It looks like he was never looking for a "Rim" but a joist set along the edge of the ceiling for backing. Do you know how to get a joist there auto?

There's a "Framing Reference" that Chief has to set up framing in a specific manner but WILL NOT allow a ceiling joist in the location you are looking for. Does seem a bit strange but manually adding a ceiling joist is probably the only way to have Chief frame it the way you want, and in my mind "correctly" as well.

Is it possible you've raised the roof creating the taller attic space Joey's referring to? Instead of a second floor? That's the only way I can get a section to look like the one you've posted. I don't know how to define a 'room' like Joey's suggesting on the attic floor but maybe I'm missing something?

Not sure what you're expecting but a 'Rim Joist' typically doesn't create "backing for the drywall."

Is the Framing, Rim Joist Layer turned on? It doesn't show in your Active Layer Display pic that you posted? EDIT: I see that you have 'all layers' turned on please ignore this comment.

Hey Joe, Here's a pretty long winded video hoping to give you an idea or 2 for your template plan and saved section cameras.

This typically happens if Auto Build Roof has been turned off and then the ceiling heights are raised. The roof stay the same height and ceiling is raised leaving those angles at the outside walls. Of course this can also be done intentionally and is the method if that's the look you are after.

That box was checked in every version of every plan and changes nothing to get you what you were looking for, but if it helps it helps.

I think he wants a 'shelf ceiling' at 88" high for both the walls and ceiling.

For some reason that basement floor won't draw shelf ceilings as expected. I went to the first floor and changed the master closet to a shelf and it worked fine. Dunno much else.

If I open a new plan and draw in a small 'closet' and define as shelf ceiling it works as expected by dropping both the ceiling and the walls. In this plan, not so much. The closet that is drawn is actually an island room as the wall against the foundation wall does not connect but not sure what effect if any that might have. Also in the build wall dbx automatic balloon framing is turned on but doesn't change when turned off. Time to wait for the smart guys again.

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. https://www.dropbox.com/s/vdxci23yo8umk0e/Nutella3rdD23e (1)C.plan?dl=0 https://www.dropbox.com/s/ogizhxoyfx7z2ie/Nutella3rdD23e (1) (B.plan?dl=0

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

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.

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.

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.

Looks good Doug and I never bother to try and build that in Chief and just throw a detail at it in plan view, not worth the effort in my world. What do you think of the OP's challenge after seeing his picture above?

Yeah, the details matter and in this case defining "a lot of overengineering" might be good next step. Definitely possible, and conventionally framing that new roof is the way to go but as far as getting Chief to (from the OP) "show the exact truss / roof framing that my builder can use." Not going to happen without the needed engineering unless your builder likes to wing it without engineering, permits and inspections. You can however show in Chief an approximate framing possibility that the builder and engineer can then size members etc. and then build. Just shape the roofs in a way that allows for that 7 ft. passageway and let Chief auto frame the roofs.

Yes, the video was only intended to show a technique and not any specific construction detail. Do you build in a similar manner in Canada?

Not exactly sure what you are asking but this might help. 199498449_DOUBLEGABLE.plan

Chief will sometimes remember wall locations from previous floors and previous builds of the plan. Try saving as and shutting down Chief and reopening the plan.

If you do decide to customize your tool bars make sure you have a backup of your toolbar file because Chief can get pretty creative with them.

That behavior has made me crazy for years. Sometimes I'll hold the control key and eyeball the next placement but really have no less clunky a method. I've also places them by hand and used the align distribute tool but like I wrote no less clunky.

...and of course the ever reliable..
