the HD vid's could be good to watch

 

as the HD products (except PRO) can only do auto-roofs

 

there are 24+ roof styles that can be done with the auto-roofs

 

my intermediate Chief instructor claimed that "any" roof could be done auto

 

CA recommends starting with auto then switch to manual if needed

well, I don't have roof skills

 

but he did show us an insane asylum circa 1890's with a massive set of roofs and turrets etc etc etc

and it was all done with auto roofs

 

if you check CA's tutorials 24+ roof styles can be done via auto-roofs

some of them fairly complicated

 

I would never say that any roof can be auto only

 

but I think auto-roofs are discredited too much

I start with auto roofs and go manual as needed.  Crickets for me are always manual.  I set up lots of my roof planes with the wall dbx > roof tab.  For energy heels, I have created a cheat sheet for the various roof member dimensions and roof pitches (to get the "vertical rafter depths"), then it is easy to figure out how much I need to raise the roof to get it where I want it.  Once a roof is built and needs some editing, I open up a 3D full overview and put it on my 2nd monitor so I can watch and see how things are snapping together.  Any more, lots of editing can be done right in the 3D view as opposed to working in plan views. 

 

When I 1st started with Chief (v7), I was a little intimidated by roofs.  A training session with Mont Stephenson at CA's office in Cd'A broke the ice for me and other than a few specialty roofs (turrets, etc.), I have been able to conquer all the roofs required for my projects.  Practice and experimentation and paying attention to how changes in the dbx settings affect a roof plane are key to understanding how Chief roof's work and behave.  There are still a few things that aren't perfect with Chief roofs and/or roof framing, but generally, it is possible to do almost everything needed ... at least for the jobs I have worked on this is the case.

Would you be willing to share your cheat sheet? I am just starting to use Chief as my main drafting program and doing the roof structure for our area is one of my main problems. Energy heels are a must when it is -32 C.

Here's the cheat sheet ... nothing too fancy at this point ... someday I may put it into a spreadsheet so it looks pretty.

In the event you don't know how to use this information for energy heels, here's a little more information that will help you.  If you already have this figured out, maybe it will help someone else.

In this example, my truss has 2x4 top and bottom chords.  The roof is 6:12 pitch.  The vertical rafter depth for a 2x4 is 3-15/16" (per the roof plane spec dbx and as shown on my cheat sheet).  In the Build Roof Specification dbx I have shown that I need to raise the truss top chord 8-1/16" to give me the desired 12" total energy heel height at the outside edge of the wall. 

 

It is up to the designer/architect to determine what energy heel height is appropriate/required for a given project.  For climate zones requiring lots of heating, an energy heel is often necessary to achieve a full depth of ceiling insulation at the roof-wall connections.  Obviously there are many ways to insulate a ceiling/roof so roof design (including a requirement for energy heels) is driven by the overall building design needs.

Hi hope you don't mind Curt I took the liberty of making a Word Doc/PDF out of your info for myself but I figured others might be able to use it too , (cheat sheet and images) so here it is

 

Curt's Energy Heel Info.pdf

 

This KB Tutorial came out in Nov. too Sherry

Thanks everyone for all the info. It will be a great help as I go through the pain of changing over to Chief. My first project is well on its way and no major bumps so far. All the training videos have helped tremendously.
