Good morning all,

 

I've been struggling with the best practice for a wall I have.  One side I have is fully exterior.  Above a roofline, the interior side becomes an exterior side as well (I have different interior heights with overlapping shed roofs).  What's the best way to manage this?  I've been using 'Lower wall type if split by butting roof' with some success, but this particular wall seems to have me baffled.

 

Also, I have occasion where the feature just doesn't seem work at all.  Does HDP care if the wall is defined as exterior or interior, and does the butting wall only need to touch the wall, cross over the exterior surface, or cover the whole thickness of the wall?  Does it care what side the butting roof comes from?

 

Last question:  I'm planning on using  6.5" SIPs for my exterior walls, but standard 4" walls with my interior walls.  I struggle with this since the ground floor wall displays at 6.5" thick on the diagrams.  Is there a best practice for this too?  I switched for a while just deciding to do an equivalent 6.5" wall below in these sections.  But that seems wasteful of space and material.

 

Thanks in advance for any pointers.

Thank you Jo_Ann.  I have a wall that has one butting roof, and one overhanging roof (one above the other).  Looking down the wall, the lower butting roof is on the left, and the higher overhanging roof is to the right.  The higher roof is actually over a patio.  The right side of the wall should be board and batton top to bottom.  The left side of the wall should be drywall below the butting roof, and board and batton above the butting roof.  So my challenge is I have different surfaces below the butting roof, and same surfaces above the butting roof.  I can't figure out how to make that happen.  It's a single story residence with vaulted ceilings from the shed roof style.

 

I hope that helps.

I know that YOU understand what you have, but maybe a pic would be a better visual display.
