Is there a better way to align roof with varying ceiling heights?

[John_Charles]

Hello

 

I'm revisiting an old drawing project that kicked my butt some years ago in Chief regarding the ceilings and roof alignment by simplifying the roof style (have some time between projects so just trying to do some practice/learning).....

 

Have discovered through searching years old posts that the roof alignment issue over a split level single story I was struggling with was best resolved by drawing the plan and lowering the floor level (that wasn't obvious to me at thetime but glad I know it now).  I originally drew the plan and raised the floor level for everything except the garage and ended up with so many wall issues on a skilion roof structure it was horrendous...

 

Which brings me to my question here...

 

As Chief sets roof heights from ceiling heights, can anyone tell me the simple way you work around or where to find info on stopping the ceiling height affecting your roof, when you have adjoining rooms that have differing ceiling heights?

 

I've attached my query in the form of a screenshot of a sample room with the main ceiling set at 140" and the smaller room at 100" as an example.  It creates the wall issue and obviously the roof line.

 

I had previously tried to keep the ceiling heights all the same and then just draw a manual ceiling plane but that became unwieldy when it came to framing, and pony walls/2nd story attempts gave rise to other issues with alignment.

 

Does anyone have a better solution/suggest a simpler way?

 

Thanks

If you want a consistent roof height....

• Modify the room ceiling heights by specifying the room "Ceiling Finish":
  • Air Gap (space below Floor Joists, Rafters or Trusses)
  • Framing (2x4's or 2x6's)
  • 1/2" Drywall

That will create a flat ceiling below the framing above the room.

Would you mind showing me a shot of the dbx doing that?

I have attached the sample model here...

 

I'm not sure what I'm missing here....can anyone help?

 

Thank you

what do you want the roof to look like? Normally I will raise the roof or alter the existing roof to go over another part of a building

I just want to raise the roof height to match the surrounding structure without losing the ceiling height of he smaller room.  I've tried to do this with a ceiling plane as a work around but am wanting a simple way to do it so that framing is correct....

I would disconnect the small room walls, build the roof, turn off auto roofs and reconnect the small room walls.  Set the ceiling height you want and it will remain.

 

When I have situations like this, it's better to model the roof first and turn off auto roofs.  Chief is pretty insistent about matching floor and ceiling heights.  Get as far as you can and turn auto generation off.

select the roof planes and go to transform replicate, move it in the z direction

Here's an example of the dialog box that Joe mentioned in his reply. Essentially you're setting the rough ceiling height at the tall height (140.5") but then adding layers (framing, air gap, etc.) to the Ceiling Finish area to push it down 40" to match the ceiling height of the rest of the plan. Hope that helps answer your question!
