Whether you agree with the logic and approach or not, I'm sure the reason is because they wanted to re-use the code and dialog box.  I would do the same thing if it seemed logical to me.  I think that's where the core of our disagreements lie (whether between you and I, you and Chief, me and Chief, etc.).  Chief chose to use the baseline of the perpendicular roof plane.  I see nothing wrong with this. Yes, I can see the benefit of using a different parameter such as width at wall.  Go ahead and request it.  That would be great.

 

Wall width doesn't really work either but is an alternative I guess and better than the current method..... as with the other person who asked me recently , normally you just want to know the distance in from the gable wall the pitch change starts at the ridge Level , eg in their case they were try to get chief to start the pitch down 11ft from the gable wall. It's also one of the easier ways to do it Onsite , measure in from gable wall, ( baseline) lop off the ridge you previously ran long, and offer up the precut Common Rafter ( you made using known pitch + run ) .  All assuming the Truss company hasn't already done it differently :)

I think you're grasping at straws with this one.  Sure if you measure it from that direction there's no pitch, but its easy enough to understand that its pitched and its also an upper plane.  We can use at least a very small amount of deductive reasoning there.

 

Not at all it isn't an Upper Pitch, as Noted above, no matter if Chief wants to call it that to make there Code and DBX work.

True, but the more we can use auto settings, the better. 

 

Oh I am all for that , and I am sure with your level of Skill  n Chief you can make Chief's way work to get that cut point exactly at 11ft from the Gable Wall , but it's obvious that everyday Users can't ,ESPECIALLY when then have no clue how Chief is really calculating the Pitch Change Point.

 

Enough from me , I just needed to play with it for my own learning but still see no easier way to do what is normally wanted.....

It's Never the Architect's Fault , most of you put that right on every single page off the Plan Set :) ..... just joking , I didn't mean it quite like you took it I think, I've just seen a lot of PDF Plan-sets lately that are very poorly dimensioned, apparently AutoCAD mustn't have an Auto Exterior Dimension Tool bad :o .

Of course I knew you were just having a dig, but you're right...architects do put a lot of that kind of language on the drawings... I definitely have both you posted on all my drawings! :)

This kind of surprises me.  I wouldn't think this is how you'd build a full hip?... so why a partial?  I understand though, you're looking at Chief from the perspective of building it, but first it has to be designed, and from the design point of view, I'm looking at it from how wide would I want that section of hip to be in relation to the overall width of roof and roof pitch.  Once the look is established I can call out on the plans the plate height and width for that section of roof... wouldn't that be just what you need to frame it?

Completely subjective.  It could be just as easy to start from the bottom using the Height (Starts AT Height) or from the heel (In From Baseline).  I've framed houses for many years, and I honestly don't believe I would ever use that top number you're talking about as my main point of reference.

Is it a lower pitch?

Why not? I'm sure there are 10 different ways to frame it depending on the circumstance's but standing the ridge with the common rafters either side and then one off the end of the ridge is pretty common...

 

Your just looking at it from the other direction ( so to speak )  but at the moment we don't have either method to use , as Chief has made up it own way of doing and calculating it.

 

And yes the Plate height would work too , only chief is NOT placing the plate at the correct height currently either.....

It is simply a Hip roof built off a different plate height than the Main Roof Planes, it is not an Upper Pitch as the Term denotes it in Chief eg for a gullwing Roof.

IMHO of course, we obviously have a difference of Opinion on that....

ie in from the Gable Wall as I said...  whether you go in and then up (Rise to find the Point or in and then down at the pitch angle from the ridge is all the same thing, eg when laid out on the Plywood Floor for example to find the Plate Height for the Gable wall you'd like to frame before standing it.  ( or draw CAD lines in Chief at scale to do it beforehand.

 

We all do things differently depending on experience/skillset etc but in the end the Result is the same ...hopefully.... 

 

There is no way at the moment to use a known Onsite method ( to me) in Chief to get the same result and the fact Chief does not document,

their Method at all just makes it that much more frustrating, in the Video She actually skips over the whole in from baseline "thing" and choses

an arbitrary 10ft in from BL. In the Other videos She actually goes in to BL and explains it and explains what the BL is and where it's located

in Chief etc, the Info, in the case of a Half Hip has no correlation if you have watched the other short Auto Roof Build Videos in the series.

Yep, I saw that in your section.  That should be fixed.
