Why does my little closet's ceiling height change the height of the flooring over it?

[bdillard1]

I'd like to lower the height of this closet in my basement without it changing the overall height of flooring over it.  I'd like the ceiling height about 88" on the interior under the sound proofing.

One way might be to define the "Ceiling Finish" in a way that it might be built with an "Air Gap" then 2 x 4 ceiling framing 'Auto Detailed' as Insulation, then sound board below and finally drywall.

 

EDIT: and to answer your question more directly, that's how Chief works.

 

This dbx will get you to the 88" ceiling height but it's always good to wait for the smart guys to offer another method.

Two possible ways to do this:

• Change the Ceiling Finish to include an "Air Gap" and "2x4 Framing" as Larry indicated
• Add a "Ceiling Plane" at the height desired.

Either works and won't effect the floor above.

Thanks - I've updated the file - I'm doing something wrong though.  I'm trying to make the height of the little closet 88" but I must not have followed something in your explanation.   If you could take another look I would appreciate it.

Not at my computer but in the original plan the layers were all reversed with drywall on top and the remaining layers below that. Maybe those layers are the correct size as the dialog box shows but in that incorrect order? Study that dialog box again in the ceiling structure finish tab and you should get the 88" you are looking for.

 

Or try a shelf ceiling as 'help' will direct.

Thanks I'll give that a try.  

 

    I tried an failed miserably.   I got no roof this time - I've updated the plan and uploaded it.  I really think I followed your instructions but obviously not.

Thanks.  I tried doing it using this video - https://www.chiefarchitect.com/videos/watch/64/using-the-shelf-ceiling-room-structure-setting.html

I ended up getting a room that looks like something heavy got put on top of it.

 

 

 

I'm not sure what step I missed.

Double check ALL of the boxes and settings in the dialog box. The pic posted shows drywall, selected in blue, as "framing" in that little check box below the layer settings. Two things make sure the framing layer is set to fir framing as a texture/material and make sure it is also set to framing as the drywall layer is incorrectly set to.

[bdillard1]

Thanks - for hanging in there.   I promise I'm trying but maybe misunderstanding wha you are saying.   

I selected my fir framing from here.

I unchecked the boxes on the other items for framing.

I updated the plan - not sure where mine differs.

Sometimes it's best to sleep on such things....and wake up with answer....

Good morning. The video suggests that a Shelf Ceiling is the best method but Chief 'Help' actually suggests the Air Gap technique for a Dropped Ceiling but a Shelf Ceiling works in this case as well. Hope this helps. A couple plans as well.

Thank you so much, both of you!   I still have more to ask so I'll start a new thread so it doesn't become impossible to follow.
