Alaskan_Son Posted March 26, 2020 Share Posted March 26, 2020 Yes. It's being measured as Levis shows. The baseline is the other way. Its a gable end which has no baseline of it's own from which to measure for that Upper Pitch. Link to comment Share on other sites More sharing options...

Expand Weird cos there is a Baseline for that Plane out at the Fascia , which I assumed was the one it was using for the measurement. I wasn't sure why 3 different versions all calculated it differently though , but your explanation would solve that I think, as I didn't use the same house (width X length) in each version, I just drew a random box.

Expand Although I do think it makes sense as it works, I can also agree that the information in the Help files on this particular roof style is oddly generic and pretty minimal.

Expand I would've probably experienced the same hang-up. Not intuitive. It would help make it more clear by labeling it "In from baselines" or "In from each side baseline"... but even better why not just ask how wide you want that upper hip to be?

It can only use one (and I think it just uses the highest of the 2). On 3/27/2020 at 5:11 AM, DzinEye said: why not just ask how wide you want that upper hip to be?

Why not just be consistent and use same In From Baseline? Expand Because of the ambiguity/confusion which Mick just highlighted. If it asked for width of hip there would be no ambiguity. When you suggest 'in from baseline' is consistent... what is it consistent with? If you are using 'in from baseline for a pitch change on a roof plane, then yes it makes sense, because you're working on the plane with the baseline it's measuring from. I understand that once you learn such nuances it's no longer an issue, and everyone who's gotten used to the 'way things are' doesn't want to see anything change, but in the long run, my opinion is that it's always best to make software as intuitive as possible.

Kbird1 Posted March 28, 2020 Share Posted March 28, 2020 Okay, I just could let this go yet as it's annoyingly WRONG, ..... how Chief is doing this..... at least from the point of view of This Builder/Master Carpenter and perhaps I am once again " missing something " with my conclusions....... but.... and not picking on anyone but to illustrate some points made....... and from some observations from a basic 40'x30' Gabled Box home with a 10/12 pitch....

Its a gable end which has no baseline of it's own from which to measure for that Upper Pitch. Expand A Gable Wall in Chief doesn't have a Baseline (BL) , no, so why is Chief Using it as a basis for the so called Upper Pitch? a Roof Plane always has a BL, both in Chief and the Real World (RW) but it's NOT an Upper Pitch ..... it is a Hip Roof Plane, building off a different Wall Plate Height (the Seat Cut of the Birdsmouth Height.) this is the Height Chief should be using to calculate the "Cut" point IMHO. The fact it is not an Upper Pitch is shown in Chief's own DBX's ie the Roof Rafter Pitch is 0/12 , even though it displays at the "given pitch" on Cross Section ( 6/12 below ), a Cross Section through the Main Roof Plane and 1/2 hip confirms this... ie it shows the Half Hip roof plane is parallel to the ground or 0° (or 180°). .

Expand Chief CHEATS and calls it an Upper Pitch , when it isn't really, personally I have never seen it calculate the way they do it, and from Framing it in my Test Plan, it is not cutting Birdsmouths (BM) on the 1/2 Hip Rafters thus they are ALL too high (I assume) or the Wall is Framing at the wrong Height?. The Rafters weren't "Trimming to Soffit" either at 1st, until I lowered them down (the measured ( 2 3/4") BM Depth), then something "clicked" in the "auto roof framing tool" and they were okay.

Expand It's not a Consistent use of the Term, the Setting doesn't even work the same way as it does, for example on Gambrel or Mansard or Gullwing Roofs. I think someone just found a way to use "Existing Code" ( and DBX) to Fudge it, and not to document this total change in behavior ( ie consistency of the term "in from baseline" ) somewhere is just wrong and unhelpful for all Users trying to figure this out. Levis' pic (above) or similar and a short explanation in the Ref. Manual on how Chief "does it" would of sufficed for one and all. And back on Topic ( ...sorry Dave), his way in the last few minutes of the Video, may actually be easier if your Architect was kind enough to give you the Fascia Height. // Rant Off //...... and yes I do feel better M.

Expand 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. On 3/28/2020 at 11:26 PM, Kbird1 said: The fact it is not an Upper Pitch is shown in Chief's own DBX's Expand 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. On 3/28/2020 at 11:26 PM, Kbird1 said: Levis' pic (above) or similar and a short explanation in the Ref.

Go ahead and request it. That would be great. Expand 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 ) .

Expand 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..... M. Link to comment Share on other sites More sharing options...
