Energy Heel Trusses for Hipped Roof


Recommended Posts

Image of Roof Framing Problems 4.13.21.pdfImage of Roof Framing Problems 4.13.21.pdfI can't find any way to create roof trusses with energy heels for a hipped roof. The videos and Help content talk about how to edit individual trusses and copy them but that wouldn't work very well for a hipped roof design as there are so many unique trusses. And even though I am checking the box for trusses when I auto build the roof it always builds with rafters. An image of the latest attempt is attached. Any advice would be greatly appreciated.

I've attached the "Print Image" from within Chief, not sure why it doesn't show in my message. Does it need to be a jpeg?

 

I've watched videos from Chief website, consulted the X12 Help, looked on YouTube, searched the X12 Tutorial Guide and the X12 Reference Manual. Nothing found in regards to hip roofs and raised energy heels.

Using the "Build Roof" tool, I select Trusses. (I'm fine with a framed roof but that hasn't worked with the raised heels).

Then I put 16" in the Raise Off Plate box

check the "Build Roof Planes" and then click OK

It generates a roof structure floating above the upper level ceiling.

Hi Jonathan, I assume you are aware that Chief doesn't auto-build trusses. First, make sure the roof is at the elevation that you want. 2nd, if you want to see roof framing, manually draw all your trusses. Third, build roof framing.

I have read the "Creating an Energy Heel Truss" instructions but haven't attempted that approach as it looks like it would require opening each individual truss, edit it and rebuild. I can't even get the trusses to generate so that I can open and edit them.

For more accurate help, you will need to post the plan so that myself or someone else can see what you've done, and try to help solve it.

If you have a ceiling on the 2nd floor and a roof on the 2nd floor, you should be able to create a truss on the 2nd floor.

It's a fair amount of work to create all of them. And because a truss supplier provide a truss package, I'd suggest there is little benefit to modelling all of them.

Eric, thanks for the article link. I've come across it before in my struggles. But it really is geared towards a simple gable roof rather than a hipped roof which will require me to build 50+ custom trusses with energy heels. By doing just steps 1, 2 and 3 I can generate the roof at the correct distance from the top plate and this will allow me to generate the elevations I need for my drawings. And leave it to my truss manufacturer to fill in the missing area.

 

Thank you very much for the help. Even though Chief can't generate the raised heels automatically it is very helpful to know that is the case rather than my continuing to struggle with it. Thank you to Robert as well.

No Problem.

If you really want to show truss framing in your section views, then you can do it the lazy way and only create a single truss just in front of each section camera. Then, it's not nearly as much truss editing.

This it can do. It just won't create the trusses. If you really want to create a trussed roof fast, then the transform / replicate tool and the multiple copy tool will be your best friends. You should be able to draw all the trusses for that house in about 5 minutes.

But you'll have to know how the preferred truss supplier likes to place girders and hips.  Those are key.

 

The rest is just boilerplate.

There's also the super lazy way which is to not show any trusses at all. That's my go-to!

I just let my truss manufacturer send me back their drawings which I then forward to the city so they have them on file.

 

Isn't that what everyone does?

 

Why would you want to draw roof trusses?  

 

I understand drawing rafters for a carpenter to follow on site, but manufactured roof trusses?  They even come with assembly instructions on delivery.

 

(I'm just a builder drawing his own plans, not a draftsman, so I'm curious as to what you guys do normally)

Absolutely!

Michael, 

I am also a builder who draws my own plans and I totally rely on truss manufacturer drawings. The issue I have is that my drawing elevations will not be accurate if the energy heels aren't accounted for in Chief. That +/- 16 inches of exposed exterior wall above the top plate needs to be forced into the model. Doing hipped roofs makes it (much) more complex, if I were to try to draw each truss individually. The copy feature wouldn't be able to be used more than a few times.

I'm confused with, what does actually drawing the truss have to do with raising the roof plane off the plate? You can still depict the energy heel without actually drawing all those trusses. Am I missing something?

Joey, I didn't know that Chief wouldn't generate the trusses when the box next to trusses was checked. I learned that the energy heels can be depicted by other means but it does make for some inaccurate cross sections that have to be edited.
