Hi I would like some help interpreting the framing of the gable ends in these plans on page a3
what is throwing me off is:
The plate the gable is framed on does not line up with the plate the rafter tails sit on.
How do the 2*6 walls protruding from the gable wall fit in and also the diagonal braces that attach to them.
Without those it would be easy, I apreciate any help on reading this.
Built from locally sawn hemlock, this functional outdoor feature uses structural screws and metal connectors for fast, sturdy construction.

They don't protrude
I think what your seeing is the standouts for the eaves.
The diagonals make things more ridgid.

Those shortwalls are built to different heights depending on the side being framed.
?? What 'plate' are you referring to? What 2x6 walls 'protruding' from the gable wall? You don't tell us which section view you are referring to. This looks normal to me. Gable end wall, eaves, barge rafter.
FYI ... looks like your elevations are wrong. The narrow gable fall short of the main gable roof peak in the one drawing, but looks almost dead even in the other. You do have two different roof slopes, right? (these should be clearly indicated on the elevations and maybe the sections).

He's suggested looking at A-3
In the elevations and on the framing plan, the ridges are clearly at different heights. The rafters bear on a series of short walls framed on top of the 2nd floor platform, those are at different hts also. The angle braces and simpson brackets are meant to hold it all together, with the high collar ties that make up the ceiling joists I guess. Must work if it passes engineering and inspection.
At least that's the way I"m seeing it.
I did look at A3. I don't think this is unusual at all. Possible problem, though ... with the rafters "bearing" on the intermediate short walls ... as I'm guessing they aren't intended to be bearing walls. Not sure that I would notch the rafterson a non bearing wall. But I'm not a framing guru, either. The ridge board is also not structural (again, assuming), so not sure how that is to work. Needs a framing plan.
The elevations only show "clearly" the different heights in the end elevations; the front shows them 'almost' the same. I think it appears inconsistent.

Looks like I double posted ... don't know how to delete a comment.
I didn't have much trouble seeing the difference in elevations in all of the views -- it does require sort of a double-take, but that's not unusual in any sort of "see-through" projection.
But I agree the ridge did seem a bit light for essentially un-stayed rafters (the collar ties look to be insufficient to prevent spread).
As you say, this is far from a framing plan -- it's more of a conceptual drawing, from a framing standpoint. The devil is in the details.
The gable ends need to use a "dropped" design. Eg: http://www.ebuild.com/products/imageGallery.hwx/Q/productId.322376
BTW ... you really don't have a framing plan. You do have a building section showing framing, though.
gable framing
I agree it's kind of weird. As someone else all ready pointed out, you need a framing page. I think you are asking why there is a plate break in the gable end walls or said another way, why is there a two foot wall under one gable and 2 foot six under the other? Seeing as this roof is all valleys why would you not build the gable wall with out the cripple wall as no rafters are sitting on the walls, they all run from ridge beam to valley.
It is interesting that the elevations called out would work for the different pitches of roofs to meet at the soffit line, but again seems like the crip wall should go away with the added bonus that you shouldn't need all that bracing if the wall was 'balloon' framed from the plates on the floor to the rafter height. Maybe I'm missing something?
