GMennie Posted May 13, 2017 Share Posted May 13, 2017 We generally build with bottom chord bearing roof trusses, where the bottom chord extends out over the bearing wall, creating a level, flat soffit. It seems Chief defaults to a top chord bearing truss, where the top chord runs past the bearing wall creating a raked or sloped soffit. I've attached a picture showing the sloped soffit to help clarify, along with the flat soffit picture I am trying to replicate in Chief. There's got to be an easy way to change this, but I can't seem to find it. Appreciate any help! Thank you Link to comment Share on other sites More sharing options...
Chopsaw Posted May 13, 2017 Share Posted May 13, 2017 To generate a flat soffit just be sure "soffits" are selected in the Structure tab of your Roof dialogue and also on the Options tab select "Boxed Eave:" Link to comment Share on other sites More sharing options...
GMennie Posted May 14, 2017 Author Share Posted May 14, 2017 thank you both, I think the 10" guess, after some quick math and a diagram was pretty dang accurate....almost exact for my 2 foot soffits. Now I've got it! Thanks again both! Link to comment Share on other sites More sharing options...

Now I've got it! Thanks again both! Dont try and calculate, or you will have to calculate for each and every pitch. It's a futile approach. Also there is no rhyme or reason to that calculation. 1) as was mentioned check "trusses" checkbox. 2) know what your top plate absolute value is for the wall your roof sits on. 3) in your roof dialogue box, lock your pitch and set your "top of fascia height" accordingly. (Of course know your fascia height in advance from the roof structure tab) This is the most reliable way to ensure your trusses will sit on your top plate as they do up here in the north east, which is where I'm assuming you are from as well. This will give you a flat soffit. Also this will ensure you pick up the right elevation point when you do your storypole elevations etc... I think the programmers of roofs in Chief all came from sunny California hence the default and useless rake system. Looks cute though. Link to comment Share on other sites More sharing options...
