Guys, you nailed it. Glenn, wall is thick, and that is really a problem for me for quite some time now. Clients all go for fashionable green design and responsibly ask for energy efficiency, but when they have to pay for 11-12" thick r-45 wall with total of something like 14.000 sq.ft of 2" polyiso, they go ballistic. I can't help it. Double wall is great idea, this could solve lot of problems with "roof cuts wall at the bottom". -I am aware that (still) we can't expect really accurate details, and all of this is even worse headache when you take a look at roof detail with all layers that I can't possibly add to Chief's roof, like in detail.jpg. I don't know why is this such a big problem for Cheif, I expected that to be solved in x7. Importance of roof layers is equal or greater than wall layers. So, making details in AutoCAD is still a necessity. CJSpud, house should be build on Kopaonik ski resort, and that is the problem - it is pretty south, but high, and snow constantly melts and half-melts and turns into ice and falls again, so estimated snow load is close to 90 psf. Wind is 90(130 gusts), from every possible direction, but this is lesser problem, because house will be sheltered in small valley. Problem with snow is that house will be energy-efficient, and roof thermal envelope criteria is r-75, so it will not melt. Building set is finished and delivered long ago, but this is my clients newest inspiration. Anyway, by manufacturers tables roof rafters should be 14"x1-3/4", LSL, floor joists are 14" I-joist below 7/8" plywood. On top of that are all radiant heating concrete slab and other layers. Just wonderful. Span between posts is rougly 16', and, between two beams 12' - check SECOND-FLOOR-PLAN.JPG -Roof ridge is constructional ridge beam, rested on LVL posts placed in walls. Frankly, I still havent solved the problem that Monitor roof would have to cut this ridge beam, I am making some sketches, but I don't like that whole story. I will probably have to leave continuous ridge beam visible, or to place short lateral beams between doubled rafters, to support 2 new end posts or to advise client to forget it. -Unfortunately, since I am an Licensed Engineer of Architecture, this is not my first calculation. This is also my biggest problem - I will not supervise this construction (it's just too far away, and we couldn't agree about the price), but, legally, I am responsible anyway, even if some unidentified guy on site doesn't follow my plans and specs, I have to prove that in Society of Engineers, or end up toasted. 16" LSL beam will do more than enough, so, I will put 18". Anyway, people say that after a first inch, all other doesn't matter. Posts are only 5-1/2"x5-1/2", but laterally supported by both wall frames and perpendicular beam on half-height, to avoid deflection. On second floor plan you can't see the right post, because this is not a constructional drawing - post is hidden in corner of fireplace framing and covered by stone screen. I just didn't wont to bother you with stuff outside this monitor problem. -2x10 appeared out of nowhere, Glennw found out what to heck is that, sub fascia, and that will be gone. I tried to upload plan file, but, since this is my first contact with Chief Architect (friend from Buffalo N.Y. left his oversized IMac at my place, and went to cruise Europe), my first file is modest 447 MB, zipped 355MB (never ever import stuff from Sketchup), so, this tortured IMac stammers so much that I can hardly work, living room rendering took 9 hours for 12 passes. Next time I should reduce playing with furniture, coffee cups and stuff, but, after 20 years with AutoCAD and 3DSMax, I just had to try playing with it. And I must say that, in spite of all the problems, I like it a lot. But I will never start new project on unknown software again. Anyway, thank You Guy for showing interest. I couldn't find too much stuff on net about Chief and Monitor roofs.

Thank you guys, it's easy when I can call you to help... During 3rd year of studies, I took a special course in Traditional Wooden Constructions and Carpentry, and it is really hard to switch from 6x18 to 1.5x5.5. Everything looks like toothpicks. DJP, thank You for advice. DSH, Fascia planes just came out of nowhere. They don't show in Perspective framing overview. I guess that they are automatically placed for upper rafters blocking. So far I decided to solve this main issue, and fascia - well, I can just reduce it to 0" thickness, if nothing else works. Anyway I have exposed rafters in real plan, so I don't need them. My basic problem is that I am constantly trying to do strange plans by the book, and that usually doesn't work... I will have to go around by your approach. By the way, monitor roof should be placed above this smaller (living room) roof.

Thank you, Dave, I just have to continue to dig through this a little more. Some things are not looking as I would like them to look. On this project I will just plot the plan set and send it 300 miles away, and like 1800 feet up. So, some guys that I don't know will frame blindly by my drawings. So, I am slightly restless... Whenever I try to do something elegantly and by the rules, and not to cheat, it turns to nightmare... Look like I am not made for rules

