DougDM Posted April 12, 2023 Share Posted April 12, 2023 As-Built, HIp Roof, 8' ceiling. Roof has an 18" soffit (6 on 12). They built the roof (rafters sitting on a plate on top of ceiling joists not on wall plates). We've done this many times. So how do I get CA to do this? See Section below, This is what I'm trying to replicate. i would imaging adding a second floor, remove ceiling and floor surface, etc.,etc.. How say you...Better options. I'm fine with just the cad drawing, But I would like to see it in 3D framing. Thanks, Doug Link to comment Share on other sites More sharing options...
GeneDavis Posted April 12, 2023 Share Posted April 12, 2023 Manually raise the roof, manually draw in the framing, edit to your satisfaction, take a live section view. Chief won't autoframe those two members. Link to comment Share on other sites More sharing options...
rgardner Posted April 12, 2023 Share Posted April 12, 2023 Build the 2nd floor with no flat ceiling or ceiling finish material, 1.5" ceiling height and a 2x6 floor structure without sheathing and no floor finish. Done. 2 Link to comment Share on other sites More sharing options...
GeneDavis Posted April 12, 2023 Share Posted April 12, 2023 Ryan's way is faster than mine, so proceed, but remember to set floor joists as lumber, and I think you will still have to manually draw that plate on which the rafters bear. Change the wall type for the second floor to not have an inside layer of sheetrock. Change the specs for the second floor "room" (which is the actual attic) to not have a base molding. Draw that plate using General Framing. Doing it the way I first suggested might be almost as fast, because you don't have to draw a second floor, mess with wall specs to delete the sheetrock in the "attic," or delete the base molding in the "attic." All you have to do is raise the roof and draw the edge framing, plus edit the ceiling joists. Link to comment Share on other sites More sharing options...

Done. Thanks Ryan, confirmed my thoughts exactly...now off to do it, appreciate your response. If I have time I'll post a 3D framing pic. Thanks once again.

Then I said to myself why not just treat is like a second floor (as Ryan suggests) seems to have worked. Hopefully I'll post a section and 3D framing when able. Thank you for all responses.

GeneDavis Posted April 13, 2023 Share Posted April 13, 2023 I tried framing the wall and got nothing, this, after changing the wall type by copying the default exterior wall and changing its def to read "no sheetrock in" and then framing. I'm doing it wrong and will try some more. Link to comment Share on other sites More sharing options...

It's a good idea and I've been playing with this, but I can't get the plate to show up if the ceiling ht is less than 2.6" which of course produces wall studs... At 1.5" the plate disappears: Link to comment Share on other sites More sharing options...
