Astrigal Posted April 9 Share Posted April 9 Can CAx15 allow somehow for a raised, or boxed up ceiling into a floor truss? I have tried buy the error message said it wasn't allowed. We get the truss manufacturer to make them this way for our homes. Link to comment Share on other sites More sharing options...
winterdd Posted April 9 Share Posted April 9 Curious about this as well. Even if the truss company can build to suit the trey ceiling will it be as strong? I have a request to do this in a two story home right now. Link to comment Share on other sites More sharing options...
joey_martin Posted April 9 Share Posted April 9 I know that those can be built into roof/ceiling trusses, but not sure I have seen them in floor trusses. The Tray ceiling tool within Chief won't build a tray into a floor platform though as far as I know, be it truss or conventional lumber. Link to comment Share on other sites More sharing options...
Astrigal Posted April 9 Author Share Posted April 9 Can you fellas think of any creative way to get a tray ceiling into a floor truss? I do this all the time with great rooms. (now where's the cross my fingers emoji?) Link to comment Share on other sites More sharing options...

(now where's the cross my fingers emoji?) We do it around here once in a while too. Make a room divider wall directly above the tray ceiling room below and adjust the floor & ceiling measurements. Then build three individual floor joists (and line them up), install a crown mldg to hide the gap. The cross section looks almost like the real thing.

Astrigal Posted April 10 Author Share Posted April 10 @ValleyGuyThat's an excellent solution. Thank you! I sure wish CA would incorporate a tray ceiling option into a floor truss. That way the cross sections would be more accurate to the way residential builders actually build here. Link to comment Share on other sites More sharing options...

You can edit the polyline of a roof truss. This is all manual, so it's not something worth doing until the very final steps of your plan set, but it makes for a nice looking truss. Tip: Your floor trusses will look more realistic by adjusting the web spacing to somewhere between 48" and 55". Most floor trusses have a bottom chord span of about 48" and a vertical post to reduce the top chord span to about 24". Chief doesn't model floor trusses correctly, but they build nice when using a roof truss. Unfortunate... Link to comment Share on other sites More sharing options...

para-CAD Posted April 14 Share Posted April 14 Cheaper to set the regular floor truss high and furr down around the outside to create the boxed effect. 3 1 Link to comment Share on other sites More sharing options...

Yes I agree, and not only that but the structural integrity of the floor truss framing member remains intact with a full span and depth and with proper supports at each end. You could just increase the floor to ceiling height if need be to accommodate the trey ceiling ? Link to comment Share on other sites More sharing options...
para-CAD Posted April 14 Share Posted April 14 Lot's of big homes in the south have 10' first floor, 9' second. Furr downs are used quite often to make custom ceilings. 1 Link to comment Share on other sites More sharing options...
Astrigal Posted May 4 Author Share Posted May 4 @para-CAD I would do as you suggest... make the truss shallow and fur down, but then the exterior plate heights have to go up and vary room to room and the carpenters like it when all the plates are the same height so it's easier for them in the field.

mthd97 Posted May 5 Share Posted May 5 Good carpenters will always read and follow the plans you create and that are also certified by a structural engineer. @Astrigalyou are in charge of the design not the carpenters. If everybody tried to make a carpenters job easy we would let them draw the plans as well. Link to comment Share on other sites More sharing options...