Hi Guys, I am struggling with this problem whole day, and just can’t move forward. This is the problem: -I have monitor roof above cathedral ceiling room. File is attached. I solved general layout by adding 2nd floor, with roof cuts exterior walls at bottom. So, it looks good, but when it comes to framing, stuff hits the fan. I need framing to be perfectly accurate, or materials list, wall framing elevations, and everything else will go to town. Also, I can’t allow any risks with framing, because this will be built in high wind and heavy snow area. Solution is to place really strong beam, like 5.5” by 12” or 18” below 2nd floor interior walls, and rest those on posts placed in Ist. floor exterior wall frame (Attached file shows some insane y axis spans, never mind those, this is not a actual project, but small mockup ). First floor roof will rest also on those beams using typ. Strongtie hangers, as should look (roughly) on section1.jpg. Problem is in manual framing – I need to position beam below 2nd floor wall. Since this is cathedral ceiling, I have to uncheck “ceiling over this room ”, so I have hard time placing ceiling beam (or unidentified framing member) exactly on elevation that I need, because it is not pushing up monitor exterior wall. But what I get is section2.jpg - clearly, beam is too low, and this stuff cannot be connected. Roof cuts wall at the bottom, but bottom is too low. I can move this “framing member”, as high as I want, but monitor wall will show incorrect framing – bottom plate will just overlap with beam, and, also, beam will show through the roof laterally left and right from monitor part of roof… What I need is to move entire structure that “grows” above beam up, so wall frame rests on beam and roof rafters can be attached to that same beam, as in section1.jpg. If you pay attention to Persp. Framing overview with Vector view, you can see that bottom plate of the upper walls is like 9” below top of beam. At this moment I am wondering that maybe only solution is to place "framing member" totally below roof rafter, without cutting rafter lower edge, but another problem is how to set wall to extend down enough to rest on beam... This is actually the same problem, just reversed - setting elevation of bottom plate... Any ideas? monitor 1.zip

I will listen to you advice. Problem is that somewhere 3 days ago I lost patience and started messing with roofs big-time, editing wall by brutal force, and I have to clear all of that. This story -and-a-half has killed entire CA logic - second floor is only like 5ft. tall, and "ceiling over this room option is checked out, so, I will play, just to see what happens.

Hey dshall, you pronounce really good. Looks like you had been practicing over that mp3 file. I was following some baseball on sport channel, but I just can't figure out. Maybe you should make a vid . However, Football makes much more sense to me. I am surprised that you are following soccer, feel welcome to join me and the crowd in sport cafe, over World Cup greased with beer and grill... I learned a lot from part 3, mostly that you are one persistent... This stuff took a loads of patience and determination. I am still slightly concerned with framing inconsistency between left and right side, I will redraw entire stuff all over again from scratch and experiment a little. Awesome job this roof stuff.

dshall, Boxon is nickname derived from Bojan Jovanovich, M.Sc.Arch. I even attached MP3 with pronouncing. I will have to work a little on my profile . And big image below is Belgrade. His_masters_voice.mp3

dshall, this was ingenious. You cooked it better than Jamie Oliver. I just wonder, I have one and the half floor, and second floor is only if I remember correctly 54" (half of a 9' precut stud), how will that effect this whole story, I have to cook this over weekend. Only problem is that you slightly misspelled my nick ... Thanks a lot, man.

Hi everybody, This is probably common problem, but I couldn't find anything similar in search. So: -I am trying to make gable wall between two abutting roofs, but above opened loft, where I don't have any walls below. In real life, wall infill would be placed on constructional ridge beams and multiplied rafters, leaving me with only one visible post, that would be incorporated in kitchen island below. So, what I need is a inverted "V" shaped exterior wall, placed only above living room gable wall with cathedral ceiling, so people on the loft cant throw stuff down on people below. So far, I added exterior to attic floor level, but, as you can see in sections, it works only for the exterior perspective view, and I messed framing badly. And everything else. So far, I couldn't find solution to that. -I also disallowed myself to use "Build roof planes", and "Auto rebuild roofs" options, because I needed to place gable wall between two exterior wall set far apart, with void between, and only way I could think was to build exterior wall in the middle of the room (look at images), to create a roof planes, and then disable "Auto" option, delete that wall, and not to touch "Build roof planes" ever again. That was stupid, and I promise not to do that ever again. What I need here it to make a single gable roof placed on two small walls which are approximately 28' apart, and connected only by beams. I apologize for poor scan of my quick sketch, roll scanners make all kind of problems... -I am breaking my head with this for two days, and I must admit that I am really irritated. Not to mention the fact that I am really a Chief architect beginner, just in start of transition from AutoCad. So far, I came upon only one solution - to leave this exterior wall in the middle of the living room, and talk to client about turning their living room into squash club. But maybe I better try to make this work as intended. I would really appreciate any help.

Thank you CJS, I will hit the Suggestion forum, but I am not sure that this client will be willing to wait for x7 ... In meantime, I hope that somebody will come to something. Problem is that use of materials is really inaccurate this way.

Looks like attachment failed...

I am trying to modify roof layers, by adding additional insulation layers (see detail in attached image). What I had in mind was to make roof type, like in BUILD - WALL- Define wall types, but it looks like there is no such option for roofs. So, what I need to do is to add 3 layers of polyiso, in total thickness od 5", one layer of 1/2" plywood and another layer of roof membrane ABOVE rafters. I lost like day and a half trying to find an answer to this, but no luck so far. Anybody any ideas?
