# How to generate a flat soffit??

## Recommended Posts

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

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:"

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!

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.

• Hi Chiefers,

I am having a weird issue where the roof framing is being generated out of place. It is also ignoring the option to "Trim Framing To Soffits" option and extending the "I Joist" rafters outside of the walls. I have tried all sorts of things to get this fixed and I cant figure it out. Any suggestions?

I attached 3 images of the issue and a copy of the top floor / roof in a separate file (original complete file is HUGE)

I have noticed something strange.  Well strange to me, maybe it makes sense but I can't see why.  I want to make a cathedral ceiling,  The eave facia is deeper than the gable fascia and when I look at an overall view this is what I see.  Is there an easy fix for this?  The attached file is just an experimental file that I was using to learn how to control roof and soffit features.  Also to get roof framing to behave without excessive thinning.

• Hey ChiefTalk, how's everyone doing?

I'm trying to make a 7' tall frameless shower with a partial ponywall on one side and a curb under the rest, as shown in the attached picture.

I've successfully created what I want with two different methods:
1. Creating glass slab half walls at my desired height, then using soffits to create the ponywall and curb under the glass wall
2. Using a pony wall, where the bottom half is the 6" tall curb and the top half is my 7' tall glass wall

However, anytime I try to paint a new material onto the soffits (the correct tile finish), the glass wall cuts off half of the soffit, both on the curb and the ponywall (shown in second picture).

Why would the material painter screw up my soffits? It’s not changing anything structurally, just the appearance of the soffits (Right?). I've been instructed both by the reference manual and other users on this forum to use soffits to create simplistic surfaces like this shower curb, so I'm a bit vexed.

p.s. While we’re at it, if anyone has a suggestion for a better way to create a frameless glass shower like this, I’m all ears. This is simply the way that I figured out how to do it myself.

Thanks!

• Hi all,

This dotted line (highlighted yellow) has been appearing on a few projects that I am working on. I can't seem to get rid of it or even click it! Not sure if it is part of the roof but it is not the depth of the eave so really not sure what it is showing! It seems to follow the roof line but not always...your help would be much appreciated!

Thanks,
Rebecca.

This has to have been discussed in length somewhere, but I couldn't find anything. I've got this problem on every plan, so it's either the program or my roof settings. The soffit won't miter accurately. There's alway a small wedge sticking out where a boxed gable soffit meets a boxed eave soffit.
