If I take the above plan and build the roof with "raises from ceiling height" 24" above ceiling, it works, but 12" does not. Expand Strangely enough, this seems to be the key right here. I just started a new project with raised heel scissor trusses and decided I'd try setting the roof envelope up for 14" truss heels. No issues with the wall framing, it behaved just as I would expect it to! Whether I pulled the ceiling plane out to the exterior of the wall framing or left it at the interior made no difference, it worked either way. So then I figured I'd try and back the roof envelope down to a 12" raised heel and bang, my wall framing shot up to the roof baseline. And doing that really seemed to mess with the software, because after that the formula of "Desired Heel Height - Vertical Structure Depth = Raise Off Plate" amount no longer produced the roof baseline where you'd expect it to be. The wall framing would behave like it's supposed to once the heel height changes from 12", but the math no longer worked for the heel height. Eventually I got the heel height back to within 1/16" of 14" by zeroing the ROP out and starting over. So yeah, something weird going on with the software with regards to 12" heel heights with sloped ceilings, but knowing this is going to save me a lot of frustration going forward. Should probably be using 14-16" energy heels anyway. Link to comment Share on other sites More sharing options...
SHCanada2 Posted February 22, 2023 Share Posted February 22, 2023 if I remember correctly I raised a similar issue a couple years ago, where attic walls will appear only above a certain VSD and/or pitch Link to comment Share on other sites More sharing options...
tundra_dweller Posted February 22, 2023 Author Share Posted February 22, 2023 I can confirm that the behavior is the same in X15 beta, although the new "Heel Height" feature in the roof DBX seems to work very slick, thanks Chief! Link to comment Share on other sites More sharing options...
GeneDavis Posted February 23, 2023 Share Posted February 23, 2023 Does Chief acknowledge the bug? Link to comment Share on other sites More sharing options...
tundra_dweller Posted February 23, 2023 Author Share Posted February 23, 2023 Up until today I still wasn't sure that the problem wasn't just me missing something. I'll take a look at the process for submitting a bug to Chief and do it, unless someone else wants to or already has. Link to comment Share on other sites More sharing options...
SHCanada2 Posted February 23, 2023 Share Posted February 23, 2023 i looked and i did not log the original attic wall issue with support. Link to comment Share on other sites More sharing options...
tundra_dweller Posted February 23, 2023 Author Share Posted February 23, 2023 I have submitted this to tech support, will post updates in this thread. Link to comment Share on other sites More sharing options...
tundra_dweller Posted February 28, 2023 Author Share Posted February 28, 2023 Just to follow up, tech support did not find a solution for this case. They recommend framing the walls with a flat ceiling, selecting "Retain Wall Framing", unchecking "Flat Ceiling Over Room", then build your trusses. There may be a possible fix in a future release.
